Scott!Want to invite you to participate in the Second Developer Community Contest!Hope we will not show errors in leaderboard this time :)

# InterSystems Data Platforms and performance - Part 5 Monitoring with SNMP In previous posts I have shown how it is possible to collect historical performance metrics using pButtons. I go to pButtons first because I know it is installed with every Data Platforms instance (Ensemble, Caché, …). However there are other ways to collect, process and display Caché performance metrics in real time either for simple monitoring or more importantly for much more sophisticated operational analytics and capacity planning. One of the most common methods of data collection is to use SNMP (Simple Network Management Protocol). SNMP a standard way for Caché to provide management and monitoring information to a wide variety of management tools. The Caché online documentation includes details of the interface between Caché and SNMP. While SNMP should 'just work' with Caché there are some configuration tricks and traps. It took me quite a few false starts and help from other folks here at InterSystems to get Caché to talk to the Operating System SNMP master agent, so I have written this post so you can avoid the same pain. In this post I will walk through the set up and configuration of SNMP for Caché on Red Hat Linux, you should be able to use the same steps for other \*nix flavours. I am writing the post using Red Hat because Linux can be a little more tricky to set up - on Windows Caché automatically installs a DLL to connect with the standard Windows SNMP service so should be easier to configure. Once SNMP is set up on the server side you can start monitoring using any number of tools. I will show monitoring using the popular PRTG tool but there are many others - [Here is a partial list.](https://en.wikipedia.org/wiki/Comparison_of_network_monitoring_systems) Note the Caché and Ensemble MIB files are included in the `Caché_installation_directory/SNMP` folder, the file are: `ISC-CACHE.mib` and `ISC-ENSEMBLE.mib`. #### Previous posts in this series: - [Part 1 - Getting started on the Journey, collecting metrics.](https://community.intersystems.com/post/intersystems-data-platforms-and-performance-%E2%80%93-part-1) - [Part 2 - Looking at the metrics we collected.](https://community.intersystems.com/post/intersystems-data-platforms-and-performance-%E2%80%93-part-2) - [Part 3 - Focus on CPU.](https://community.intersystems.com/post/intersystems-data-platforms-and-performance-%E2%80%93-part-3-focus-cpu) - [Part 4 - Looking at memory.](https://community.intersystems.com/post/intersystems-data-platforms-and-performance-part-4-looking-memory) # Start here... Start by reviewing Monitoring Caché Using SNMP in the [Caché online documentation](http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=GCM_snmp). ## 1. Caché configuration Follow the steps in _Managing SNMP in Caché_ section in the [Caché online documentation](http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=GCM_snmp) to enable the Caché monitoring service and configure the Caché SNMP subagent to start automatically at Caché startup. Check that the Caché process is running, for example look on the process list or at the OS: ps -ef | grep SNMP root 1171 1097 0 02:26 pts/1 00:00:00 grep SNMP root 27833 1 0 00:34 pts/0 00:00:05 cache -s/db/trak/hs2015/mgr -cj -p33 JOB^SNMP Thats all, Caché configuration is done! ## 2. Operating system configuration There is a little more to do here. First check that the snmpd daemon is installed and running. If not then install and start snmpd. Check snmpd status with: service snmpd status Start or Stop snmpd with: service snmpd start|stop If snmp is not installed then you will have to install as per OS instructions, for example: yum -y install net-snmp net-snmp-utils ## 3. Configure snmpd As detailed in the Caché documentation, on Linux systems the most important task is to verify that the SNMP master agent on the system is compatible with the Agent Extensibility (AgentX) protocol (Caché runs as a subagent) and the master is active and listening for connections on the standard AgentX TCP port 705. This is where I ran into problems. I made some basic errors in the `snmp.conf` file that meant the Caché SNMP subagent was not communicating with the OS master agent. The following sample `/etc/snmp/snmp.conf` file has been configured to start agentX and provide access to the Caché and ensemble SNMP MIBs. _Note you will have to confirm whether the following configuration complies with your organisations security policies._ At a minimum the following lines must be edited to reflect your system set up. For example change: syslocation "System_Location" to syslocation "Primary Server Room" Also edit the at least the following two lines: syscontact "Your Name" trapsink Caché_database_server_name_or_ip_address public Edit or replace the existing `/etc/snmp/snmp.conf` file to match the following: ############################################################################### # # snmpd.conf: # An example configuration file for configuring the NET-SNMP agent with Cache. # # This has been used successfully on Red Hat Enterprise Linux and running # the snmpd daemon in the foreground with the following command: # # /usr/sbin/snmpd -f -L -x TCP:localhost:705 -c./snmpd.conf # # You may want/need to change some of the information, especially the # IP address of the trap receiver of you expect to get traps.

Examples are shown below about how to increase the # level of access. # # By far, the most common question I get about the agent is "why won't # it work?", when really it should be "how do I configure the agent to # allow me to access it?" # # By default, the agent responds to the "public" community for read # only access, if run out of the box without any configuration file in # place. The following examples show you other ways of configuring # the agent so that you can change the community names, and give # yourself write access to the mib tree as well. # # For more information, read the FAQ as well as the snmpd.conf(5) # manual page. # #### # First, map the community name "public" into a "security name" # sec.name source community com2sec notConfigUser default public #### # Second, map the security name into a group name: # groupName securityModel securityName group notConfigGroup v1 notConfigUser group notConfigGroup v2c notConfigUser #### # Third, create a view for us to let the group have rights to: # Make at least snmpwalk -v 1 localhost -c public system fast again. # name incl/excl subtree mask(optional) # access to 'internet' subtree view systemview included .1.3.6.1 # access to Cache MIBs Caché and Ensemble view systemview included .1.3.6.1.4.1.16563.1 view systemview included .1.3.6.1.4.1.16563.2 #### # Finally, grant the group read-only access to the systemview view. # group context sec.model sec.level prefix read write notif access notConfigGroup "" any noauth exact systemview none none After editing the `/etc/snmp/snmp.conf` file restart the snmpd deamon. service snmpd restart Check the snmpd status, note that AgentX has been started see the status line: __Turning on AgentX master support.__ h-4.2# service snmpd restart Redirecting to /bin/systemctl restart snmpd.service sh-4.2# service snmpd status Redirecting to /bin/systemctl status snmpd.service ● snmpd.service - Simple Network Management Protocol (SNMP) Daemon.

Testing MIB access MIB access can be checked from the command line with the following commands. `snmpget` returns a single value: snmpget -mAll -v 2c -c public vsan-tc-db2 .1.3.6.1.4.1.16563.1.1.1.1.5.5.72.50.48.49.53 SNMPv2-SMI::enterprises.16563.1.1.1.1.5.5.72.50.48.49.53 = STRING: "Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2015.2.1 (Build 705U) Mon Aug 31 2015 16:53:38 EDT" And `snmpwalk` will 'walk' the MIB tree or branch: snmpwalk -m ALL -v 2c -c public vsan-tc-db2 .1.3.6.1.4.1.16563.1.1.1.1 SNMPv2-SMI::enterprises.16563.1.1.1.1.2.5.72.50.48.49.53 = STRING: "H2015" SNMPv2-SMI::enterprises.16563.1.1.1.1.3.5.72.50.48.49.53 = STRING: "/db/trak/hs2015/cache.cpf" SNMPv2-SMI::enterprises.16563.1.1.1.1.4.5.72.50.48.49.53 = STRING: "/db/trak/hs2015/mgr/" etc etc There are also several windows and \*nix clients available for viewing system data. I use the free iReasoning MIB Browser. You will have to load the ISC-CACHE.MIB file into the client so it knows the structure of the MIB. The following image shows the iReasoning MIB Browser on OSX.  ## Including in Monitoring tools This is where there can be wide differences in implementation. The choice of monitoring or analytics tool I will leave up to you. _Please leave comments to the post detailing the tools and value you get from them for monitoring and managing your systems. This will be a big help for other community members._ Below is a screen shot from the popular _PRTG_ Network Monitor showing Caché metrics. The steps to include Caché metrics in PRTG are similar to other tools.  ### Example workflow - adding Caché MIB to monitoring tool. #### Step 1. Make sure you can connect to the operating system MIBs. A tip is to do your trouble-shooting against the operating system not Caché. It is most likely that monitoring tools already know about and are preconfigured for common operating system MIBs so help form vendors or other users may be easier. Depending on the monitoring tool you choose you may have to add an SNMP 'module' or 'application', these are generally free or open source. I found the vendor instructions pretty straight forward for this step. Once you are monitoring the operating system metrics its time to add Caché. #### Step 2. Import the `ISC-CACHE.mib` and `ISC-ENSEMBLE.mib` into the tool so that it knows the MIB structure. The steps here will vary; for example PRTG has a 'MIB Importer' utility. The basic steps are to open the text file `ISC-CACHE.mib` in the tool and import it to the tools internal format. For example Splunk uses a Python format, etc. _Note:_ I found the PRTG tool timed out if I tried to add a sensor with all the Caché MIB branches. I assume it was walking the whole tree and timed out for some metrics like process lists, I did not spend time troubleshooting this, instead I worked around this problem by only importing the performance branch (cachePerfTab) from the `ISC-CACHE.mib`. Once imported/converted the MIB can be reused to collect data from other servers in your network. The above graphic shows PRTG using Sensor Factory sensor to combine multiple sensors into one chart. # Summary There are many monitoring, alerting and some very smart analytics tools available, some free, others with licences for support and many and varied functionality. You must monitor your system and understand what activity is normal, and what activity falls outside normal and must be investigated. SNMP is a simple way to expose Caché and Ensemble metrics. I was asked a couple of questions offline, so the following is to answer them: _Q1. In your article, why do you say it is necessary to change information strings in snmpd.conf? (ie. syslocation/syscontact)?_ A1. What I mean is that you should change syslocation and syscontact to reflect your site, but leaving them as the defaults in the sample will not stop SNMP working using this sample `snmpd.conf`file. _Q2. you also mention basic errors you made in configuring it, which were these? It might be helpful to mention the debugging facilities for snmp `(^SYS("MONITOR","SNMP","DEBUG") )` as well?_ A2. One problem was misconfiguring the security settings in `snmpd.conf`. Following the example above will get you there. I also spun my wheels with what turned out to be a spelling (or case) error on the line `agentXSocket tcp:localhost:705`. In the end I figured out the problem was to do with agentX not starting by looking at the logs written to the `install-dir/mgr/SNMP.log` file. Caché logs any problems encountered while establishing a connection or answering requests in the `SNMP.log`. You should also check `cconsole.log` and the logs for snmpd in the OS. On Windows, iscsnmp.dll logs any errors it encounters in %System%\System32\snmpdbg.log (on a 64–bit Windows system, this file is in the SysWOW64 subdirectory). As pointed out in Fabian's question more information can be logged to the SNMP.log if you set ^SYS("MONITOR","SNMP","DEBUG")=1 in the %SYS namespace and restart the ^SNMP Caché subagent process. This logs details about each message received and sent. Thanks for the questions MO BTW Although I have not tried implementing - due to high number of Healthcare applications using Caché I thought it may be of interest that Paessler PRTG has developed new sensors for monitoring medical equipment that communicate via HL7 and DICOM.https://www.paessler.com/blog/2016/04/13/all-about-prtg/ehealth-sensors-know-what-is-going-on-in-your-medical-it I've installed PRTG on a windows 10 system... enabled SNMP services... I've configured SNMP Service to Community "public" destination "127.0.0.1"... PRTG is able to see and graph the system statistics... OK.Then I imported ISC-Cache.mib with Paesler MIB Imported, OK, and "Save for PRTG Network Monitor"... everything seems fine, but, then, where is supposed to be? When I go to PRTG NM I cannot see anyhing related to Caché ... no clue about the library that I supposedly just imported... S of SNMP means Simple... so I'm pretty sure I'm missing something really basic here, but I don't know how to go on. Found... I just got to go to add sensors to a group, windows type and snmp library... there it is the oidlib I had just imported!! When using containers (IRIS) how do use the host to proxy the snmp calls? is there a way to have the container use the hosts ip (and port 705) to do its reporting? Hi Jay, for the docker run command look at the --net=host flag. Also SAM might be of interest to you. See the recent announcement and a user case I hope it's helpful do we hv a similar topic for Cache on windows？Thx！

Caché Localization Manager CLM is a tool for localization/internationalization/adding multi-language support to a project based on InterSystems Caché. Imagine that you have a ready project where all the content is in Russian, and you need to add an English localization to it. You wrap all your strings into resources, translate them into English and call the necessary resource for Russian or English when necessary. Nothing tricky, if you think about it. But what if there are lots of strings and there are mistakes in Russian (or English)? What if you need to localize in more than one language – say, ten? This is exactly the kind of project where you should use CLM. It will help you localize the entire content of your project into the necessary language and retain the possibility to correct entries. CLM allows you to do the following: Add a new localization. Delete a localization. Export a localization. Import a localization. View two tables at a time. Conveniently switch between spaces. Check spelling. Let’s “look under the hood” now Caché has a standard approach to implementing I11N using the $$$TEXT macros: $$$TEXT("Text", "Domain", "Language") where: Text — the text to be used for localization in the future. Domain — modules in your applications. Language — the language of "Text". If you use $$$TEXT in COS code, data is added to the ^CacheMsg global during class compilation. And this is the global that CLM works with. In ^CacheMsg, everything is identical to $$$TEXT, you just add "ID" as the text hash. ^CacheMsg("Domain", "Language", "ID") = "Text" If you are using CSP, then the use of $$$TEXT in CSP will look as follows: <csp:text id="14218931" domain="HOLEFOODS">Date Of Sale</csp:text> Installation First of all, you need to download the Installed class from GitHub and import it to any convenient space in Caché. I will use the USER space. Once done, open the terminal and switch to the USER space. To start the installation, enter the following command in the terminal: USER> do ##class(CLM.Installer).setup() Installation process: You can make sure the application is installed correctly by following this link: http://localhost:57772/csp/clm/index.csp (localhost:57772 — the path to your server). Settings CLM uses Yandex to perform the translation. You will now need to obtain a Yandex API key to let it work. It's free, but needs registration. Let’s now deal with spellchecking. CLM uses Caché Native Access for SpellCheck implementation. CNA was written for calling external functions from dynamic libraries, such as .dll or .so. SpellCheck works with the Hunspell library and needs two files for spellchecking. The first file is a dictionary containing words, the second one contains affixes and defines the meaning of special marks (flags) in the dictionary. How words are checked: All words are packed from CLM and sent to Hunspell via CNA, where CNA converts them into a language that Hunspell understands. Hunspell checks every word, finds the root form and all possible variations, and returns the result. But where do we get all these dictionaries and libraries? — CNA: use an available release or build it on your own. — Hunspell: same thing, use an available version or download sources for making your own build. — We will also need a standard C language library. In Windows, it is located here: C:\Windows\System32\msvcrt.dll. — Dictionaries can be downloaded here. At the moment, 51 languages are supported: Albanian Czech German Latin Romanian Vietnamese Arabian Chinese Greek Latvian Russian Armenian Danish Hebrew Lithuanian Spanish Azeri Dutch Hungarian Macedonian Serbian Belarusian English Icelandic Malay Slovak Bosnian Estonian Indonesian Maltese Slovenian Basque Esperanto Italian Norwegian Swedish Bulgarian Finnish Japanese Polish Thai Catalan French Kazan Portuguese Turkish Croatian Georgian Korean Brazil Ukrainian The entire configuration process boils down to entering the paths to everything you got before. Open CLM in a browser. There is a “Set Paths” button in the upper right corner. Click it and you’ll see the next window. Use it to enter the required paths. Here’s what I got: Demonstration of a registration form localization Link to demonstration. Password and login: demo. Your critique, comments and suggestion are very welcome. The source code and instructions are available on github under an MIT license. An interesting article, but I'm puzzled by your use of the term "I11n". I'm familiar with "I18n" as an abbreviation for Internationalization (because there are 18 letters between the "I" and the "n". Likewise, I understand "L10n" as standing for Localization. Some Googling suggests that "I11n" is short for Introspection. Or have I missed something? Hi, John!i11n here stands for "internationalization" i18n - internationalization, but i11n is something else True. Title is fixed

Maybe Learning Services could help you out but I can't grant you access to the kits on the WRC. Hello, I took this for a spin and noticed that the new Prometheus metrics are not available on it like they were in 2019.4 ? ( ie: https://community.intersystems.com/post/monitoring-intersystems-iris-using-built-rest-api ). Am I missing something or is the metrics api still under consideration to make it into this build ? The correct link is https://docs.intersystems.com/iris20201/csp/docbook/platforms/index.html. I fixed the typo in the post. Tanks for pointing that out! Seems to be there for me... Hello Jeffrey, We're currently working on IRIS for Health 20.1 build 197, and we were wondering what fixes or additions went to latest build 199. Intesystems used publish all fixes with each FT build version, is there such list? Thank you Yuriy The Preview has been updated with build 2020.1.0.199.0. This includes a variety of changes, primarily corrections for issues found under rare conditions in install, upgrade, and certain distributed configurations. None of these changes impacts any published API. Thank you for working with the preview and for your feedback! Hi Yuriy - Thanks for pointing this out. We did not prepare a list for this, but I did make a comment on this thread, including verifying that none of these changes impacts any published API. If there is a change resolving an issue you reported through the WRC, you'll see that this is resolved via the normal process. We will be publishing detailed changenotes with the GA release. -Jeff

Introduction InterSystems has recently completed a performance and scalability benchmark of IRIS for Health 2020.1, focusing on HL7 version 2 interoperability. This article describes the observed throughput for various workloads, and also provides general configuration and sizing guidelines for systems where IRIS for Health is used as an interoperability engine for HL7v2 messaging. The benchmark simulates workloads that have been designed to closely match live environments. The details of the simulation are described in the Workload Description and Methodology section. The tested workloads comprised HL7v2 Patient Administration (ADT) and Observation Result (ORU) payloads and included transformations and re-routing. The 2020.1 version of IRIS for Health has demonstrated a sustained throughput of over 2.3 billion (total inbound and outbound) messages per day with a commodity server using the 2nd Generation Intel® Xeon® Scalable Processors and Intel® Optane™ SSD DC P4800X Series SSD storage. These results have more than doubled the scalability from the prior Ensemble 2017.1 HL7v2 throughput benchmarking. Throughout these tests, IRIS for Health was configured to preserve first-in/first-out (FIFO) ordering, and to fully persist messages and queues for each inbound and outbound message. By persisting the queues and messages, IRIS for Health provides data protection in the event of a system crash, and full search and resend capabilities for historic messages. Further, configuration guidelines are discussed in the sections below, which will assist you in choosing an appropriate configuration and deployment to adequately meet your workload’s performance and scalability requirements. The results demonstrate that IRIS for Health is capable of satisfying extreme messaging throughput on commodity hardware, and in most cases allowing a single small server to provide HL7 interoperability for an entire organization. Overview of Results Three workloads were used to represent different aspects of HL7 interoperability activity: T1 workload: uses simple pass-through of HL7 messages, with one outbound message for each inbound message. The messages were passed directly from the Ensemble Business Service to the Ensemble Business Operation, without a routing engine. No routing rules were used and no transformations were executed. One HL7 message instance was created in the database per inbound message. T2 workload: uses a routing engine to modify an average of 4 segments of the inbound message and route it to a single outbound interface (1-to-1 with a transform). For each inbound message, one data transformation was executed and two HL7 message objects were created in the database. T4 workload: uses a routing engine to route separately modified messages to each of four outbound interfaces. On average, 4 segments of the inbound message were modified in each transformation (1 inbound to 4 outbound with 4 transforms). For each inbound message four data transformations were executed, four messages were sent outbound, and five HL7 message objects were created in the database. The three workloads were run on a physical 48-core system with two Intel® Scalable Gold 6252 processors with two 750GB Intel® Optane™ SSD DC P4800X SSD drives running Red Hat Enterprise Linux 8. The data is presented as the number of messages per second (and per hour) inbound, the number per second (and per hour) outbound, as well as the total messages (inbound plus outbound) in a 10-hour day. Additionally, CPU utilization is presented as a measure of available system resources at a given level of throughput. Scalability Results Table-1: Summary of throughput of the four workloads on this tested hardware configuration: * Combined workload with 25% of T1 / 25% of T2 / 50% T4 workload mix Workload Description and Methodology The tested workloads included HL7v2 Patient Administration (ADT) and Observation Result (ORU) messages, which had an average size of 1.2KB and an average of 14 segments. Roughly 4 segments were modified by the transformations (for T2 and T4 workloads). The tests represent 48 to 128 inbound and 48 to 128 outbound interfaces receiving and sending messages over TCP/IP. In the T1 workload, four separate namespaces each with 16 interfaces were used, and the T2 workload used three namespaces each with 16 interfaces, the T4 workload used four namespaces each with 32 interfaces, and the final “mixed workload” used three namespaces with 16 for T1 workload, 16 for T2 workload, and 32 for T4 workload. The scalability was measured by gradually increasing traffic on each interface to find the highest throughput with acceptable performance criteria. For the performance to be acceptable the messages must be processed at a sustained rate, with no queuing, no measurable delays in delivery of messages and the average CPU usage must remain below 80%. Previous testing has demonstrated that the type of HL7 message used is not significant to the performance or scalability of Ensemble; the significant factors are the number of inbound messages, the size of inbound and outbound messages, the number of new messages created in the routing engine, and the number of segments modified. Additionally, previous testing has shown that processing individual fields of an HL7 message in a data transformation is not usually significant to performance. The transformations in these tests used fairly straightforward assignments to create new messages. Note that complex processing (such as use of extensive SQL queries in a data transformation) may cause results to vary. Previous testing has also verified that rules processing is not usually significant. The routing rule sets used in these tests averaged 32 rules, with all rules being simple. Note that extremely large or complex rule sets may cause results to vary. Hardware Server Configuration The tests utilized a server with 2nd Generation Intel® Scalable Gold 6252 “Cascade Lake” processors providing 48 cores @ 2.1GHz on a 2-socket system, 24 cores per socket with 192 GB DDR4-2933 DRAM, and 10Gb Ethernet network interface. Red Hat Enterprise Linux Server 8 operating system was used for this test with InterSystems IRIS for Health 2020.1 Disk Configuration Messages passing through IRIS for Health are fully persisted to disk. In the case of this test two Intel 750GB Intel® Optane™ SSD DC P4800X SSD drives internal to the system were used splitting the databases on one drive and the journals on another. In addition to ensure real-world comparison synchronous commit is enabled on the journals to force data durability. For the T4 workload as described previously in this document, each inbound HL7 message generates roughly 50KB of data, which can be broken down as described in Table 2. Transaction journals are typically kept on line for less time than message data or logs and this should be taken into account when calculating the total disk space required. Table 2: Disk Requirement per inbound HL7 T4 Message Contributor Data Requirement Segment Data 4.5 KB HL7 Message Object 2 KB Message Header 1.0 KB Routing Rule Log 0.5 KB Transaction Journals 42 KB Total 50 KB Recall that the T4 workload used a routing engine to route separate modified messages to each of four outbound interfaces. On average, 4 segments of the inbound message were modified in each transformation (1 inbound to 4 outbound with 4 transforms). For each inbound message four data transformations were executed, four messages were sent outbound, and five HL7 message objects were created in the database. When configuring systems for production utilization, net requirements should be calculated by considering the daily inbound volumes as well as the purging schedule for HL7 messages and the retention policy for journal files. Additionally, appropriate journal file space should be configured on the system so as to prevent the journal disk volumes from filling up. The journal files should reside on physically separate disk from the database files, for both performance as well as reliability considerations. Conclusion InterSystems IRIS for Health HL7v2 message throughput demonstrated in these tests illustrates the massive throughput capabilities with a modest 2-socket commodity server configuration to support the most demanding message workloads of any organization. Additionally, InterSystems is committed to constantly improving on the performance and scalability from version to version along with taking advantage of the latest server and cloud technologies. The following graph provides an overview and comparison of the increase in throughput from the previous Ensemble 2015.1 and Ensemble 2017.1 benchmarks with the Intel® E5-2600 v3 (Haswell) processors and Ensemble 2017.1 benchmark with 1st Generation Intel® Scalable Platinum Series (Skylake) processors respectively to latest results with the 2nd Generation Intel® Scalable Gold Series (Cascade Lake) processors running IRIS for Health 2020.1. Graph-1: Message throughput (in millions) per 10-hour day on a single server InterSystems IRIS for Health continues to raise the bar on interoperability throughput from version to version along with offering flexibility in connectivity capabilities. As the above graph shows the message throughput has increased significantly and, in case of T2 workloads, doubled from 2017, and comparing to 2015 more than tripled throughput in the same 10-hour window and sustained over 2.3 billion total 24-hour message rates. Another key indicator of the advancements of IRIS for Health is the throughput improvement in the more complex T2 and T4 workloads which incorporates transformations and routing rules as opposed to pure pass-through operation of the T1 workload. InterSystems is available to discuss solutions for your organizations interoperability needs. Hi Mark! These are impressive results! Do you have the link to the previous Ensemble 2017.1 HL7v2 throughput benchmarking results? They used to be available on our website, but have since been removed since the results where from 3 years ago. The summary results from 2015 and 2017 have been included in graph-1 above in this new report for comparison. Thanks. hi Mark Bolinsky ; I am student , I need HL7 Benchmark to test the process that I implemented. Please, can you help me get it?

Please welcome - #IRIScontest This hashtag is already on InterSystems Developers' social networks: Twitter, Facebook, Telegram and LinkedIn. Let the world know about the Intersystems IRIS Contest! Please share! 😉 Hi Developers! Only 3 days left before the start of the Intersystems IRIS Programming Contest! You will have 2 weeks (April 13-26) to upload your solutions to the Open Exchange and compete for the main prizes. So join our competition and win! 😎 These competitions appear to demand the use of Cache ObjectScript rather than any other language. Is this correct? And if so, why can't other languages be used instead? Hi Rob! The official name of the language is InterSystems ObjectScript or just ObjectScript - it's not only for Caché any more ;) And if so, why can't other languages be used instead? Every contest has a topic. First one was about ObjectScript CLI. The current is about Intersystems IRIS REST API or web sockets interface. There is no ObjectScript requirement in this particular contest directly but it's obviously involved. Because if you even generate the REST API using spec-first approach you get endpoints but you need ObjectScript to write the logic. See examples in the article from @Eduard.Lebedyuk or another from @David.Reche. And next month we are having a Native API contest where applications using python, node.js, .NET, java are very welcome. I updated my reply. Yes, ObjectScript is needed in this contest to implement REST API business logic. Introduced the 3rd technology bonus: usage of a spec-first approach! You get the bonus if you generate the REST-API in Intersystems IRIS with swagger spec using Open API services. Learn more in the documentation. See examples: one, two, three. And this is also a very nice example of spec-first by @Guillaume.Rongier7183! Hi Community! We start tomorrow! Are you ready to participate in our exciting contest? 🚀 Provided a few details on the requirements, possible application types, and bonuses. How to apply for the Programming Contest Log in to Open Exchange, open your applications section. Open the application which you want to apply for the contest and click Apply for Contest. Make sure the status is 'Published'. The application will go for the review and if it fits the topic of the contest the application will be listed on the Contest Board. Hi Rob! We provided more details for the contest - and indeed you can avoid using ObjectScript in the contest!You can use already existing! E.g. are extremely in need of the Frontend for the Forms 2.0, something line Vue, or react would be great! Or you can use any out-of-the-box IRIS REST API. So, provided Intersystems IRIS is used as the back-end database for the data persistence of the APIs, the competition allows the use of any other technologies in front of it? eg QEWD/Node.js + browser UI? The competition allows using REST API on the Intersystems IRIS side. If QEWD/Node.js + browser UI does this, then go ahead. That depends on your definition of "REST API on the Intersystems IRIS side". That Intersystems IRIS provides the HTTP interface? and/or the code that does the work of the API is within IRIS and therefore ObjectScript? As far as QEWD is concerned, Intersystems IRIS is simply a persistent JSON store with no other role (though you still can invoke ObjectScript methods and access classes if you want), so a REST API is implemented in JavaScript and handled by Node.js/QEWD. Sure, you can interpret Intersystems IRIS in any way it works for your application, but in this contest, we want to focus on REST API on Intersystems IRIS side. That means you either use any internal 6 api (Atelier, UIMA, iKnow, DocDB, MGMNT, BI, Monitoring) or any installed from Open Exchange or build your own with Swagger and/or ObjectScript. In that case I'll wait for a different competition :-) The registration period has already begun! Follow our Contest Board and stay tuned. Waiting for your cool projects! Hi Developers!

Hi Developers! This post describes how you could publish your InterSystems application on Open Exchange. What is the InterSystems application? It could be anything, which is built with InterSystems data platforms or to help work with InterSystems data platforms: InterSystems IRIS, InterSystems IRIS for Health, InterSystems HealthShare, InterSystems Ensemble and InterSystems Caché. This could be tools, frameworks, adapters, examples and business solutions. Why publish on Open Exchange? InterSystems Open Exchange is an "App Central" for the solutions in InterSystems. It's the first place where the developer goes to look for tools, frameworks, and examples on InterSystems IRIS. And Open Exchange brings the added traffic to your solution which could be converted into leads. We are having a set of business development tools for published Open Exchange applications. This definitely makes your InterSystems application more noticed. Submitting an application Suppose you have a library with open source published on Github which you want to publish on Open Exchange. For the purpose of a demo, I'll fork this remarkable project of @Peter.Steiwer ObjectScript-Math which I forked and renamed to object script-super-math. First of all, you need to sign in. You can do this using your DC account or create a new one (which will be suitable for DC too). Once signed in you'll see Profile Menu available which has My Apps section: Click on a New button to submit a new InterSystems application: OEX has a nice integration with Github which allows filling all the matching fields from the Github repo. E.g. let's try with objectscript-super-math: It imports the name, short description, license, Full description, Download URL. To have the application ready for publishing you just need to peek InterSystems Data Platform it works with and the related tags. Also, if there is an article on DC where you discuss the application, add the link to this article. If you publish not Github app with open source, but e.g. the solution you need to accurately fill all the mandatory fields: Name, Download URL, Short Description, License, Tags, Product. And the optional fields which you think should be filled. You also can add the related Youtube videos and two very important checkboxes: We'll talk about this later. Once you are happy with the fields you are welcome to Save the application. Before publishing the app you can set up the app's icon: Upload screenshots: And after that once you are ready, send it for approval on publishing: Here you need to submit the version and the release notes of the version. Release notes section supports Markdown so you can paste here very informative description with rich formatting on what are the changes come with the new release of your application. This will send the application to Open Exchange management for approval and once it's approved the application will be published on Open Exchange, you'll get the notification on email and the release news will be published on Open Exchange News. Next time we'll discuss profile setup, company setup and some special cases. Stay tuned! A tip for anyone trying to upload a different image for an already-published app. You need to unpublish it first, to make the "Upload image" option appear on the menu. See this GH issue comment. A related tip is that when you send your unpublished-and-modified app for approval you can override the default next version number that appears in the dialog, setting it to the same as the current version. You'll still have to enter something in the Release Notes field, but when your changes are subsequently approved your published app won't show any change in the Version History tab. John! Thanks for the heads up! It's really not very convenient! We'll fix it.

Hi Developers! In previous articles, we spoke on how to publish your application. But how to make Open Exchange work its best for your application? What do you want for your application on Open Exchange? It is attention (traffic) and downloads. Let's talk about how Open Exchange can deliver this. How Do I know how many downloads I have? There is an Analytics tab that is visible for the Author of application. It shows how many times users clicked on the Download button. We have a roadmap for this tab and soon will add the monthly info on Downloads and some other information and you are very welcome to submit what else do you want to see here. E.g. we plan to make this Downloads counter publicly available and make a sorting upon Downloads. Prepare your Application's page Your application's page should contain enough description of what the application does. This makes users want to click on the Download button. How to set up the description? If your application is the facade for a GitHub repo Open Exchange can import Readme.Md from your Github repo. E.g. like here: check the Open Exchange page and the related Github repo page So, in this case, you just need to properly maintain README.md file in the Github repo which will be automatically updated on Open Exchange. In case it is a non-Github application you setup the description on your own the Long Description field. This field supports markdown so you have rich formatting tools to describe the purpose, features, installation steps and usage terms. A good example of a Markdown description on Open Exchange. Make Regular Releases If your app is evolving this is noticed by users. Add the feature and don't forget to make a release on Developers Community. It takes 5 min but it adds the release notes to News, it places your app on top on the main page, it gets your subscribers notified on the new features your bring to your application. Post the Related Developer Community article You can tell a lot how to use your application and how people can benefit from its features? It's a great reason to write an article about it on Developers Community and highlight the features of your application. Of course, you will add the hyperlinks to your application page inside the text but you also can feature the application using DC tools. E.g. you can add the "Related Open Exchange Application" link and this will add a special button on top of your article and in the news feed and an URL to the app at the bottom of the application. See the Example. You also want to link back the application on Open Exchange to the article on DC: This will make the Discuss button active on the Application page. An average DC article gets about 800 reads so you can deliver additional traffic to your application using this channel. Easy installation and setup If your application has 12 steps of "How to install it" this probably doesn't help to increase the number of downloads. Ideally, this should be a one-step installation. If your application is InterSystems ObjectScript I recommend pack and publish it with an ObjectScript Package manager. This really makes your installation into one command: USER:zpm>install your-application Example. Use Your Global Masters' "Miles" Another way how you can get more traffic to your application page is to use Global Masters points. You may know we have a Global Masters advocates hub where we give points to participants for there contribution to InterSystems Community. The ways of the contribution could be articles, answers, and questions on DC, applications on Open Exchange (yes, you get GM points for submitting applications). So, you probably have some GM points(sign in with your DC or Open Exchange credentials) and if you give to the Community and the Community could give you back and you can use GM points to get more attention to your Open Exchange application. How? Google Ads promotion You can spend some points and set up a Google Adwords campaign of $1,000 which InterSystems will cover and manage. Learn more. App of the week We have "News blocks" on every page of Developers Community and this News block can tell about your Open Exchange application. Learn more. Your Application Screencast On InterSystems Developers Youtube If you have a screencast on the features of your application you can get more views and traffic publishing it on Developers Community Youtube. And the simplest and the most working approach: add the features which everybody likes and thus you get the most attention and downloads) Choose any recipes above or take all of them and boost the downloads of your InterSystems Application on Open Exchange! If you have any ideas on how we could better help to make your Open Exchange applications more noticed and helpful submit suggestions and bug reports here. Submit your InterSystems apps and stay tuned!
