I hope you are all doing well. I am currently facing an issue while trying to set up the SNMP subagent functionality for my InterSystems Cache installation.
I am using InterSystems Cache for Windows (AMD64) version 5.2.4 (Build 809_0_9006U). The SNMP subagent functionality requires the iscsnmp.dll dynamic library, which I have been unable to locate in my installation directory.
Today I would like to address a subject that has given me a hard time. I am sure this must have been the case for quite a number of you already (so-called “the bottleneck”). Since this is a broad topic, this article will only focus on identifying incoming HTTP requests that could be causing slowness issues. I will also provide you with a small tool I have developed to help identify them.
Our software is becoming more and more complex, processing a large number of requests from different sources, be it front-end or third-party back-end applications. To ensure optimal performance, it is essential to have a logging system capable of taking a few key measurements, such as the response time, the number of global references and the number of lines of code executed for each HTTP response. As part of my work, I get involved in the development of EMR software as well as incident analysis. Since user load comes mostly from HTTP requests (REST API or CSP application), the need to have this type of measurement when generalized slowness issues occur has become obvious.
Our team is working on building dashboard for internal reference and monitoring.
We would like to have details like Interface Name, Current Status, Last Messages Processed at, IP & Port, Serve/Instance/Production Environment name etc.
If there is any built-in service which we can utilize or any pre-compiled code that we can utilize to build such dashboard.
At this moment want to keep it basic, but moving forward will enhance with more advance features.
In the Windows Ressource Manager I can observe multiple parallel processes coming from cache.exe with read operations to journaling files.
All except one of these processes have the same reads(Byte/s). The processes point to different journal files and constantly read between 200 and 3000 Bytes/s.
The corresponding process via PID in the management portal of Caché shows the process %SYS.Monitor.Control.1. In 3 days of uptime on the server it has run 181.632.583 commands and modified 32.140.642 globals.
My employer set up a web-based HL7 interface monitor dashboard that will display all Ensemble components (Service/Process/Operation) in a Production, their status, and the support information embedded in each interfaces listing on the Monitor. Please see 3 screenshots.
This is part of the URL that we go to when accessing this Web based Monitor: ......57772/csp/healthshare/monitor/Rush.Monitor.Web.Home.cls
I'm using the EnumerateJobStatus query of class Ens.Util.Statistics to obtain the LastActivity value of a Business Host.
I would expect that this would return the timestamp of the last message received by the BH, understanding that any connect/disconnect activity would reset that timer. However, the time returned appears to actually be the time at which Ens.MonitorService generated the alert and is not directly related to anything that happened in the BH itself.
With more and more hospital applications built, business interface data processing may be affected by a variety of factors (network, consumer systems, etc.), there is an excessive accumulation of messages or even cause interface lag, affecting the routine performance of hospital IT systems , so the monitoring of the business interface components queue is increasingly important.
While current Intersystems IRIS platform's built-in queue monitoring only displays real-time queue information for interface components, which is limited in providing the queue data information needed by hospitals. The queue monitoring component program is based on the Intersystems IRIS platform and can monitor all interface components and display component queue information within 24h of the component, as well as query component historical queue data by setting a time period to better meet the needs of current in-hospital applications.
With the gradual improvement of hospital information construction, there are more and more business interfaces in hospitals. Due to the influence of various factors (network, consumer system, etc.), the data processing of business interface may cause excessive message accumulation and even the situation of interface card congestion, which affects the normal business development in the hospital. Therefore, the monitoring of the queue of business interface components becomes more and more important.
1. A deployment may consist of two high availability instances and two disaster recovery instances in a different data center.
The corresponding UAT environment could replicate this giving a total of 8 instances. How do you confirm CPF and Scheduled task alignment across ALL instances.
I've been trying for a while to come up with a set of tools to monitor the health of a mirror set and email a report nightly on the status of the mirror, or flag issues in real time. Making sure that all the databases are caught up, that all the mirror members are online.
Alerts are messages generated by production components. InterSystems IRIS automatically writes the alerts to a log file and sends then to the production component named Ens.Alert. If your production does not have a component named Ens.Alert, then InterSystems IRIS writes alerts to the log file but does not send them to any component. The component named Ens.Alert can be of any class. The most frequently used classes for Ens.Alert are:
I have a problem on enabling SNMP monitoring on Cache.
I installed on HP UX NET SNMP 5.7.2 package from HP Software Center and enabled agentX protocol in snmpd.cfg.
When I enabled full debugging on Cache and NET SNMP I discovered that sent and received packets on both sides are not the same. Some bytes are different. I think the problem is in default charset for TCP/IP connection which is on our system set to CP1250 instead of default RAW. So result is that Cache notifies are not visibile from snmpwalk etc.
InterSystems Production Monitor is a page in Management Portal to display monitoring information for the current running production. I like the page as it comes, but one size does not fit all.
On May 13, 2022 I read this post on Developer Community:
Currently we are using an older Healthshare instance but I am not opposed to using IRIS as we will upgrade eventually.
Currently for monitoring productions we have a Montior screen. We have both the Queues page and a Deepsee dashboard which has current status of our services. The issue with the Deepsee method we currently have with traffic lights is 1) the page is a bit slow to load the metrics 2) any new services from the team a new widget needs created and although this is easy enough to do it just is time consuming.
From time to time, we get the previous question in support, something or someone is using more licenses than expected, and we need to find what.
We have two scenarios. The first scenario is when we realize that the licenses are exhausted when the application does not work or when we try to connect through the terminal and get the "lovely"
Im trying configure the Caché Monitor Manager (^MONMGR) utility for send alert e-mails. Following the steps I have doubs to configure the options in "Set Server" to send e-mails for hotmail or outlook (smtp-mail.outlook.com). I dont know how can I configure Mail server SSLConfiguration for hotmail or outlook. Could you give me help? Thank you!
