Application Errors Analytics

Hi Developers!

As you know the application errors live in ^ERRORS global. They appear there if you call:

d e.Log()

in a Catch section of Try-Catch.

With @Robert Cemper's approach, you can now use SQL to examine it.

Inspired by Robert's module I introduced a simple IRIS Analytics module which shows these errors in a dashboard:

Hi All

I'm looking for the a simple-quick-easy solution to monitor a SQL table thought Ensemble.

I have a process that update a DataBase ,a scheduled task that runs every night (Not Ensemble)

In the end it updates a table (replica_status) with a new recored with two fileds: Id, DateTime

I looked around the community but didn't find an answerd case.

I'm thinking on a Task that will run a sql outboud adapter BO that checks that table and send a alert if no new record was created yesterday

is this the right approach or is there's a better solution?

Off the back of the Interface Monitoring post I had created a class that queries the Ens.AlertRequest global and returns the entries between 6pm the night before and 6am in the morning.

I tested this build in our T&D environments and the build worked very well.

However in our production environment the query is being truncated, by what I believe to be a timeout and I get a partial query output.

In the System>SQL pages my 12 hour query times out.

Using Grafana directly from IRIS

There have been some very helpful articles in the community that show how to use Grafana with IRIS (or Cache/Ensemble) by using an intermediate database.

But I wanted to get at IRIS structures directly. In particular, i wanted to access the Cache History monitor data that is accessible by SQL as described here

https://community.intersystems.com/post/apm-using-cach%C3%A9-history-mon...

and didn't want anything between me and the data.

Hi:

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.

Spoilers: Daily Integrity Checks are not only a best practice, but they also provide a snapshot of global sizes and density.

Update: Many of the below utilities now offer a mode to estimate the size with <2% error on average with orders of magnitude improvements in performance and IO requirements. I continue to urge regular Integrity Checks, however there are situations where more urgent answers are needed.

Ensemble monitoring

First post! In order to somewhat redeem myself for an unnecessary call to support, I've decided to post some classes that I've written to monitor certain metrics inside our Ensemble Live instance (yeah, Kyle, you WERE laughing at me, but it's okay). What the classes do is to run queries and code to get database sizes, status of the mirror, counts of rows in tables such as EnsLib.HL7.Message and Ens.MessageHeader. The data is collected and written to tables and then an email is sent out daily upon completion. I've found this quite useful in keeping an eye on what's going on. It's help

stdout logging

In The Business Process and the Business Operation, I am using the following code to get the value of TimeCreated and TimeProcessed

BP:

%Ensemble("Process").%PrimaryRequestHeader.TimeCreated

%Ensemble("Process").%PrimaryRequestHeader.TimeProcessed

BO:

..%RequestHeader.TimeCreated

..%RequestHeader.TimeProcessed

But I am trying to use ..%RequestHeader.TimeCreated in Business Service it is not storing any value.

How to get the value of TimeCreated and TimeProcessed in Business Service?

Http request response time monitoring

Hi developers!

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.

Hello,

I am currently having the experience activating prometheus for iris db.

This environment that I speak uses IKO as a base.

I need to put 3 notes in the iris service area.

Are they:

annotations:
   prometheus.io/path: "/monitor/metrics"
   prometheus.io/port: "52772"
   prometheus.io/scrape: "true"

I'm not finding this possibility in the IKO documentation.

Has anyone had this experience and can help us with this challenge?

I want to understand how this message is build:

[SYSTEM MONITOR] CPUusage Alert: CPUusage = 99, 99, 99 (Max value is 85).

Caché keep a log of cpu usage (99,99,99) and how is the frequency of check of this?

how can i chance the max value? is that possible?

Best,

Hello

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.

Is there a solution for this issue?

Whenever the Windows SNMP Service restarts, the snmpdbg log says the following.

16:58:25 :Debug tracing enabled for SNMP agent
16:58:25 :SnmpExtensionInit called, pid=4432, tid=12276

Hi,

We want to monitor an Ensemble Production and send custom email alerts in function of some Rules. For example, if we normally receive 1 message per second, if suddenly we receive 5 or more messages per second, we want to send an email alert. And if tomorrow we don't want to check this again, we want to disable it through Ensemble Business Rules.

Hi,

During the implementation of iris-history-monitor using ZPM, I'm bumping on the following scenario:

My Installer.cls has a call for the Custom Sensors Class method. The Custom information looks like a charm as I described in this article:

IRIS History Monitor using custom built-in REST API /api/monitor/metrics

But, now I'm trying to replicate the same behavior using the module.xml to work with ZPM.

Enterprise Monitor

Has anybody managed to get Enterprise Monitor to work to monitor multiple namespaces on manay instances?

I am hitting an issue trying to get a local instance namespace working.

I have this error for my first local namespace sytem configured.

Hello everybody,

In the documentation I read the following:

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:

Internally we use splunk for monitoring applications and network.

Does Ensemble have a way of exposing internal metrics and/or a way of exposing custom built metrics?

I've used Deepsee dashboards in the past to monitor Apache Tomcat/Apache Camel/hawtio using JMX rest calls. This is the other way around and ideally I'd like to expose metrics on:
