This post is dedicated to the task of monitoring a Caché instance using SNMP. Some users of Caché are probably doing it already in some way or another. Monitoring via SNMP has been supported by the standard Caché package for a long time now, but not all the necessary parameters are available “out of the box”. For example, it would be nice to monitor the number of CSP sessions, get detailed information about the use of the license, particular KPI’s of the system being used and such. After reading this article, you will know how to add your parameters to Caché monitoring using SNMP.

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

13:08:59 :Attempting initial TCP connection(s) with 1 Cache instances ...
13:08:59 :Get connection with ENSEMBLE on port 1972
13:08:59 :Connection refused on port 1972, check if Cache instance ENSEMBLE is started.
13:08:59 :Cache iscsnmp.dll initialized for 1 configs

Ensemble and all productions are running. I've set up Caché SNMP agent on many other servers in our company and those are working fine. However this one server won't budge.

The following steps show you how to display a sample list of metrics available from the /api/monitor service.

In the last post, I gave an overview of the service that exposes IRIS metrics in Prometheus format. The post shows how to set up and run IRIS preview release 2019.4 in a container and then list the metrics.

This post assumes you have Docker installed. If not, go and do that now for your platform :)

The current version of SAM creates Prometheus metric endpoints which appear to be handled correctly by the current prometheus scraper, however the metrics do not confirm to the current prometheus standard. The standard states:

Prometheus is one of the monitoring systems adapted for collecting time series data.

Hello,

I want to create a dashboard with a line graph that shows system availability over time. I used this code to create a Dashboard:

            Set tItem = ##class(%DeepSee.UserLibrary.Link).%New()
                Set tItem.fullName = "Availability"
                Set tPage = "Availability.UI.CSVImport.zen"
                Set tItem.href = $system.CSP.GetPortalApp($namespace,tPage)_tPage
                Set tItem.title = "Availability"
                Set tSC = tItem.%Save()

One of the topics that comes up often when managing Ensemble productions is disk space:

The database (the CACHE.DAT file) grows in a rate that was unexpected; or the Journal files build up at a fast pace; or the database grows continuously though the system has a scheduled purge of the Ensemble runtime data.

It would have been better if these kind of phenomena would have been observed and accounted for yet at the development and testing stage rather than on a live system.

For this purpose I created a basic framework that could aid in this task.

What does Ens.Debug("LogETN") show and where are you see it in Management Portal? Does is show only errors, successful messages, etc?

Hey Developers,

We're pleased to invite you to join the next InterSystems IRIS 2020.1 Tech Talk: DevOps on June 2nd at 10:00 AM EDT!

In this InterSystems IRIS 2020.1 Tech Talk, we focus on DevOps. We'll talk about InterSystems System Alerting and Monitoring, which offers unified cluster monitoring in a single pane for all your InterSystems IRIS instances. It is built on Prometheus and Grafana, two of the most respected open source offerings available.

Next, we'll dive into the InterSystems Kubernetes Operator, a special controller for Kubernetes that streamlines InterSystems IRIS deployments and management. It's the easiest way to deploy an InterSystems IRIS cluster on-prem or in the Cloud, and we'll show how you can configure mirroring, ECP, sharding and compute nodes, and automate it all.

Finally, we'll discuss how to speed test InterSystems IRIS using the open source Ingestion Speed Test. This tool is available on InterSystems Open Exchange for your own testing and benchmarking.

As per the documentation of QueueCountAlert:
Number of messages on this item's queue needed to trigger an Alert message to be sent. Note that no further alerts will be sent unless the number of messages on the queue drops below 80% of this number and then rises again to this number.
Note that this alert will be sent even if AlertOnError is False.
Zero means no alerts of this type will be sent.

Now, the question is,
If QueueCountAlert is set to 10, and the queue size become 11 we will be getting email once.

The MONITOR process (also called the Caché Monitor) scans the messages in your cconsole.log file and sends you emails based on the severity of those messages. The MONITOR is configured using the ^MONMGR utility in terminal.

The MONITOR should not be confused with the similarly named System Monitor, which checks a variety of system health and performance metrics and can log messages regarding them to the cconsole.log, where they can then be scanned by the MONITOR.

Hi

I want to get the total amount of time that a process is active or the timestamp that it was created/started.

I tried the %SYS.ProcessQuery class, but I did not find any related information.

Is there any way to get this information from a process?

I'm using Caché 2017.

Can someone direct me to where in the documentation we can find how consumption may be calculated for global storage?

EDIT: After receiving some responses, it seems I was unclear in my initial inquiry. I am looking to determine our rate of consumption of storage; however, I am having some difficulty in doing that.

In this article, we will discuss about Orphaned Messages.
