#Monitoring

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?

In the Business Operation, how do we get to know which source is currently sending primary request if there are multiple requests coming at the same time?

Hi Developers,

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.

Hello,

In response to the infrastructure needs of our company's service, I've created a small API that sends SNMP queries to InterSystems to visualize relevant data for retrieval when the infrastructure implements monitoring.

However, I'm experiencing a timeout issue when attempting to collect information using an SNMP walk. Here is the code for my API's SNMP service:

I tried to monitoring IRIS with Zabbbix Server. Snmpwalk from Zabbix to IRIS success and got data from IRIS. But in message.log appears many warning message if snmpwalk running. 

I need to develop a tool to help to get what data is being consumed by a certain process, in order to get all data used to build an automated test scenario.

For example, some user process will pull data from ^GLOBAL(1)="dataString", ^GLOBAL(2)="dataString2", ^GLOBAL1(1)="data1String", ^GLOBAL2(4)="data2String4". Amidst all other data on these Globals, I will ignore everything that was not used in the user process, and get the specific keys used on it.

It appears to be working correctly, mirroring data etc. but the status on the Primary Cache DB is showing the wrong status for the DR DB.

 re-configured Cache Mirroring BUt  still have the same issue afterwards.

The GUI display remains the same regardless.

What's the way to get healthcheck info for an IRIS (container) running without PWS?

Is there any built-in functionality to send out an email or a text message when a mirror member fails?

Hello InterSystems Community Members,

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.

I have checked my installation directory thoroughly, typically located at C:\InterSystems\Cache, and its subdirectories, but I couldn't find the iscsnmp.dll file.

When installing IRIS, all the system AUDIT events are not enabled.

What is the fastest way to activate all events?

Hello, 

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. 

Please suggest, any help will be appreciated. 

Thanks,

Yash 

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.

Enterprise Monitor is a component of Ensemble and can help organizations monitor multiple productions running on different namespaces within the same instance or namespaces running on multiple instances.

Documentation can be found at:

http://docs.intersystems.com/ens20161/csp/docbook/DocBook.UI.Page.cls?KEY=EMONITOR_all#EMONITOR_enterprise

In Ensemble 2016.1 there were changes made to make this utility work with HealthShare environments.

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:

https://community.intersystems.com/post/creating-custom-monitoring-page

I agree with Mark that Production Monitor is complex. I liked the idea to create a nice clean clear monitor page.

I began to work on a Cache Server Page utilizing class methods to provide the production data.

Released with no formal announcement in IRIS preview release 2019.4 is the /api/monitor service exposing IRIS metrics in Prometheus format. Big news for anyone wanting to use IRIS metrics as part of their monitoring and alerting solution. The API is a component of the new IRIS System Alerting and Monitoring (SAM) solution that will be released in an upcoming version of IRIS.

Overview

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. Overview

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.

Hi everyone,

I have been reading up a bit on projection. I found a reference made to %Projection.Monitor on this page.

However, I cannot find any further information on %Projeciton.Monitor. What is it? How does it work? How do you use it? What value does it add?

Thank you.

Some Usage cases

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. 

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:

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 :)

Step 1. Download and run the IRIS preview in docker

In this article, we will discuss about Orphaned Messages.

What is an Orphaned Message

Every message body is associated with a message Header which holds the metadata. The Header holds information like source configuration name, target configuration name, time created, time processed, associated message body reference, session information, message body class name, message status. When there are message body records that do not have their corresponding Header records those are called Orphan message bodies. We will discuss possible causes which could end up with orphan message bodies.

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-mo…

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

InterSystems is pleased to announce the release of System Alerting & Monitoring (SAM) version 2.0.

What is SAM?

SAM marries IRIS’s standards-based Monitoring API and Log Monitor with familiar industry standard tools like Grafana and Prometheus to create a basic monitoring and alerting solution for IRIS clusters.

For more on SAM, see the System Alerting and Monitoring Guide.

What’s new in SAM 2.0?

The industry standard tools that SAM relies on have all been upgraded. 

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?
