There will, no doubt, be full discussions elsewhere of the new MQ Native HA Cross-region Replication feature. But one aspect of it seemed particularly relevant to other articles on this site: monitoring the CRR metrics.
The MQ 9.4.2 release also includes another tool, mqperfck, that introduces some additional metrics. And I’ll talk about how that potentially affects other monitoring tools.

Previous articles in this series have shown OpenTelemetry (OTel) Context propagation for Node.js, Go and C/C++ MQ applications. You should read the first article for an introduction and explanation of the scenarios and problems that need solutions.
This (final?) entry discusses JMS applications.

The first article in this series introduced OpenTelemetry (OTel) tracing with IBM MQ. It showed how the trace context can flow when the application is using the MQ Node.JS or Go interfaces. This article carries on the story for OTel context propagation, this time talking about C++ and C applications.

OpenTelemetry (OTel) tracing relies on context being propagated from one component in an application stack to another. While IBM MQ does have some ability to carry that context with messages, the OTel SDK design does not make that flow automatic. This post shows how we can extract the context for some applications, and then use OTel context propagation techniques to improve the observability of applications using MQ.
In particular in this post, I’ll talk about applications using MQ with the Node.js and Go interfaces.

As I promised in a recent article, I am coming back to the OpenTelemetry topic. This time, it’s going to be about another pillar of the observability requirements – integrating MQ’s metrics with OpenTelemetry.

One recent addition to the plethora of observability tools is OpenTelemetry. It attempts to provide a vendor-agnostic set of common APIs, components, interfaces and protocols that enable interoperability between a range of other tools. It deals with three major pillars of telemetry data, the things you often need to look at when monitoring systems: traces (by which it means application-level data flows), metrics, and logs.
There are already ways of tracking messages through an MQ network and beyond, reporting via OpenTelemetry. And I will soon be talking a lot more about MQ metrics and OpenTelemetry. But as an appetiser, this post shows the third piece of the story: logs.
