MQ Metrics with OpenTelemetry

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.

Handling MQ logs and events 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.

MQ JMS and Spring: Spring Boot 2 now at end of regular support

Spring Boot 2 has now reached its “end of non-commercial support“. The lifecycle for that project is set by Spring’s owners; a major release typically has 2 years of open support before moving into a longer-term paid-for regime.

Options for MQ identities

I’ve written in earlier posts about confusion between different ways of using LDAP with MQ for authentication. Despite those articles, I still see questions from people who don’t really know what they can or should do.

As an attempt at simplifying the possibilities for a Linux environment, I drew up this chart. It is based on where your identities are defined.

Node.js Add-ons: Object transformation performance

While working on the redesigned Node.js C++ add-on for MQ, I had a question about transforming objects. What was the best method for Node.js performance? Noone answered the question on the internal channels I tried. I also couldn’t find anything definitive on external documentation or blogs. So I wrote my own tests …

MQI Node.js library: an experimental reimplementation

The MQI library for Node.js applications first appeared in 2017. One of the first articles about it is here. Regular maintenance and updates to the library ensured it kept up with newer MQ and NodeJS features. But it seemed time to do a more extensive rewrite of the package, and that’s why I’m writing this article. I’ve put an experimental reimplementation on GitHub of the library for you to try out, before it goes into the mainstream release. Originally in the “napi” branch, it’s been promoted to the master branch.

Update: This new version is now on npm as the ibmmq 2.0.0 release and has been merged into the main GitHub branch.

Monitoring MQ availability

One of the focus areas for new development in MQ in recent years has been in the area of High Availability and Disaster Recovery. Technologies such as RDQM and Native HA, and automatically managed logfiles, give a range of possibilities for ensuring your messaging systems continue reliably. Alongside the core function, there are also metrics and status information to show more about what is going on. And so the latest updates to the open source monitor programs add collection of some of these recently-added values. This should simplify monitoring MQ availability.
