Prometheus is an open-source monitoring and alerting solution, whose particular strength is the collection of time series data, with the ability to easily query that data. There is much more information about these metrics in the MQ KnowledgeCenter and other blog posts. Publish/subscribe gives easy isolation for monitors. An early prototype of the MQ exporter for Prometheus used the RESET QSTATS command just to prove the concept, but that is not a good command to use in general when you have any other tools that may also use it. One huge benefit of the pub/sub model is that this data can be collected without interfering with any other monitoring programs. MQ V9 (and the MQ appliance) makes many statistics available through a pub/sub interface. This blog shows how it all fits together. One of the reasons for creating that Go package was to enable the creation of a program that sends MQ statistics to Prometheus and hence to be easily visualised in Grafana. In a previous blog entry I wrote about using the Go language with MQ.
