Work Description: erwindon opened a new pull request, #4668:
URL: https://github.com/apache/activemq-artemis/pull/4668
See https://issues.apache.org/jira/browse/ARTEMIS-4497
my design decision:
re-use the code from the implementation of {{listNetworkTopology}} and add
it separate to provide these metrics:
* artemis_cluster_lives_count
* artemis_cluster_backups_count
this is a bit of code duplication, but prevents risk of breaking a
refactored {{listNetworkTopology}}

> Key: ARTEMIS-4497
> URL: https://issues.apache.org/jira/browse/ARTEMIS-4497
> Project: ActiveMQ Artemis
> Issue Type: Improvement
> Components: Clustering
> Affects Versions: 2.31.2
> Reporter: Erwin Dondorp
> Priority: Minor
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The broker has functions to export metrics to a metrics-interface-provider
> (e.g. [https://github.com/rh-messaging/artemis-prometheus-metrics-plugin] for
> collection using REST).
> This is only a subset of what can be collected using the JMX interface. (and
> the JMX interface has real commands too).
> Information on the cluster-topology was not yet available in these metrics.
> Due to the numeric nature of the metrics, providing the full topology of the
> cluster (as JMX operation {{listNetworkTopology}} does) is not possible. But
> just providing the broker-count is already very valuable.
> the following 2 metrics can be exported:
> * artemis_cluster_lives_count
> * artemis_cluster_backups_count
> With this information available, administrators can be alerted about various
> issues in the cluster. Detailed analysis can be done using the JMX info
> and/or the Console.
> a PR has been added to add that information to the set of metrics.
