This prometheus exporter is used to serve metrics for pacemaker https://github.com/ClusterLabs/pacemaker

It should run inside a node of the cluster or both.

You can find RPM pkgs for the exporter here: https://build.opensuse.org/package/show/server:monitoring/prometheus-ha_cluster_exporter

Once installed run inside a cluster node the exporter with:

systemctl start prometheus-ha_cluster_exporter, by default it will expose on http://YOUR_HOST_IP:9002/metrics.

If you open a web-browser it will serve the metrics.

The exporter can't work outside a HA cluster node

Hint: For a terraform deployment you can read also : https://github.com/SUSE/ha-sap-terraform-deployments

• expose cluster node and resource metrics via crm_mon (pacemaker data xml)

• expose corosync metrics (ring errors, quorum metrics)

• expose SBD disk health metrics

Build the binary with make and run it inside a node of the ha cluster , it will expose the metrics on port 9002 by default.

Use ha_cluster_exporter -h for options.

For the technical design of the exporter have look at design (this is focused on cluster_metrics)
