Prometheus exporter for HA clusters (pacemaker). SAP/HANA clusters

ha_cluster_exporter

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.

Usage:

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

Once installed run the exporter inside a cluster node with:

systemctl start prometheus-ha_cluster_exporter. By default it will show 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 also read: https://github.com/SUSE/ha-sap-terraform-deployments

Features:

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

• show corosync metrics (ring errors, quorum metrics)

• show SBD disk health metrics

Devel:

Build the binary with make and run it inside a node of the ha cluster, it will show the metrics on port 9002 by default. Use ha_cluster_exporter -h for options.

Design:

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