Sample Prometheus alerting rules

[cameronkerrnz]

Hello, I am interested in using your exporter to help monitor my two-node cluster that has DRBD version 9 with a master-slave relationship, a floating IP and filesystem and a MariaDB systemd service managed by pacemaker. I was particularly happy to see that you have DRBD version 9 support.

I've had one failure mode that I've encountered thus far caused by a matching kernel module that was missing after a kernel update that lead to a split-brain scenario. My experience with Pacemaker thus far has only been a couple of two-node clusters on CentOS.

Do you have any prometheus alerting rules you could share as a starting point?

Thanks,
Cameron

@cameronkerrnz hi thx for you issue.
Yes, we place the alerts here: https://github.com/SUSE/ha-sap-terraform-deployments/blob/master/salt/monitoring/prometheus/rules.yml

Also we have the dashboards grafana here:

As note, this are alerts as "showcase" so some adaption might needed.

Let me know.
