Re: [Check_mk (english)] Monitoring clusters where from two distributed nodes
Actually, the cluster in question is a Windows 2012 R2 pair with a dynamic witness. So it basically only
fails over (manually) to one direction anyway. As such, we are also consider monitoring the service in a
1) Both servers are monitored
2) On secondary (standby) server, the services are monitored, but (cmk) service state is set to OK
regardless of whether the service is running
This means that an alert is generated if the system fails over (services on node #1 go down or node #1 goes
missing) and troubleshooting can begin. If needed, the rule to set service status to OK regardless of real
state can be removed (if need to run with node #2 for extended periods).
Have to check if BI is better than this...

as far as I know, clustered services only work if both cluster members are on the same check_mk server. You
could work with BI Aggregations however, and the check the state of this BI aggregation within a check that
you assign to your cluster host.
