This Werk affects all users that monitor Checkmk clusters using the services listed below. It mitigates some of the incompatibilites listed in Werk #12908 (please read the werk for full context).
During upgrade from Checkmk 2.0 to 2.1 we add some rules to restore the former behavior of clustered services.
Note:
We can not do this for all affected plugins. The rules match on the service description, not on the plugin names. Consider for instance mrpe: we can't know what your service description looks like.
The following cluster aggregation modes are configured during update (service description pattern / aggregation mode):
- "Apache .* Status": failover
- "Site .* statistics": failover
- "BIG-IP vCMP Guests": worst
- "Node service .*": best
- "OMD .* performance": failover
- "MSSQL .* File Sizes": worst
- "MSSQL .* Locks": worst
- "MSSQL .* Locks per Batch": worst
- "MSSQL .* Page Activity": worst
- "MSSQL .* Transactions": worst
- "MSSQL .* Sizes": failover
- "MSSQL Datafile .*": failover
- "MSSQL Transactionlog .*": failover
- "SSL Certificate .*": worst
- "SAP HANA Disk .*": best
- "SAP HANA ESS .*": best
- "SAP HANA Events .*": best
- "SAP HANA Instance Status .*": best
- "SAP HANA Memory .*": best
- "SAP HANA Process .*": best
- "SAP HANA Replication Status .*": best
Please review the rules to see if they suit your needs.
