Werk #15863: Add default aggregation modes for some clustered services during update

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.
