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

ID: 15863 Title: Add default aggregation modes for some clustered services during update Component: Checks & agents Level: 1 Class: Bug fix Version: 2.1.0p31 This Werk affects all users that monitor Checkmk clusters using the services listed below. It mitigates some of the incompatibilites listed in <a href="https://checkmk.com/werk/12908">Werk #12908</a> (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. <b>Note:</b> We can not do this for all affected plugins. The rules match on the service description, not on the plugin names. Consider for instance <tt>mrpe</tt>: we can't know what your service description looks like. The following cluster aggregation modes are configured during update (service description pattern / aggregation mode): LI: "Apache .* Status": <i>failover</i> LI: "Site .* statistics": <i>failover</i> LI: "BIG-IP vCMP Guests": <i>worst</i> LI: "Node service .*": <i>best</i> LI: "OMD .* performance": <i>failover</i> LI: "MSSQL .* File Sizes": <i>worst</i> LI: "MSSQL .* Locks": <i>worst</i> LI: "MSSQL .* Locks per Batch": <i>worst</i> LI: "MSSQL .* Page Activity": <i>worst</i> LI: "MSSQL .* Transactions": <i>worst</i> LI: "MSSQL .* Sizes": <i>failover</i> LI: "MSSQL Datafile .*": <i>failover</i> LI: "MSSQL Transactionlog .*": <i>failover</i> LI: "SSL Certificate .*": <i>worst</i> LI: "SAP HANA Disk .*": <i>best</i> LI: "SAP HANA ESS .*": <i>best</i> LI: "SAP HANA Events .*": <i>best</i> LI: "SAP HANA Instance Status .*": <i>best</i> LI: "SAP HANA Memory .*": <i>best</i> LI: "SAP HANA Process .*": <i>best</i> LI: "SAP HANA Replication Status .*": <i>best</i> Please review the rules to see if they suit your needs.
