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=3D"https://checkm=
k.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 forme=
r 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 descript=
ion 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.
