I was helping troubleshoot SCOM performance issues with a customer yesterday and came across something which could be contributing to the performance problems they’re experiencing.

They’re monitoring a large SQL estate, including a lot of SQL clusters (around 800). It seems that the SQL MP (2014 , but possibly also others) is creating a (sub)-group for each of those clustered pairs (ie. around 800 Groups, just for the SQL clusters) .

Is anyone familiar with this and, if so, have they seen it cause any performance problems in their or other environments? Thanks 🙂
