Exchange 2010 MP Overrides

All of you that have encountered the new Exchange 2010 Management Pack for System Center Operations Manager 2007 R2 will probably notice a big difference, lots of changes when comparing it to the old 2003 or even 2007 MP. The big change is in the way alerts are treated by the system. A new correlation engine have been introduced that is sitting on the RMS server in a type of service.

I will not get into the process of going into the correlation engine, but any information about that can be found here.

Problem:

As for the Management Pack, many people have a problem with creating overrides for the new 2010 MP.

Every time we try to make a change in the severity or priority it ends up with no effect on the system and alert keep on going with the wrong values.

Cause:

New alerts that come to the RMS goes with a forwarding connector to the correlation service. from there the alert returns after some inner changes and into the related class.

Solution:

As the alerts goes through the correlation service its been regenerated on the RMS server. and this is key for our case.

If we want to make any override to work, we need to target the override to this RMS server as its hosting the rule/monitor and not the exchange servers.

The way to do that is by going to the Override menu and selecting the “For all objects of another class…”

ExchangeCapture1

In the window of Items to select, choose the Root Management Server as the target.

ExchangeCapture2

Make the Override you want, and that’s it.

Now your overrides are distributed and active
