Some days ago Microsoft released the initial version of the BizTalk Server 2013 Monitoring MP, version 7.0.1033.0.
Compared to the BizzTalk Server 2010 Monitoring MP is slightly better. Much of the noise has been taken care off. However, for what I’ve heard from the community, the Display Names in both MPs are the same. So when you have BizzTalk Server 2010 and 2013 in place and want to monitor both, you’ll end up with DOUBLE names in the SCOM Console .
MP can be downloaded from here.
