Looks like the BizTalk 2006 & BizTalk 2006 R2 Management Pack for Operations Manager 2007 has been released and is available in the Management Pack Catalog.
To quote the catalogue entry, the management pack:
…is a entirely new … providing comprehensive discovery and monitoring of BizTalk Server components and applications. In addition to general support for BizTalk Server 2006, BizTalk Server 2006 R2, this management pack provides coverage for new BizTalk Server 2006 R2 features, such as the native EDI runtime and RFID.
I think its great that we now have native EDI and RFID monitoring ‘out of the box’ – no more need to cludge something together to monitor these two aspects of the product. I’d personally like to see this MP backported to MOM 2005, but I doubt that will happen!
