I want integration with Microsoft Team Foundation Server (TFS) too.

Microsoft System Center Operations Manager 2012

Our internal testing could not get the v2.0 plug in to work with this version of SCOM.

Use

and pay particular attention to

We have completed integration and are testing with 2012. Be aware that while the computers are inserted into cmdb_ci_computer, the OS on that machine is updated into the computer record and does NOT get inserted into cmdb_ci_spkg, only programs found on the assets ADD REMOVE PROGRAM FILES table in SCCM will get imported.

This is what we will be struggling with as a result.

Has anyone seen integration with BBCA?

Lync integration would be a great addition that we could use.
