Microsoft has released a management pack for Lync Server 2013. The new management pack is compatible with SCOM 2007 R2 and SCOM 2012. The MP can coexist with the MP for Lync Server 2010. There is guidance how to configure that coexistence. This new management pack introduces some additional features compared to the previous version for Lync Server 2010. Now you can assign computers to be watcher nodes. What is watcher node:
Watcher nodes are computers that periodically run Lync Server synthetic transactions. Synthetic transactions are Windows PowerShell cmdlets that verify that key user scenarios, such as the ability to sign in or to exchange instant messages, are working as expected.
The new mp, the installation files for watcher nodes and the guide you can find here.
Remember to read the guide first.
