OCS Health Tests

UC Diagnostics contains the following health tests that each monitor one part of your OCS 2007 or OCS 2007 R2 servers:

To monitor a mixed Lync/Skype and OCS environment, you must establish two connections to the same environment - one as a Lync/Skype connection and the other as a OCS connection.

OCS Server Health Test

OCS Server Health Test

The OCS Server health test allows you to monitor the basic health of all your OCS servers. It is recommended that you configure two server health tests - one test without monitoring event logs set with an interval of 30 minutes and a second test for monitoring event logs that runs only once a day. For more information on test settings, see the Unified Communications Diagnostics User Guide.

This test allows you to monitor the following types of information:

•
Network availability
•
Operating system disk space usage
•
Any Performance Counter
•
Any Windows service
•
Any Event Log entry

The required configurations and permissions also apply to OCS 2007 R2 servers.

Test prerequisites

See the following tables for the test targets, required configuration, and the required permissions for this test.

You can run the test against the following target servers.

3
Add OCS Diagnostic Users to the RTCUniversalReadOnlyAdmins group.
4
Add OCS Diagnostic Users to the Power Users and Performance Monitor Users security group on each OCS server through a GPO or some other mechanism.
