SCOM Zombie PSA#21: SCOM Agent Health “Not Monitored”

 

A while back a zombie pushed a large number of agents out to be installed. Without waiting until the job completed on the first management group, the zombie pushed the agents out to the same systems from another management group.

The end result was some of the systems showed up in one of the management groups as “Healthy”  while the other system either failed to install the agent or it showed up as “Not Monitored”.

Here is what Worked for me:

• Stop and disable the Agent Service (System Center Management). This also worked for some of the agents that I couldn’t successfully deploy a second agent on.
• From the management group with the “Not Monitored” agent I deleted the agent from my Agent Managed or from the Pending Management.
• if you delete the agent before the agent service is stopped/disabled it may reshow back up in the Pending Management. Even if you approve the agent, it will show back up as Not Monitored in the Agent Management.
• Next I rediscovered & redeployed the agent to the system (I did not uninstall the agent).
• My agent successfully installed and now it is properly reporting to multiple management groups with healthy status.

This worked for SCOM 2007 R2 and I bet SCOM 2012 it would resolve the same issue.
