Make agent install needs some of manual works.
After import MP, then next step is installing agent that makes it possible for monitoring by SCOM. If you try to add computer to manager from the Console, you encounter the following error. (It cannot go to the next step)
The error message is "there is no agent to install." This message is natural, SCOM doesn't have any CentOS agent. You only see existing other agent files.
So, What am I going to have to do with no agent? but, there is a workaround.
Both architectures of CentOS and Redhat are very similar. They are the twins come from the same kernel. Let's copy it from redhat agent and rename it like the below. I renamed it as "scx-1.0.4-265.centos.5.x86_64.rpm"
And the next step is modifying MP file named Microsoft.Linux.CentOS.5.xml.
The point is to make the same version between file name and the xml.
The first version number in agent's name,1.0.4, should be matched "version" element in the MP. And the second number, 265, should be matched "Build" element.
After finish modifying the mp file, you have to import it again to SCOM. Compare to the first figure, it is able to go the next step.
Agent is installed successfully.
To verify, I queried the information of the linux server, then communication worked fine.
