MMA Agent, cross platform, and Azure
Things that make you go hmmm....
Ran across a scenario where we were trying to connect Azure Cross-platform (Linux) VM's and MMA/SCOM agents to SCOM management group.
Management group was 2012R2, discovery wizard from SCOM console, failed to install agent, certificate errors.
