I was recently working with a customer where I was engaged to assist with troubleshooting several errors that were occurring in the Operations Manager event log across a SCOM Management Group. Because there were multiple errors occurring across several agents, the customer was having a difficult time tracking down which errors were occurring and which server they were occurring on. It proved very difficult to parse alerts and log into individual servers and event logs to try and identify issues, much less correlate the issues across the environment. After taking some time to understand the challenge, it seemed to me like a great opportunity to use OMS!
OMS Log Search gives us the ability to 1) identify all error events occurring in the Operations Manager event log (or almost any other log) across all servers in the environment and 2) allows us to then show all computers where each error is occurring without ever logging into a server. Very cool!
