Looking at the output of checklogs, I can see when, where, and more importantly IF LEM receives events from non-agent devices. This GREATLY helps in troubleshooting. However, I am not sure I can answer these questions for servers sending events to LEM via an agent.
1. Is it possible on LEM to see when an event was received from an agent?
2. Where are the events from a Windows Agent stored on LEM?
3. Where are the events from a Solaris Agent stored on LEM?
