We've had some issues recently in which we've discovered that no events have been collected for a period of several days, but the manager is up and running as far as we can tell. The issue appears to have been resolved by upgrading to v6.3, however it's raised the following questions regarding how the agents on our Windows servers process collected events.
Thanks for the help.
I'm not aware of any specific internal events to capture the scenario mentioned in point #2, but I would certainly recommend keeping an eye on Internal Alert/Error/Exception/Warning if/when this happens again. If it happens again I would also recommend raising a technical support ticket & they could capture & analyse manager/agent debug logs which may provide some clues also.
