Troubleshooting Microsoft Monitoring Agent issues

To add more context to this issue, the agent seems to be able to transmit other OMS solution based data to OMS at normal intervals, so it may be an issue with this custom log.

One weird thing is that the client is saying the file is updated every five minutes, however the Date Modified timestamp for the file in Windows does not update throughout the day (not sure how that happens, but asking the client to verify). What triggers the Microsoft Monitoring Agent to recognize a file has been updated and to transmit data to OMS (is it that the Date Modified timestamp has changed, or is some kind of checksum calculation performed to recognize new data has been added)? Or does MMA simply stream anything new it sees in the log every 5 minutes regardless of if the Date Modified timestamp has changed or not.

Thanks!
