We have a program that writes changes/logs to a txt file every minutes. This file does not update it's "modified date" for sometimes up to a week even tho there are changes being made to the file every minute. (As the file remains open when in use by the software)
How can I monitor the file so PRTG can tell me when the changes to the file stop happening? I tried using a checksum sensor but this only alerts me when changes are happening (every minute) not when they stop happening.
