@Charles_Yuliansen - There are a couple of known issues/limitations in Windows that you should be aware of:
- Can’t read log files from network volumes
- Open file handlers cause issues with Windows file rotation
To find-out what's going on, it would be good to run Filebeat with debug logging:
filebeat -e -d "*"
Once the issue happens, you can attach the debug logs.
I am also wondering which Filebeat version you are currently using?
