A size limit is not implemented, but if the file is too large, it could be that reading it takes too much time, if it's not done locally. Please either try having the file smaller. Or (if possible), install a Remote Probe on the target machine, and scan the file locally.

I tried recreating the sensor and get the same results. The sensor was functioning properly before the update. The share is working and the user can access the file.

Hello,

thank you very much for your KB-Post. Does the normal File Sensor see the target file? Is this file on a Network share? Or a Windows based machine?
Did you try restarting the target machine, and also the PRTG Host machine?

best regards.

The normal File Sensor does see the target file. It is a windows share. I have restarted PRTG but not the target machine.

Thanks

Can you please try a smaller size for a test?

23mb file worked. Is there a file size limit.

I reset the log file thus reducing its size and it appears to be working. Thanks

So when the log file grows the sensor goes into a No Data state. This didn't happen under PRTG 13, only since the PRTG 14 upgrade.

Also I can't put a remote probe on the machine but I am scanning the file on a gigabit LAN with <1ms latency.

It may have been a simple coincidence that the file grew too large, in the moment the update to PRTG 14 was done.
I'm sorry, in the moment there is no other way, than keeping the file small.

I guess that's possible but unlikely since it logs the same activities it always has. Maybe it will be fixed in a later release.

We plan to improve the File Content Sensor, but I cannot put an ETA on this.
