I use an filecontentsensor on an Windows 2008 networtshare to montior an mailserver. I got not everytime actial values. Whe I show to the file the content is different to the sensor. Update the sensor dos not change this. If I go to the mailserver an kill the SMB Session by "net session /Delete" all ist fine until any hours.. At 0:00 the mailserver renames the file and recreate the file.

is there an problem or an workaround?

Hello,

this appears to be some odditiy in the SMB-Share/Session. Would there be an option to access the target file without going over the SMB-Share? Maybe if its a local folder on a Windows based PC, with a Remote Probe running on it?

best regards.

No, the target is not local. Why this happens? Ist the symptom related to the Host or to the client?

That's very hard to say. Would a scheduled task (in Windows) be possible, that copies the file to the PRTG Host every minute or every 5 minutes, so that the File-Content sensor can check it locally?

But since one hour, the new sensor dos not update the values, but the filecontent has been changed.

Now i have the logfiles local on the probe and copy them by the mailserver every 5 minutes to the probe. Update the sensor dos nothing. Only when I change sensorsettings, then the value will be updated one time. (switch from regex to text or to regex)

None of the filecontentsensors has changed since they scan local files on the probe. I have crosschecked, the filecontent has changed.

I have checked.... The timestamp of the logfiles is everytime 00:00 because the will be recreated at 00:00. If I don´t copy the files and transfer them via c:>type file.log >server/share/file1.log all works fine because the hase an changedate every time. Is there an caching issue?

The sensor does not cache files. This has to be a cache then on Windows level.

Solved - for me - I have modified my linuxscript an add this two lines

printf("\n")
echo PAESSHEND

Since this modificatoins the sensor runs without any problems.
