Manually Delete/Purge Log Files

Hello,

You can adjust the settings for the historic data purging at:

"Setup > System Administration > Core & Probes > Historic Data Purging"

If you scroll down, you see the purging configuration. Any value is the number of days for which PRTG keeps the data before deleting it. Within the next 24 hours the historical data will get deleted.

Also see: How and Where does PRTG store its data

Timo,

PRTG is not purging the files.

"How can I manually force the purging or deletion of log files?"

Wolfgang,

It is not possible to manually force the purging or deletion of log files. You'll either need to delete them manually (You'll find the Log Database file here: "\ProgramData\Paessler\PRTG Network Monitor\Log Database") or adjust the mentioned configuration and wait till PRTG deletes the files automatically. After changing the "Historic Data Purging" settings to you desires, the logs will get deleted within the next 24 hours automatically.

Hi at all

We have the problem, that on one of our Probes the ProbeWMI.log is over 350 GB big. It is located under C:\ProgramData\Paessler\PRTG Network Monitor\Logs\probe .

Which Value do i have to change / reduce for purging the ProbeWMI.log ? Historic Sensor Data?

Thanks in advance and kind regards Sebastian

Hello Sebastian,

The Data Purging feature deletes the data only on the PRTG Core server, it does not delete data on the Remote Probes.

The ProbeWMI.log file can be deleted manually, you will only need to stop the PRTG Probe service before doing this. After you start the probe service again, it will create a new ProbeWMI.log file.

Hello Sasa

Is there a disadvantage in deleting the log file? Are historical data missing or something like that?

Thanks and kind regards Sebastian

Hello Sebastian,

There is no disadvantage, the log file only records some errors or issues that occur on the WMI sensors, the sensor data and settings are stored on the PRTG core server.
