Clean up diskspace Monitoring Database



Is there any way to clean up the monitoring database (.prd files) of PRTG?

Currently it is eating away about 500MB a day. The files are located in: D:\Paessler\PRTG Network Monitor\V8\Monitoring Database.

you could change the directory where PRTG stores its data


or you can use the purging limits

Hey luisalves,

Yes, if you delete the monitor database folder, you will loose all your historical data.

In order to cleanup your disk from old data (which you do not need anymore) we recommend to adjust the data purging settings under Setup >> System Administration >> Core&Probes >> HISTORIC DATA PURGING
