This article applies to PRTG Network Monitor versions 7 and 8
How PRTG Network Monitor Stores its Data
PRTG Network Monitor stores its data
- into files in subfolders of the data folder (monitoring configuration, monitoring data, logs)
- into the registry (license key, admin login, IP settings, etc.)
Data Stored in the File System
The default setting of the data folder depends on the PRTG Network Monitor version you are using (7 or 8). The paths are also different if you have upgraded from version 7 versus installed a new version 8.
On all Windows versions, the default data folder is located at either
%ALLUSERSPROFILE%\Application data\Paessler\PRTG Network Monitor\V7
or
%ALLUSERSPROFILE%\Application data\Paessler\PRTG Network Monitor\V8
Tip: To directly open an Explorer Window showing the respective folder, click on "Run..." in the Windows Start Menu (shortcut Windows+R), paste the path above into the "Open:" field and click "OK".
However, the default setting can be changed. To find the right path for your PRTG installation, please go the PRTG Server Administrator and look up the path in the Core Server tab. You can also change the path there.
