This article applies to PRTG Network Monitor versions 7 and 8

How PRTG Network Monitor Stores its Data

PRTG Network Monitor writes data to several locations:

  • Into the program directory (core installation)
  • Into the data folder (monitoring configuration, monitoring data, logs, etc.)
  • Into the registry (license key, admin login, IP settings, etc.)

Program Directory

By default, PRTG's setup program stores the core installation in one of the following directories:

%programfiles%\PRTG Network Monitor

or

%programfiles(x86)%\PRTG Network Monitor

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 during setup. To find the right path for your PRTG installation, please look it up in the Properties of your Start Menu's PRTG icons.

Data Folder

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".

Note: Depending on the language and version of your Windows installation you might need to translate the substring Application data into your Windows installation's language (for example Anwendungsdaten for some German Windows versions).

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.

Files and Sub Folders in the Data Folder

The following files and folders are stored in the file system:

Registry

All settings (except license keys) of PRTG Network Monitor are stored in the registry under one of the following nodes, either

HKEY_LOCAL_MACHINE\SOFTWARE\Paessler\PRTG Network Monitor\V7

or

HKEY_LOCAL_MACHINE\SOFTWARE\Paessler\PRTG Network Monitor\V8
