<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: Data Storage

PRTG stores the monitoring configuration, monitoring data, logs, tickets, and reports, as well as support and debug data into different subfolders in the PRTG data directory on the probe system. Additionally, there is data in the PRTG program directory (for example, scripts for your custom sensors) and in the Windows registry.

You cannot access these directories in PRTG Hosted Monitor.

In this section:

PRTG Program Directory

32-bit systems:

%programfiles%\PRTG Network Monitor

64-bit systems:

%programfiles(x86)%\PRTG Network Monitor

These are the default paths. If you specified a different installation directory, you find your data there.

PRTG Data Directory

On Windows Vista (not officially supported), Windows 7, Windows Server 2008 R2, Windows 8, Windows 8.1, Windows Server 2012, Windows 10, Windows Server 2016, or Windows Server 2019:

%programdata%\Paessler\PRTG Network Monitor

These are the default paths, depending on your Windows version. If you specified a custom path for data storage, you need to look it up in the PRTG Administration Tool on the PRTG Core Server tab. You find the path there.

The Windows ProgramData folder is hidden by default. To display it, you need to enable hidden items in the View options of your Windows system.
