<%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.

Subfolders in the PRTG Program Directory

The following folder is stored in the PRTG data directory:

Folder	Description	File Format
\Support Bundle	Collected and compressed log file data when sending a support bundle to the Paessler support team For more information, see the Knowledge Base: What is the best way to contact the Paessler support team?	LOG / TXT / ZIP

PRTG Data Directory

On supported Windows versions:

%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.

You can find the supported Windows versions in section System Requirements.
