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 PRTG core server 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
- Subfolders in the PRTG Program Directory
- PRTG Data Directory

- Handling Sensitive Files
- Structure of the Logs Folder
- Windows Registry
- HTTP Full Web Page Sensor: Cached Files
- Auto-Update Files
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 can find your data there.
Subfolders in the PRTG Program Directory
You can find the following folders in the PRTG program directory:
Folder |
Description |
---|---|
\cert |
Certificates used by PRTG |
\Custom Sensors |
Custom sensor templates, custom scripts, and example scripts |
\devicetemplates |
Default and custom device templates |
\download |
Downloads from PRTG |
\lookups |
Standard lookup files maintained by PRTG The \lookups subfolder contains the \custom subfolder to store your customized lookups. |
\MIB |
Management Information Base (MIB) files referenced by sensors |
\notifications |
Custom notifications and notification sounds |
\PRTG Installer Archive |
PRTG Network Monitor installers for the currently installed version and the previously installed version |
\python |
Python environment files |
\Sensor System |
Sensor configuration files |
\snmplibs |
SNMP library files and converted .oidlib files |
\webroot |
PRTG web interface data |
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 can 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.
Files and Subfolders in the PRTG Data Directory
You can find the following files in the PRTG data directory:
File |
Description |
---|---|
PRTG Configuration.dat |
Monitoring configuration (for example probes, groups, devices, sensors, users, maps, reports, and more) This configuration file is the central storage for all your credentials, such as passwords and secrets used by PRTG for authentication. Handle all configuration files as sensitive, even if there are already security measures in place in your system. For recommendations on how to handle your configuration files in a secure manner, see Handling Sensitive Files below. |
PRTG Configuration.old |
Backup of previous version of monitoring configuration |
PRTG Graph Data Cache.dat |
Precalculated data for the graphs throughout the PRTG web interface (if missing, this file is automatically recalculated from the files in the monitoring database) |
You can find the following folders in the PRTG data directory:
Folder |
Description |
---|---|
\Configuration Auto-Backups |
Backup versions of the PRTG Configuration.dat file |
\Log Database |
Database with the recent event history for the whole system: menu option Logs in the PRTG web interface |
\Logs |
Text file based logs For more information, see section Structure of the Logs Folder. |
\Monitoring Database |
Results of all monitoring requests for all sensors (required for historic reports) |
\Report PDFs |
Older PDF reports stored in the file system |
\System Information Database |
Retrieved system information for the categories hardware, users (loggedonusers), processes, services, software, system (in according subfolders) |
\Ticket Database |
Database with all tickets (ticketdata.dat) |
\ToDo Database |
Database with all ToDo entries The ToDo feature is deprecated as of PRTG 14.1.8 |
Files that contain data such as passwords, secrets used for authentication, keys used to encrypt or decrypt other files are considered sensitive files. In PRTG, the configuration files are the central storage for all your credentials. As such, treat configuration files and all other sensitive files with the highest level of security, even if there are already security measures in place in your system.
PRTG contains some of its own security measures. For example, when you create a support bundle within PRTG that contains the configuration file, all secrets are removed or masked before the file is included in the support bundle. Administrators should not depend solely on PRTG and their operating system (OS) to secure the configuration files, but rather ensure that the security and access control for these files are maintained during transit, deployment, and storage (e.g. backups).
See some recommendations for good security practices when handing sensitive files in the table below:

System settings on 32-bit systems:

HTTP Full Web Page Sensor: Cached Files
If you use the HTTP Full Web Page, files might be cached in this directory:
C:\Windows\System32\config\systemprofile\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5
PRTG automatically saves downloaded software versions in the \download subfolder of the PRTG program directory. The compressed prtg.zip file that contains all necessary files is also cached there.
