<%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 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.

i_podYou 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

i_round_blueThese 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

i_round_blueThe \lookups subfolder contains the \custom subfolder to store your customized lookups.

\MIB

Management Information Base (MIB) files referenced by sensors

\notifications

PRTG Data Directory

On supported Windows versions:

%programdata%\Paessler\PRTG Network Monitor

i_round_blueThese 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.

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

i_round_blueYou 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)

i_round_redThis 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.

i_square_cyanFor recommendations on how to handle your configuration files in a secure manner, see Handling Configuration 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

i_square_cyanFor more information, see section Structure of the Logs Folder.

\Monitoring Database

\Ticket Database

Database with all tickets (ticketdata.dat)

\ToDo Database

Database with all ToDo entries

i_round_blueThe ToDo feature is deprecated as of PRTG 14.1.8

Handling Configuration Files

Configuration files are the central storage for all your credentials, such as passwords and secrets used by PRTG for authentication. 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). Handle all configuration files as sensitive, even if there are already security measures in place in your system.

Scenario

Example

Recommendations

In transit

  • Sharing files to customer support
  • Migration to a new server
  • Always use an encrypted or an offline channel to share the configuration files.
  • Do not share the configuration files with untrustworthy third parties.
  • Use the support bundle feature and share the raw configuration file only when specifically requested by support.

In deployment

  • Storing data in non-default paths
  • Ensure that any custom data path restrict access to those files to only users with high privileges (e.g. administrators).
  • Use the default path whenever possible.

In storage

  • Backups (which includes the configuration files) in the same or alternative location
  • Any backup containing files with sensitive information, like the configuration file, should be protected in the same manner as the live system.
  • Storing backups may erase or change the current access rights and result in more users being able to access the stored data. Always maintain the same level of access control on the paths where configurations files are stored as used in deployment.
