This article applies to PRTG Network Monitor 8.1.2 or later

Change Report Timeout

By default, PRTG allows generation of one report to take nearly up to one hour before a timeout is reached. For almost all scenarios, this is a good setting. Only when generating very large reports, you may need to increase this time by adding a new value to the Windows registry.

Caution: Please backup your system before manipulating the Windows registry!

Step 1

  • On the system running the PRTG core server, open the registry editor.
  • For a 64-Bit Windows system, go to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Paessler\PRTG Network Monitor\Server\Webserver\
  • For a 32-Bit Windows system, go to HKEY_LOCAL_MACHINE\SOFTWARE\Paessler\PRTG Network Monitor\Server\Webserver\

Note: If you still use the deprecated PRTG versions v8 or v7, you will see v8 or v7 in the paths above.

Step 2

  • Add a new String with the name ReportTimeout.
  • Set this to a value in seconds to change timeout. For example, set it to 7200 for a timeout of 2 hours.


  • The new setting is active after a restart of the core server Windows service (see PRTG Administration Tool).
  • To reset timeout to default, please delete the string from the registry.
  • When running a cluster, please perform these steps on every node to make sure the changed timeout is also set when a node in Failover Master mode generates reports.
