Change Report Timeout Value

By default, PRTG allows the generation of a report to take nearly up to one hour before there is a timeout. When generating very large reports, however, you may need to increase this time by adding a new value to the Windows registry.

Important: Always back up your system before manipulating the Windows registry!

Take the following steps to change the timeout value for report generation in the Windows registry:

1. On the system that runs the PRTG core server, open the registry editor.

2. 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\

3. Add a new String with the name ReportTimeout.

4. Set this to a value in seconds to change the timeout. For example, set it to 7200 for a timeout of 2 hours.

5. To activate the new setting, restart the PRTG core server service. For more information, see the PRTG Manual: PRTG Administration Tool on Core Server System


  • To reset the timeout to default, delete the respective string from the registry.
  • When running a cluster, take these steps on every node to make sure that the changed timeout value is also set when a node in Failover Master mode generates reports.
