How can I change the number of remote probes updated simultaneously?



When updating my PRTG core server, all connected remote probes are updated subsequently. I have a lot of remote probes and would like to limit the number of updates performed at once (to reduce peaks in bandwidth usage). How can I achieve this?

This article applies to PRTG Network Monitor 9.2 or later

Simultaneous Update of Remote Probes

Since version 9.2, after a core server update, PRTG updates all connected remote probes at once, deploying the new executables. Depending on the number of remote probes and available bandwidth, this might cause bandwidth issues. In order to limit the number of remote probes updated at a time, you can set a registry value.

Set Registry Value

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

  1. Open the registry editor
  2. Navigate to the right key
    • For a 64-Bit Windows system, go to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Paessler\PRTG Network Monitor\Server\Core\
    • For a 32-Bit Windows system, go to HKEY_LOCAL_MACHINE\SOFTWARE\Paessler\PRTG Network Monitor\Server\Core\
  3. Change the DWORD value ProbeUpdateMaxNew to your liking. We recommend using 10 (Decimal) if you experienced issues before.

This is not working for me, when ever i reboot the server or restart the "PRTG Core Server" service the value reverts back to 10000.

Please try stopping the services first and change the value in the registry, while the services are not running. After restarting the services, the value should bring the exspected effect.

This proved to be very useful for our setup. It would be even more useful to be able to configure this setting in the web interface.

Could Paessler consider adding this to the wishlist?

@mbrennan: The setting is in the registry by intention as this should only be changed if really necessary and if there are issues with the default value. So moving this feature to the web interface is not planned. Sorry.
