I would like to change the default string that is shown in the lower left corner of every graph shown in the PRTG web interface and the Windows GUI. Instead of the PRTG version, I would like to print my own text there.

How can I do this?

graphs prtg registry text

This article applies to PRTG Network Monitor 8.1.2 or later

Change PRTG Version Text in Graphs

By default, PRTG shows its name and version number in a small text line underneath each graph. You can change this text by adding a new value to the Windows registry.


Graph in PRTG Web Interface Show image in full size


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: For PRTG 8 you might see the values in the additional sub-key V7 or V8.

Step 2

  • Add a new String with the name GraphExtraText.
  • As value, set the text you want to appear underneath the graphs. If you want to show nothing in the lower left corner of your graphs, please enter three spaces " ".

Notes

  • The new setting is active after a restart of the core server Windows service (see PRTG System Administrator in manual).
  • To reset the text to default (PRTG name and version number), please delete the string from the registry, or set its value to an empty string.
  • Since PRTG version 8.2.0.1875, this setting is also valid when using the Windows GUI.
  • The setting is only valid for the core server on which you've just changed the registry. When running a cluster with additional core server installations, please perform these steps on every node to make sure the changed text is visible to users regardless of the node they connect to.

I'm trying to eliminate this string at the bottom of MAPS. Is this possible? All my maps have a string such as the following at the bottom:

Network Monitor 9.2.1.2308, Network Monitoring Software (c) 2012 Paessler AG ...

That's very likely the mapshot.htm/pagefooter.htm there, not the registry key explained in this article.

Is it also possible to change the graph footer that shows in the Enterprise Console?

This should also apply to the EC as it uses the same graphs as the webinterface. Did you already add the regkey?

Hi Stephan,

Yes we have a group policy to set the reg. key for all or core servers and the graphs on the web GUI show our custom foot. Enterprise Console shows the default PRTG graph footer.

Can't confirm - did you try to remove the connection and add it again? The string is also visible in the EC, since it's actually using the same graph images as the webinterface :)

Yeah, we've had it in place for a long time now and new clusters are picking it up. I assumed it would be the same as the graphs are from the same source... So when it didn't show I just assumed it would pick it up from a reg key on the local machine?

Reghacks are not distributed to failover nodes. Can you check if the key is in place on all servers and restart the core server service, just to make sure it's read?

The GPO put the reg key on all PRTG servers including failovers. I can confirm it's in place on all of them. We've had that key in place for at least a year and servers have been restarted many times and some are new. We have only just started using the EC now all our clusters are on the same version.

Can you check the graphs within the webinterface of the failover nodes - are they displayed correctly?

I know it's been a while since I last replied to this one. All master and failover nodes have the graph footer but I've never been able to get it to show in the EC.

Could you post a screenshot of the EC graphs? It should be there, but it looks blurred due to scaling.


Kind regards,
