PRTG Manual: PRTG Administration Tool
The PRTG Administration Tool is part of your PRTG installation and it is where you can edit the administrative settings of local probe and remote probe installations.
You can start the PRTG Administration Tool from the Windows Start menu on the PRTG core server system or the remote probe system. If you start the PRTG Administration Tool on the PRTG core server system, you can change settings that affect the entire installation and the local probe. If you run the PRTG Administration Tool on a remote probe system, you can only change settings that are related to the remote probe.
Any settings that you change require a restart of the affected PRTG core server service and PRTG probe service to apply any changes on the configuration. See the following sections for details.
You can review the history of all changes to the settings of the PRTG Administration Tool in the \Logs\serveradmin subfolder of the PRTG program directory. The name of the corresponding logfile is ServerAdmin.log.
