<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: PRTG Administration Tool on Remote Probe Systems

If you start the PRTG Administration Tools on a system on which a PRTG Remote Probe runs, you can define various probe related settings, restart services, and view log information. You can change many of these settings also via the system administration and the probe settings tab in the PRTG web interface.

Note: To get familiar with the different components of PRTG, we recommend that you read the Architecture section.

Note: All settings made here are only valid for the local installation running on the computer you open the program on. In order to change settings for another installation, for example, another remote probe installation, please log in to this computer and open the program there.

Note: This section describes the available settings in the PRTG Administration Tool when you open the tool on a PRTG remote probe system. If you open this program on the PRTG core server, you have also access to settings regarding your whole PRTG installation.

If you prefer a video introduction to the PRTG Administration Tool, see the More section below for more information.

From the PRTG Network Monitor group in Windows start menu, please select PRTG Administration Tool to open the application. You can choose from these options in different tabs:

When you close the program with the Ok button after changing settings, you are asked to restart the probe service in order to save the settings. Please confirm by clicking the OK button. Otherwise the changes are ignored.

Probe Settings for Core Connection

Define general settings regarding the probe and probe connections.

Probe Settings

Name of Probe

Enter a meaningful name to identify the probe. PRTG shows this name, for example, in the device tree, and in all alarms by default. Please enter a string.

Reconnect Time

Define the time that PRTG will wait until the probe tries to reconnect to the core server if the connection fails. Please enter an integer value.

Connection to PRTG Core Server

These settings will affect how the probe will connect to the core server. A probe is either a local probe or a remote probe. PRTG will automatically detect the type of probe and show the correct setting options.

Server (IPv4 address or DNS name)

If this probe is configured as the Local Probe of the PRTG core installation, it will connect to the core via which you cannot change.

If this probe is configured as a Remote Probe, enter the IP address or DNS name of the core server.

Probe GID

The Probe GID is a unique identifier for the probe. We recommend that you do not change it.

Exception: Only if you substitute an existing remote probe from a different computer, you have to copy the GID from the old probe to the new probe. To do so, click on the Edit GID... button and confirm the warning with Yes. You can then change the value. It is not possible to change the GID for a local probe.

Note: You can deny GIDs under System Administration—Core & Probes in the PRTG web interface.

Probe Access Key

You do not need an access key for Local Probe connections.

On a Remote Probe, the Probe Access Key must match one of the access keys configured in your PRTG core server installation. If it does not match, the remote probe will not be able to connect to the core server. Please see System Administration—Core & Probes section for more information.

Note: Also check allowed and denied IPs there to ensure that the core server accepts the IP address of the remote probe.

Confirm Access Key

If you enter an access key for a remote probe, enter it in this field again to assure correctness.

Path for Probe Data Storage


Define the data folder to which PRTG will store configuration and monitoring data. Click on the ... button to choose another folder on your system.

Note: Before changing the path, make sure you stop both services and copy all data to the new location.

Probe Settings for Monitoring

Administrative Probe Settings / Probe Settings for Monitoring

Define the IP address used for outgoing monitoring requests.

  • If there is more than one IP on the current system available, you can specify the IP address that will be used for outgoing monitoring requests of certain sensor types.
  • The setting is valid for all monitoring requests sent from this PRTG probe.
  • This setting will be used for sensors using the following connection types: HTTP, DNS, FTP, IMAP, POP3, Port, Remote Desktop, SMTP, and SNMP. Note: This feature does not support all sensor types for technical reasons.
  • This is useful for devices that expect a certain IP address when queried.
  • Default setting is auto. PRTG will select an IP address automatically.

Note: If you change this setting, some sensors might stop working. For example, sensors might show a Down status if the selected IP address is blocked on the way to or directly on the monitored device.

Outgoing IPv4

Define the IP address for outgoing requests using the IPv4 protocol. The list shows all IP addresses available on the current system. Choose a specific IP address or select auto.

Outgoing IPv6

Define the IP address for outgoing requests using the IPv6 protocol. The list shows all IP addresses available on the current system. Choose a specific IP address or select auto. For details about the basic concept of IPv6 in PRTG, please see IPv6 section.

Service Start/Stop

You can stop and start PRTG Windows service manually. Click the Stop Core Server resp. Stop Probe Service button to stop a service, and Start Core Server resp. Start Probe Service to start it again. Both actions usually take from a few seconds up to several minutes to complete. You can also restart the core server and probes via the PRTG web interface under Administrative Tools.

We recommend that you set a schedule for automatic restarts.

Scheduled Restart settings

Restart Options

For best performance, we recommend that you regularly restart the Windows servers on which PRTG is running. To do this automatically for PRTG, you can schedule an automatic restart. Choose between the following options:

  • No scheduled reboot or service restart: Do not perform any scheduled restart of services automatically. We recommend a manual restart every few weeks. You can initiate a restart of your PRTG core server and probes under System Administration—Administrative Tools in the PRTG web interface.
  • Scheduled restart of PRTG services: Restart all PRTG services on the system where this probe runs on. If you choose this option on the local probe, the PRTG core server will restart as well. Define a schedule below.
  • Scheduled system reboot (recommended): This is the recommended setting, although not set by default. Enter a schedule below. We recommend restarting Windows servers once a month for best performance.

Restart Schedule

This setting is only visible if you selected a schedule option above. Choose how often you want to restart PRTG services or the Windows server:

  • Once per week: Select a weekday and time below.
  • Once per month (recommended): Select a day of month and time below.

Specify Day

This setting is only visible if you selected a schedule option above. Select a specific day of a week (Monday to Sunday) resp. month (1st to 30th resp. Last). If you select Last, the restart will always be executed on the last day of the month, regardless of how many days the month has.

Note: If you select a date that does not exist in every month (for example, the 30th day in February), PRTG will automatically initiate the restart on the last day of this month.

Specify Hour

This setting is only visible if you selected a schedule option above. Select the time of day when PRTG will perform the restart.

Note: A Windows warning message will be displayed 10 minutes before restart to inform a logged in user. The actual restart time can differ up to 30 minutes from the settings you enter below!

Note: You can also define a restart schedule on the Settings tab of a probe, section Administrative Probe Settings, in the PRTG web interface.
