PRTG Manual: PRTG Administration Tool on Remote Probe Systems

If you start the PRTG Administration Tool on a remote probe system, you can define various probe-related settings, restart services, and view log information. You can also change many of these settings via the system administration and the probe settings in the PRTG web interface.

icon-i-round-redThis section describes the available settings in the PRTG Administration Tool when you open it on a remote probe system. This is not the complete set of available settings. If you need access to all settings regarding the entire PRTG installation, open the PRTG Administration Tool on the PRTG core server system.

icon-i-round-redSettings you make here are only valid for the remote probe system on which you open the PRTG Administration Tool. Make sure that you log in to the system that you want to make changes to and open the PRTG Administration Tool there.

Start the PRTG Administration Tool

From the Windows Start menu, select the PRTG Network Monitor folder and click PRTG Administration Tool to open the application.

The PRTG Administration Tool has the following tabs:

After you change settings, click the Save & Close button. A new window opens where PRTG asks you to agree to restarting the PRTG probe service. Click OK to proceed.

Restart Services

Restart Services

Probe Settings for Core Connection

Define general settings regarding the remote probe and connections.

Probe Settings for Core Connection

Probe Settings for Core Connection

Probe Settings

Name of Probe

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

Reconnect Time

Define the time that PRTG waits for the remote probe to reconnect to the PRTG core server if the connection fails. Enter an integer value.

Connection to PRTG Core Server

These settings affect the way the remote probe connects to the PRTG core server.

Server (IPv4 Address or DNS Name)

Enter the IP address or Domain Name System (DNS) name of the PRTG core server.

Probe GID

The Probe GID (global ID (GID)) is a unique identifier for the remote probe. We recommend that you do not change it.

Exceptions: If you substitute a remote probe from a different computer, you have to copy the GID from the old probe to the new probe. To do so, click the Edit GID button and confirm the warning with Yes. You can then change the GID. PRTG checks if the GID is valid. You can also generate a new GID if necessary. To do so, click the Generate new GID button and confirm the warning with Yes.

icon-i-round-blueYou can deny GIDs under System Administration—Core & Probes in the PRTG web interface. If you remove a remote probe from the device tree or if you deny a remote probe after installation, PRTG automatically enters its GID in the Deny GIDs list.

Probe Access Key

The Probe Access Key must match one of the access keys in the PRTG core server installation. If it does not match, the remote probe is not able to connect to the PRTG core server.

icon-square-cyanFor more information, see section System Administration—Core & Probes.

icon-i-round-blueCheck also the allowed and denied IPs in System Administration—Core & Probes to ensure that the PRTG 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 the PRTG Data Directory on the Probe System

Path

Select the directory where PRTG stores configuration and monitoring data. Click the ... button to choose a different folder on your system.

icon-i-round-redBefore you change the path, make sure you stop both the PRTG core server service and the PRTG probe service and copy all data to the new location.

Language for the PRTG Administration Tool for Remote Probes

<your language>

Choose the language for the PRTG Administration Tool on the remote probe. The default is English.

Probe Settings for Monitoring

Probe Settings for Monitoring

Probe Settings for Monitoring

Define the IP address used for outgoing monitoring requests.

  • If more than one IP is available on the system, you can specify the IP address that PRTG uses for outgoing monitoring requests of certain sensors.
  • This setting is used for sensors using the following connection types: HTTP, DNS, File Transfer Protocol (FTP), Internet Message Access Protocol (IMAP), Post Office Protocol version 3 (POP3), Port, Remote Desktop, Simple Mail Transfer Protocol (SMTP), and Simple Network Management Protocol (SNMP).
  • The setting is valid for all monitoring requests that this remote probe sends.
  • This setting is useful for devices that expect a certain IP address when queried.
  • The default setting is auto. PRTG automatically selects an IP address.

icon-i-round-redThis feature does not support all sensors for technical reasons.

icon-i-round-redIf you change this setting, some sensors might stop working. For example, sensors might show a Down status if the IP address is blocked on the way to or directly on the monitored device.

IPv4: Outgoing IP for Monitoring Requests

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

IPv6: Outgoing IP for Monitoring Requests

Define the IP address for outgoing requests using the IPv6 protocol. The list shows all available IP addresses on the system. Choose a specific IP address or select auto.

icon-square-cyanFor details about the basic concept of IPv6 in PRTG, see section IPv6.

Service Start/Stop

You can manually start and stop the PRTG probe service. Click Start Probe Service to start the service or Stop Probe Service to stop it. Both actions usually take from a few seconds up to several minutes. You can also restart the PRTG probe service via the PRTG web interface under Administrative Tools.

icon-i-round-blueWe recommend that you schedule automatic service restarts.

Scheduled Restart Settings

icon-prtg-on-demandThis setting is not available on the hosted probe of a PRTG hosted by Paessler instance.

Restart Options

For best performance, we recommend that you regularly restart the probe system. Define if you want to schedule an automatic restart:

  • No scheduled restart of the system or PRTG services: Do not automatically perform a scheduled restart of services. We recommend that you manually restart PRTG every few weeks. You can initiate a restart of the PRTG probe service under System Administration—Administrative Tools in the PRTG web interface.
  • Scheduled restart of PRTG services: Restart the PRTG probe service on the probe system. If you select this option on the local probe, the PRTG core server service restarts as well. Define a schedule under Restart Schedule.
  • Scheduled system restart (recommended): We recommend this setting although it is not the default setting. Define a schedule under Restart Schedule. We recommend that you restart probe systems once a month for best performance.

Restart Schedule

This field is only visible if you select a schedule option above. Choose how often you want to restart the PRTG probe service or the probe system:

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

Day

This field is only visible if you select a schedule option above. Select a day of the week (Monday to Sunday) or month (1st to 30th or Last). If you select Last, PRTG initiates the restart on the last day of the month, regardless of how many days the month has.

icon-i-round-blueIf you select a date that does not exist in every month (for example, the 30th day in February), PRTG automatically initiates the restart on the last day of this month.

Time

This field is only visible if you select a schedule option above. Select the time of day when PRTG performs the restart.

icon-i-round-blueYou get a Windows warning message 10 minutes before the restart to inform you if you are logged in to PRTG. The actual restart time can differ by up to 30 minutes from the settings you enter here.

icon-i-round-blueYou can also define a restart schedule on the Settings tab of a remote probe in the PRTG web interface.
