PRTG Manual: PRTG Administration Tool on Remote Probe Systems

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. Enter a string.

Reconnect Time

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

These settings affect the way the probe (local probe, hosted probe, or remote probe) connects to the core server. PRTG automatically detects the type of probe and shows the correct settings.

Server (IPv4 address or DNS name)

If this probe is configured as the local probe of the PRTG core installation, it connects to the core via 127.0.0.1, which you cannot change.

If this probe is configured as a remote probe, enter the IP address or Domain Name System (DNS) name of the core server.

Probe GID

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

Exception: 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 the Edit GID... button and confirm the warning with Yes. You can then change the value. You cannot change the GID for a local probe.

You 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

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 in your PRTG core server installation. If it does not match, the remote probe is not able to connect to the core server.

For more information, see section System Administration—Core & Probes.

Check 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

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

Before 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.

<your language>

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

Define the IP address used for outgoing monitoring requests.

• If more than one IP is available on the current 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 are sent from this probe.
• This setting is useful for devices that expect a certain IP address when queried.
• The default setting is auto. PRTG selects an IP address automatically.

This feature does not support all sensors for technical reasons.

If 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.

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, see section IPv6.

This 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 Windows servers on which PRTG runs. Define if you want to schedule an automatic restart:

• No scheduled reboot or service restart: Do not perform a scheduled restart of services automatically. We recommend that you manually restart PRTG 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. If you select this option on the local probe, the PRTG core server restarts as well. Define a schedule under Restart Schedule.
• Scheduled system reboot (recommended): We recommend this setting although it is not the default setting. Define a schedule under Restart Schedule. We recommend that you restart Windows servers 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 PRTG services or the Windows server:

• 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.

If 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.

You get a Windows warning message 10 minutes before the restart to inform you if you are a currently logged in user. The actual restart time can differ by up to 30 minutes from the settings you enter here.

Open Log Folder...

Open the PRTG Network Monitor data directory on your hard disk drive to access all logfiles that PRTG creates.

Send Logs to Paessler...

Open an assistant to send logfiles to the Paessler Support Team. See Send Logs to Paessler for details.

You can also send logfiles with the support bundle via the Contact Support option in the PRTG web interface.

Open Support Ticket...

Open the support form on the Paessler website in a browser window.

If you need help, we recommend that you use the Contact Support option in the PRTG web interface instead.

Name

Enter your name.

Email

Enter a valid email address. You can provide any of your email addresses, but we recommend that you use the email address of your PRTG account, which PRTG enters by default.

Ticket No.

This field is optional. If you have already opened a ticket with Paessler Support, provide the ticket number here. Your files are then automatically associated with your ticket.

Enter the ticket number starting with PAE followed by four or more digits, for example, PAE12345. If you do not have a ticket number, leave this field empty.
