On a probe's overview page, click the Settings tab to change settings.
You can add additional remote probes to your setup to extend your monitoring to networks that are not directly reachable by your PRTG core installation or cluster.
See section Add Remote Probe for more details.
The following settings are available in the Settings tab of every probe. Because you may not need all of these for every probe, just regard the settings you really need and ignore the others.
Enter a meaningful name to identify the probe. The name will be shown by default in the device tree and in all alarms.
Choose if monitoring for this probe is started or paused.
Paused: Pause monitoring for this probe. All sensors on all devices on this probe will be paused until this setting is changed again.
Select a priority for the probe. This setting determines where the probe will be placed in list views. Top priority will be at the top of a list. You can choose from one star (low priority) to five stars (top priority).
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 PRTG will use for outgoing monitoring requests of certain sensor types.
This setting will be used for sensors that use the following connection types: HTTP, DNS, FTP, IMAP, POP3, Port, Remote Desktop, SMTP, and SNMP.
The setting is valid for all monitoring requests sent from this PRTG probe.
This setting is useful for devices that expect a certain IP address when queried.
Default setting is auto. PRTG will select an IP address automatically.
This feature does not support all sensor types for technical reasons.
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.
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.
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.
Probe sends data only to primary master node: The probe connects only to the primary master node. You are not able to review monitoring data on failover nodes. Consider choosing this option if you have bandwidth limitations in your network or if the probe cannot access your failover node(s).
Probe sends data to all cluster nodes: This is the default option. The probe connects to all nodes in your cluster and sends monitoring data to the failover node(s) in addition to the primary master. The probe is visible on all your nodes as soon as it connects automatically to the correct IP addresses and ports of the failover nodes. If your master node fails, you can still see monitoring data of this probe.
PRTG will not notify you if a remote probe is disconnected from a cluster node. Please check explicitly on a cluster node if your remote probes are connected (for example, via the device tree in the PRTG web interface on a cluster node).
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 is running. 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): We recommend this setting, although it is not set by default. Enter a schedule below. We recommend that you restart Windows servers once a month for best performance.
Once per week: Select a day of the week and a time below.
Once per month (recommended): Select a day of the month and a time below.
You can only see this setting if you selected a schedule option above. Select a specific day of the week (Monday to Sunday) or month (1st to 30th or 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.
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.
You can only see this setting if you selected a schedule option above. Select the time of day when PRTG will perform the restart.
You will 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 up to 30 minutes from the settings you enter here.
