Prtg probes and network outage



Hi. Is there a way for prtg probes to automatically restart after network layer outage? We had a switch outage and when that was resolved the probes were still down and they had to be restarted before they recognised systems was back up.

Hello Ben

Thank you for contacting PRTG support.

Unfortunately, there is no option in PRTG to restart the probe after the switch network outage.

If the connections between the PRTG core server and a probe fail for any reason (for example, restarting the PRTG core server system), the probe continues to monitor and stores the results. During a connection loss, a buffer stores a maximum of 500,000 sensor results in the RAM of the remote probe system (up to 50 - 200 MB). This means that for 100 sensors with a 1-minute scanning interval, the probe can buffer the monitoring results of up to 3 days (or 52 minutes for 10,000 sensors with a 1-minute scanning interval). The probe automatically reconnects to the PRTG core server as soon as it is available again and transmits all monitoring results that it gathered during the connection loss.

You may create a script that can perform this action, however, that should be so by 3rd party tools outside of PRTG support.
