Ok, here is a scenario: The PRTG is setup, it's talking to multiple agents. Some of the agents are set to run scripts when thresholds are breached.

I guess there are two questions:

1. Can the agent poll the system its on independently since everything has been setup on the server before it went down?

if the above is a YES.

2. Can the agent run the script independently as well?

Hello kusumah,
thank you for your inquiry.

PRTG is agentless, so I'm assuming that when you say "Agent" you're referring to a PRTG Probe, is that assumption correct?

Please be aware that PRTG Probes have a "simple" job, they receive instructions from the Core Server (with monitoring instructions) and perform these. The results are sent back to the PRTG Core Server.

All other PRTG "features" are performed by the Core Server, this includes:

  • Evaluating Monitoring Results, setting sensors up, down, etc.
  • Triggering notifications based on the values received by the probe.
  • Executing the notification scripts.

This means that if a Remote Probe is disconnected it won't be able to deliver the results to the Core Server, hence the values will not be evaluated and there will be no notifications. Even if they were, notifications are always "fired" by the Core Server, never by a Probe.
