Would you be able to give more detail on exactly what type of file is sent from the probe to the core server? One of our probes is on a very high security network and I cant get the firewall flows approved withought this kind of detailed information.

I do not have a concise list of the whole communication for you, but I can say this:

  • The connection is a TCP connection initiated by the probe
  • The data is transferred securely using SSL3.0/TLS encryption
  • The core sends monitoring "jobs" to the probe, including sensor type, IPs, target DNS names, sensor configuration, passwords
  • The probe sends back monitoring results for each sensor for every interval
  • During sensor creation and auto discovery so called "meta requests" are used to scan network devices for available sensor points
  • When a new version of PRTG is installed the installer EXE for the remote probe is transferred so the probe can be updated

Plus various other communications that keep everything running (including keep-alive and heartbeat packets).
