Advantages and disadvantages using Remote Probes



Hello PRTG-Team,

which advantages or disadvantages do we have from using remote probes ? At the moment we have a cluster with 2 nodes (primary + failover) and several remote probes for monitoring other locations.

We're thinking about removing all remote probes to achieve less hardware costs and decrease the time for adminisration. Are there further advantages or even disadvantages?

Thank you!

Kind Regards Matheus

Dear Matheus,

remote probes can make firewall configuration much easier when you monitor different networks. Only the TCP port 23560 has to be opened in order to communicate with an outside core server. In addition, a remote probe takes some load off the core server, as the probe is doing the actual sensor scan and then just sends the result back.

If you want to monitor a different location without a remote probe, the ports for the according protocols like SNMP, WMI and others have to be opened to the outside. This is usually not recommended.

Hi Arne,

thank you for the information. We don't have any problems regarding to the communication between nodes and probes.

Remote Probes perform the check and send the result to the node (via WAN). Are these packets compressed ? Do i have a less load on the WAN connection, while using remote probes?

Dear Matheus,

in many, but not all cases, the amount of data sent by the probe to the core is less than the actual query would generate. The data is not really compressed, but stripped down to the sensor results actually needed instead of the full dataset the device returned when queried by the sensor.
