Remote probe as a gateway

We are investigating if PRTG is suitable for us. We are external sysadmins for different companies (SMB) and every remote network has like 5-7 virtual servers which has to be monitored.

Is it prossible to install 1 remote probe on a remote virtual machine and let the probe scan its internal segment to add member servers through WMI? Or is it mandatory to install a remote probe on every external virtual server? I searched the FAQ etc, but did not find any similar questions.

Thank u for your time in advance

For most of the errors that you see for WMI, we have an article here for help troubleshooting. Also, you can download our WMI Tester to see if you are having issues connecting from that server to the other via WMI.

If the sensor is created on the Remote probe, it will be the one querying the other server for WMI requests.

The Remote Probes can be used as remote scanners for multiple other servers. As long as there is connectivity between the Core Server and the Remote Probe and the Remote Probe and the devices that are being monitored, the Remote Probe will scan for the sensors that you set up on it and then relay the data back to the Core for graphing and display.

With the Remote Probe you can use any of the sensors that we have available. More info can be found here

Hey Greg, thank u for your answer. When i try to add a device under the group of the remote probe, it cannot connect to the WMI. I do think PRTG tries to connect from the core server to the member server on a external network, instead of connecting to the remote server through the remote probe (the connection between the remote probe and the member server are not restricted by firewall) It gives the error: Port Error : RPC Server not accessible. - Host: INTERNALADRESS, User: USER, Password: **, Domain: ntlmdomain:DOMAIN

Am I doing something wrong? How can I be sure the WMI connection is initiated from the remote probe? (there doesn't seem te be a option for that??)
