how to get message from disconnected part of network

We are supporting customer with central datacenter and plenty production nodes (factories) connected via WAN. Internal setup of each node/factory is totally independent and IT in factory is able to work when WAN connection is not working for the factory. From monitoring perspective we have central PRTG server in datacenter and remote probes in local nodes (currently we are adding second probe for each node). WAN and local LANs are operated by third party. When WAN is not working - we cannot see status of local node - means we cannot distinguish between "just WAN" or "factory down" situation. As we are responsible for customer application operation, it would be nice to be able to get positive (or negative) alert from disconnected island (e.g via SMS) - like "application works" or at minimum "database server is visible from app server" . If I understand PRTG architecture well - the remote probe cannot do such work. Also clustering over WAN looks like not good solution - we have 14 factory nodes there. What solution would you recommend ?

Hey jsolnick,

Actually (as you already assumed) this is not possible as all message will be send out from the Core Server only.

However, in case that the connection between Core Server and Remote Probe is down, the Remote Probe continues monitoring its devices in the LAN. As soon as the connection is back up, the Remote Probes sends all its monitoring data to the Core Server.

To check if the disconnection is related to a WAN-issue or a problem on the Remote Probe itself, we recommend to deploy devices on your local probe (each for every Remote Probe), using the IPs of the Remote Probes and to deploy a PING-sensor on these devices.

That way you will see if the WAN-connection is down or if it is related to the Remote Probe.

Best regards,
Sven
