We currently use ManageEngine's Applications Manager 8 to monitor external websites and I am trailing PRTG as a potential replacement. However, I have come across a potential game breaker for us.
We need to monitor these websites from an external source. So although we host the sites, we can't monitor them from within the same network. We have a separate external monitoring setup for this, but PTRG seems to want me to add the server as a device first, then the HTTP sensor on top.
Obviously, as the PTRG server is sat outside the network, I can't monitor the device. Is there a way of setting up HTTP sensors without the need to be able to 'see' the server which hosts them?
Any advice would be appreciated!
