[Nagios-users] Remote monitoring
I am looking for a way to remotely monitor Windows servers. The servers are on a remote network and using network address translation so they are not directly accessible. I saw that Pandora uses an agent on the remote servers to connect via ssh to the main monitoring server and I like that idea, but I have not been able to see any documentation on how to do it with Nagios. In our configuration we cannot alter or open ports on the clients firewalls, but outgoing ssh traffic should not be an issue and I guess the monitoring server should not contact the remote servers. Is there a way to have an agent on a remote Windows servers similarly using ssh to tunnel the traffic? Regards, Paul - This SF.net email is sponsored by: Microsoft Defy all challenges.
