Nagios Support Forum

I have a server that is sitting on a different network.
The plan was to go through https port to monitor the server.
We also have a network engineer that mapped an IP to it.
I tried to use the wizard to add it to Nagios to monitor but to no success.
I was trying to find documentation but only found monitoring the https port available.
Do we have documentation on how to do that? or is this not possible?

What agent are you running on the remote system? Does the agent need to check other servers on the remote node/subnet?

we have the NSclient agents installed,
we want the agent to have the ability to monitor other servers.
We don't want to NAT all the servers/set public IPs for all internal servers

You have a few options , ranging in complexity:
1. Use a vpn/tunnel to gain a route to the full remote subnet.
2. Setup a nagios server in the remote environment and push the results to your XI server.
3. Use nsclient as a proxy server to check other servers on the subnet (very tricky to configure, will make the nsclient configuration file on the nsclient "proxy" server large and unwieldy.
4. Passive checks.

My suggestion is 1 or 4.

if we go route 4, do we set the normal nsclient agents up and select passive checks?
or is there a specific configuration that needs to be done?

I will point you towards the following document:

Please understand that the remote windows systems must be able to route back to the XI server for passive checks to be viable.

for network connectivity, we still need to be able to ping the server from the monitoring server in order to do the passive checks?

No, but you will need to be able to ping the monitoring server from the remote server.
