Nagios Support Forum

Hi,

Can Nagios help me in monitoring vpn tunnels on network devices and what type of information I can get while monitoring the same and can I monitor things like application firewall and hardware firewalls using nagios.

Thanks,
Manish Kumar

I'd start by seeing what plugins already exist that do what you need.

Here's the Core manual for a reference if you need any setup details.
