Adding network devices in icinga

I want to add my network devices in icinga monitoring dashboard.

If somebody added, can I just see the followings for 1 single network device
1.hosts.conf
2.services.conf
command.conf (if using any custom commands)

I think it would help people if you gave at least an indication of what you
mean by “network devices”.

As far as I’m concerned, almost everything is a network device these days, so
it’s not a very clear definition.

What devices in particular are you wanting to monitor, and what is it about
them that you want to monitor?

I have already configured monitoring for Linux/Windows servers successfully in icinga

Now, I am looking to configure monitoring of Routers & switches in icinga,

What I want to montior? well let me see the real examples what router/switches services people are monitoring
