Nagios Support Forum

Good moorning,
I've been time working with Nagios and I have a questions with the check_ping.

The check_ping monitors the rta and package lost in a connection between servers and returns DOWN when it exceeds the arguments.

That isn't correct, because what it means is that I can't by ping to my server, but not to this DOWN.
I have a network problem or another and therefore not to ping.

DOWN is just a host state in Nagios. For most people, a machine that cannot be pinged is a pretty good indicator that it is down. If they are actively blocking pings, the Nagios administrator should know this and choose a different method of checking, such as looking at a service on that machine or attempting a login. In your case, I would set up a dependency from that host to the switch or router it is on, and if the network device goes down you can instead treat all hosts behind it as unreachable instead of down.

Thanks for your reply.
