Changing "No route to host" error code from Crit to Warn

[KKoovalsky]

Hi!

How can I change error codes of "No route to host" and "Connection refused or timed out" notifications from critical to warning?

Usually, you'll need to write a wrapper script to sit in front of the plugin to handle the logic for if it detects that text.

It might be built in with the plugin, though - which plugin are you using?

I'm using check_ping. Inside check_ping.cfg I have service check_host_alive with this plugin used with -c arg not optional. I tried to call check_ping with -c 101%, but this doesn't work.

Developing custom plugins is really out of scope for support but we can tell you how it works.

Your wrapping plugin needs to sit as a shim between the standard check_ping and Nagios. The custom plugin will execute check_ping and process the data. If it gets text like No route to host or Connection refused or timed out then the custom plugin needs to exit with a return code of 1 instead of 2 as the standard plugin would do.
