check_http - respond Critical if the website loads?

[ewolff]

Basically trying to do the opposite of what check_http is used for. Respond OK if the site does not load, but respond Critical if the site responds.

So basically if I get this using check_http

connect to address x.x.x.x and port 80: Connection refused
HTTP CRITICAL - Unable to open TCP socket

I want Nagios to return with OK

I've tried messing with -d -s -e -P -T and --invert-regerx but I think the socket timeout is getting in the way.

Basically I'm looking for a failsafe alert if my ACLs for restricting access to a website get wiped out or disabled.

Hi @ewolff,

Thanks for reaching out.

Have you looked at the negate plugin? It calls another plugin and inverts the value.

Using the Negate Plugin.

Yeah it looks like that will do what I want it to do. I'm testing it from command line and it's throwing the proper codes so I should be able to create a customer check to reference this.

Thanks
