Nagios Support Forum

Go for it, one of the github reports already says it's got a fix in 2.2.2, so I'll wait for it to drop.

And I just missed it when looking for another report on this. It looks like this is already reported in github at check_http: -C broken after update to 2.2.1 and check_http: Breaking change to -C: Certificate check should not check URL

With check_http in 2.2.1, compiled from source, when specifying the '-C ##' option to check a certificate expiration, it now appears to do an http request for content. Relevant excerpt from the check_http man page : -C, --certificate=INTEGER[,INTEGER] Minimum number of days a certificate has to be v...

Try using the --sni switch:

I think the plugin you are using isn't setup to pass host header info. I looked at the script and it has a -a option that is supposed to be for sending extra info like the host header. You might be able to modify the check plugin to do that (look at the openssl open line there in the perl script) Ho...

command_line $USER1$/check_ssh -H $HOSTADDRESS$ Your command definition is probably what's wrong; check_ssh doesn't use -H. Usage: check_ssh [-46] [-t <timeout>] [-r <remote version>] [-p <port>] <host> Use command_line $USER1$/check_ssh $HOSTADDRESS$ or if you want to get fancy and be able to send...

I don't think I've seen the conditions described here in nagios 4 (and possibly not in nagios 3). On all of my nagios servers, when a host is down, service notifications are suppressed (with a few odd exceptions, but they are definitely not the norm). This is the relevant doc excerpt from http://nag...

Is the goal just to catch hosts not added to a hostgroup so you can spot them? If so, you could do it with a service definition since with those you *can* send it a * for the host_name and then do a set of exceptions with hostgroups. Something like this would use check_dummy for all hosts not define...

I'm not sure it changes your points at all, but the warning/unknown states on a host alive count towards whether a host is flapping. I could see the warning/unknown values still being wanted for a host alive check to try to pickup those states (so a host that goes ok-warn-ok-warn-ok-warn and never a...

This is not a solution, but does the behavior change if you put a + sign in front of the contact group name in the host and service definition? ( this should give it an additive inheritance with anything defined above it in a template). I think what'd help the most at this point is to pick a specifi...
