[SOLVED] check_http failing to compile regex

[tgriep]

Try changing the command and service check like the following and see if it works for you.

Code: Select all

define command{
        command_name    check_https_uri_regex
        command_line    $USER1$/check_http -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -t 4 -u $ARG3$ -r $ARG4$ --ssl
        }
      
      
define service {
        use                     generic-service
        host_name               $HOSTNAME$
        servicegroups           SomeServiceaGroup
        service_description     Some Description
        check_command           check_https_uri_regex!3!5!'/api/assort/failed'!'\[\]'!
}

I had to set it up this way for it to work on mine:

Code: Select all

define command{
        command_name    check_https_uri_regex
        command_line    $USER1$/check_http -H $HOSTADDRESS$ -w $ARG1$ -c $ARG2$ -t 4 -u $ARG3$ -r '$ARG4$' --ssl
        }

define service {
        use                     generic-service
        host_name               $HOSTNAME$
        servicegroups           SomeServiceaGroup
        service_description     Some Description
        check_command           check_https_uri_regex!3!5!/api/assort/failed!'\\[\\]'!
}

I've tried all these options. None of them seem to work. I either get a critical for no matches when the service certainly responds [], or the same compilation error.

What version of check_http are you using?

Code: Select all

/usr/local/nagios/libexec/check_http --version

I ask because that is our normal plugin path, but you seem to also use ~/development/nagios-plugins/check_http and /usr/local/nagios/production/libexec/check_http. Have you been modifying the code at all?

[northwood128]

That's just the path our our Nagios installation and my personal workplace. It haven't been messing up with the check.

Code: Select all

$ ../nagios-plugins/check_http --version
check_http v1.4.15 (nagios-plugins 1.4.15)

Could you try the latest version of the Plugins?

https://github.com/nagios-plugins/nagios-plugins/

The bug might still exist but I want to make sure we're fixing the latest code if we do have to make a patch.

Please update your plugins as indicated by tmcdonald.

I got this working on a test Nagios XI box of my own, with the following configurations in place:

command:

Code: Select all

define command {
       command_name                             check_xi_host_http
       command_line                             $USER1$/check_http -H $HOSTADDRESS$ $ARG1$
}

service:

Code: Select all

define service {
        host_name                       insightfulcowthoughts.com
        service_description             check HTTP for []
        use                             generic-service
        check_command                   check_xi_service_http!-r "\[\]"!!!!!!!
        notifications_enabled           1
        register                        1
        }

After upgrading your plugins, give the above a shot. If you need define a URL, I can verify that ssax's solution worked properly for me as well.

[northwood128]

thanks guys! I have an outdated version. I'll evaluate the compatibility of the new plugin with our monitoring server and release a new rpm that includes the new version of the plugin.

$ ./check_http --version
check_http v2.0.3.2.g472e (nagios-plugins 2.0.3)

[jolson]

Sounds good, let us know how it works out.

Updating the plugin worked! Sorry for the delay!
