[Nagiosplug-devel] Help needed with simple BASH plugin - Nagiosgetting (null)

[Alan Johnson]

I've even tried hard-coding the host's IP address in the script so that no arguments are needed, but same problem.

Here is the setup of the command in my custom commands file:

define command {
	command_name    check_s3
	command_line    $USER1$/check_s3 $HOSTADDRESS$
}

I am assuming that $HOSTADDRESS$ is being parsed to the script and being used as $1 in the "nc" line

And the service in the host's config file:

define service{
        use				generic-service         ; Name of service template to use
        host_name			host02
        service_description		S3SYNC
        check_command			check_s3
        notification_options		c,r
        notification_interval		240
        notification_period		24x7
        max_check_attempts		3
        check_interval			5
        retry_interval			1
        contact_groups			admins,lautus
        }
