Check /bin/systemctl status

Project Notes

Feel free to contact me for help, I have another pluigin that was very popular for init.d scripts this is the updated version for systemd.

Options:
-s
-s '/bin/systemctl status ' (required)
This is the script to run, the script is designed to run scripts in the
/bin/systemctl dir (but can run any script) and will call the script with
a 'status' argument. So if you use another script make sure it will
work with /path/script status, example: '/bin/systemctl status nagios4'

-e
This is the "exitstaus" flag, it means check the exit status
code instead of looking for a pattern in the output of the script.

-p 'REGEX'
This is a pattern to look for in the output of the script to confirm it
is running, default is 'active (running)', but not all /bin/systemctl scripts output
(iptables), so you can specify an arbitrary pattern.
All patterns are case insensitive.

-n
This is the "NOT" flag, it means not the -p pattern, so if you want to
make sure the output of the script does NOT contain -p 'REGEX'

-r
This is the "ROOT" flag, it means run as root via sudo. You will need a
line in your /etc/sudoers file like:
nagios ALL=(root) NOPASSWD: /bin/systemctl status *

-o
This is the "SUPPRESS OUTPUT" flag. Some programs have a long output
(like iptables), this flag suppresses that output so it is not printed
as a part of the nagios message.

Simply add this to your command file:
define command {
command_name check_exit_status
command_line $USER1$/check_exit_status.pl -r -s $ARG1$
}

Here is a sample service definition:
define service{
use local-service
host_name (Host Name)
service_description Postfix
check_command check_systemd_status!postfix
}
