How to check in the CLI that the configuration is OK and what are the main options for?​
Once the plugin is installed, log into your Centreon Poller CLI using the
centreon-engine user account (su - centreon-engine) and test the Plugin by
running the following command:
/usr/lib/centreon/plugins//centreon_asterisk_snmp.pl \
    --plugin=apps::voip::asterisk::snmp::plugin \
    --mode=channel-usage \
    --hostname='10.0.0.1' \
    --snmp-version='2c' \
    --snmp-community='my-snmp-community' \
    --warning-channels-active='' \
    --critical-channels-active='' \
    --warning-calls-active='100' \
    --critical-calls-active='200' \
    --warning-calls-count='' \
    --critical-calls-count='' \
    --use-new-perfdata 
The expected command output is shown below:
OK: channels active: 54 calls active: 73 calls count: 746 | 'channels.active.count'=54;;;0; 'calls.active.count'=73;0:100;0:200;0; 'calls.processed.count'=746;;;0; 
This command would trigger a WARNING alarm if the number of active calls is
reported as over 100 (--warning-calls-active='100') and a CRITICAL alarm if
over 200than 50% (--critical-calls-active='200').
All available options for a given mode can be displayed by adding the
--help parameter to the command:
/usr/lib/centreon/plugins//centreon_asterisk_snmp.pl \
    --plugin=apps::voip::asterisk::snmp::plugin \
    --mode=channel-usage \
    --help
All available options for a given mode can be displayed by adding the
--list-mode parameter to the command:
/usr/lib/centreon/plugins//centreon_asterisk_snmp.pl \
    --plugin=apps::voip::asterisk::snmp::plugin \
    --list-mode
