How to check in the CLI that the configuration is OK and what are the main options for ?

Once the plugin installed, log into your Centreon Poller CLI using the centreon-engine user account and test the Plugin by running the following command:

/usr/lib/centreon/plugins//centreon_php_apc_web.pl \
    --plugin=apps::php::apc::web::plugin \
    --mode=memory \
    --hostname=10.0.0.1 \
    --proto='http' \
    --port='80' \
    --urlpath='/apc.php' \
    --warning-used='80' \
    --critical-used='90' \
    --warning-fragmentation='' \
    --critical-fragmentation='' \
    --use-new-perfdata 

Expected command output is shown below:

OK : Memory Usage Total: 985.22 MB Used: 500.68 MB (50.82%) Free: 484.54 MB (49.18%) Memory Fragmentation: 10% | 'memory.usage.bytes'=525000704B;80;90;0;1033080832 'memory.fragmentation.percentage'=10%;;;0;100 

This command would trigger a WARNING alarm if the memory usage is reported as over 80% (--warning-used='80') and a CRITICAL alarm if over than 90% (--critical-used='90').

All available options for a given mode can be displayed by adding the --help parameter to the command:

/usr/lib/centreon/plugins//centreon_php_apc_web.pl \
    --plugin=apps::php::apc::web::plugin \
    --mode=memory \
    --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_php_apc_web.pl \
    --plugin=apps::php::apc::web::plugin \
    --list-mode
