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's CLI using the centreon-engine user account (su - centreon-engine) and test the plugin by running the following command:

$CENTREONPLUGINS$/centreon_hp_storeonce4_restapi.pl \
    --plugin=storage::hp::storeonce::4::restapi::plugin \
    --mode=stores \
    --hostname='10.0.0.1' \
    --port='443' \
    --proto='https' \
    --api-username='my-username' \
    --api-password='my-password' \
    --verbose

The expected command output is shown below:

OK: All catalyst stores are ok | 'stores.detected.count'=3;;;0; 'Catalyst01#store.disk.space.usage.bytes'=1838969531121B;;;0; 'Catalyst01#store.user.space.usage.bytes'=62700600887099B;;;0; 'Catalyst01#store.deduplication.ratio.count'=34.00;;;0; 'Catalyst02#store.disk.space.usage.bytes'=50306416657426B;;;0; 'Catalyst02#store.user.space.usage.bytes'=1793362240355355B;;;0; 'Catalyst02#store.deduplication.ratio.count'=35.60;;;0; 'Catalyst03#store.disk.space.usage.bytes'=21192464324702B;;;0; 'Catalyst03#store.user.space.usage.bytes'=540818386772559B;;;0; 'Catalyst03#store.deduplication.ratio.count'=25.50;;;0;
checking catalyst store 'Catalyst01'
    health: ok
    disk space used: 1.67TB, user space used: 57.03TB
    deduplication ratio: 34.00
checking catalyst store 'Catalyst02'
    health: ok
    disk space used: 45.75TB, user space used: 1631.05TB
