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:

/usr/lib/centreon/plugins//centreon_generic_snmp.pl \
--plugin=apps::protocols::snmp::plugin \
--mode=string-value \
--hostname=10.0.0.1 \
--snmp-community='my-snmp-community' \

--oid='' \
--format-ok='' \
--format-warning='' \
--format-critical='' \
--format-unknown='' \
--warning-regexp= \

The expected command output is shown below:
