Prerequisites
To use this pack, the SNMP service must be properly configured on your Flex System blade server. Lenovo provides an official documentation to achieve this:
- Throught the CMM Web console : https://sysmgt.lenovofiles.com/help/index.jsp?topic=%2Fcom.lenovo.lxci_hwmp_scom.doc%2Fhwmp_enable_snmp_agent
- Throught the CMM Command-Line Interface : https://flexsystem.lenovofiles.com/help/index.jsp?topic=%2Fcom.lenovo.acc.cmm.doc%2Fcli_command_snmp
Network flow
The Lenovo Flex System blade server must be reachable from the Centreon Poller on the UDP/161 SNMP port.

FAQ
How do I run my plugin through the CLI and what do the main parameters stand for ?
Once you've installed the plugin, you can test it logging with centreon-engine user:
/usr/lib/centreon/plugins/centreon_net_lenovo_flexsystem_snmp.pl \
--plugin=network::lenovo::flexsystem::snmp::plugin \
--mode=interfaces --hostname=10.30.2.138 \
--snmp-community='public' \
--snmp-version='2c' \
--add-status \
--add-traffic
Expected command output is shown below:
OK: All interfaces are ok | 'traffic_in_lo'=11723.33b/s;;;0;10000000 'traffic_out_lo'=11723.33b/s;;;0;10000000 'traffic_in_ens192'=14097.70b/s;;;0;10000000000 'traffic_out_ens192'=21796.60b/s;;;0;10000000000
All available modes with the plugin can be displayed with:
/usr/lib/centreon/plugins/centreon_net_lenovo_flexsystem_snmp.pl \
--plugin=network::lenovo::flexsystem::snmp::plugin \
--list-mode
The available options for a mode can be displayed using the --help parameter:
/usr/lib/centreon/plugins/centreon_net_lenovo_flexsystem_snmp.pl \
--plugin=network::lenovo::flexsystem::snmp::plugin \
--mode=interfaces \
--help
UNKNOWN: SNMP GET Request : Timeout
If you get this message, you're probably facing one of theses issues:
- Your SNMP server isn't started or misconfigured
- An external device is blocking your request (firewall, ...)
UNKNOWN: SNMP GET Request : Cant get a single value.
This message generally means that SNMP privileges are not wide enough for the mode/plugin to work properly.
