Collected metrics & status​

Metric NameUnit


SNMP Configuration​

To use this pack, the SNMP service must be properly configured on your Opengear equipment.

Network flow​

The target server must be reachable from the Centreon poller on the UDP/161 SNMP port.


Monitoring Pack​

If the platform uses an online license, you can skip the package installation instruction below as it is not required to have the pack displayed within the Configuration > Plugin Packs > Manager menu. If the platform uses an offline license, install the package on the central server with the command corresponding to the operating system's package manager:

dnf install centreon-pack-network-opengear-snmp

Whatever the license type (online or offline), install the Opengear SNMP Pack through the Configuration > Plugin Packs > Manager menu.


Since Centreon 22.04, you can benefit from the 'Automatic plugin installation' feature. When this feature is enabled, you can skip the installation part below.

You still have to manually install the plugin on the poller(s) when:

  • Automatic plugin installation is turned off
  • You want to run a discovery job from a poller that doesn't monitor any resource of this kind yet

More information in the Installing the plugin section.

Use the commands below according to your operating system's package manager:

dnf install centreon-plugin-Network-Opengear-Snmp



  • Log into Centreon and add a new host through Configuration > Hosts.
  • Fill the Name, Alias & IP Address/DNS fields according to your Opengear server settings.
  • Apply the Net-Opengear-SNMP-custom template to the host.

When using SNMP v3, use the SNMPEXTRAOPTIONS Macro to add specific authentication parameters. More information in the Troubleshooting SNMP section.

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:

/usr/lib/centreon/plugins/ \
--plugin=network::opengear::snmp::plugin \
--mode=memory \
--hostname='' \
--snmp-version='2c' \

The expected command output is shown below:

OK: Ram Total: 247.75 MB Used (-buffers/cache): 49.95 MB (20.16%) Free: 197.80 MB (79.84%), Buffer: 7.08 MB, Cached: 21.73 MB, Shared: 0.00 B | 'memory.usage.bytes'=52375552B;;;0;259784704 ''=207409152B;;;0;259784704 'memory.usage.percentage'=20.16%;;;0;100 'memory.buffer.bytes'=7421952B;;;0; 'memory.cached.bytes'=22781952B;;;0; 'memory.shared.bytes'=0B;;;0;

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

/usr/lib/centreon/plugins/ \
--plugin=network::opengear::snmp::plugin \
--mode=memory \

All available modes can be displayed by adding the --list-mode parameter to the command:

/usr/lib/centreon/plugins/ \
--plugin=network::opengear::snmp::plugin \
