Eltek eNexus device configuration​

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

Network flow​

The Centreon Poller must be able to reach the SNMP port (UDP/161) of the Eltek eNexus device.


  1. Install the Eltek eNexus SNMP Centreon Plugin on every poller expected to monitor Eltek eNexus devices:
yum install centreon-plugin-Hardware-Devices-Eltek-Enexus-Snmp
  1. Install the monitoring templates from the Centreon Monitoring Connector on the Configuration > Monitoring Connector Manager page


When creating an host, fill the 'SNMP Community' and 'SNMP Version' fields to match the device configuration.

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

SNMPEXTRAOPTIONSConfigure your own SNMPv3 credentials combo


How can I test the Plugin and what do the main parameters stand for ?​

Once the Centreon plugin installed, you can test it directly on the Centreon Poller by logging into the CLI with the centreon-engine user:

/usr/lib/centreon/plugins/ \
--plugin=hardware::devices::eltek::enexus::snmp::plugin \
--mode=battery \
--hostname= \
--snmp-version='2c' \
--snmp-community='public' \

The command above checks the battery status (--mode=battery) of an Eltek eNexus device. The device's IP address is (--hostname=, SNMP version 2 is used and the device's SNMP community is public (--snmp-community='public').

You can display all modes available for the Plugin using the --list-mode parameter as in the command below:

/usr/lib/centreon/plugins/ \
--plugin=hardware::devices::eltek::enexus::snmp::plugin \

You can display options of a specific mode by using the --help flag. Here is an example to display systems mode parameters:

/usr/lib/centreon/plugins/ \
--plugin=hardware::devices::eltek::enexus::snmp::plugin \
--mode=battery \

UNKNOWN: SNMP GET Request : Timeout​

This message generally means that you are not using the right SNMP version or community. It could also indicate that a third-party device like a firewall is blocking the SNMP UDP/161 request.

UNKNOWN: SNMP GET Request : Cant get a single value.​

This error message can refer to the following issues:

  • the Eltek eNexus device doesn't support the MIB used by the Plugin
  • the targeted SNMP OID cannot be fetched because of insufficient privileges on the device
