Technical Tip: Monitor secondary unit power supply in HA configuration

This article describes how to monitor secondary unit power supply in HA configuration

It is possible to monitor the secondary power supply in a HA (high availability) configuration.

An OID is looked for to check the power supply via SNMP on both cluster devices.

1. Make sure to have the ha-management interface configured. It is necessary to enable ha-direct in the SNMP setting as explained here:

   2. It is possible to use traps to monitor the power supply:

config system snmp community
    edit xxx

        Set name yyy
        set events (...) power-supply-failure (...)
    end

If there should be an issue with the power supply now in any of the cluster units, a notification will appear if traps are enabled.

Above commands have been tested with 6.4.12, 7.0.12, 7.2.5, and 7.4.0 versions.
