SNMP configured for Power Supply but alerts not receiving

The PSU OID - sysHealthPowerSupplyStatus is of the type ACCESSIBLE_FOR_NOTIFY.

OIDs of this type cannot be explicitly polled by an SNMP Manager (by performing SNMP GET, GETNEXT, etc.). They are sent in the form of varbinds only when NS generates a trap.

As documented in the https://developer-docs.netscaler.com/en-us/adc-snmp-oid-reference/current-release.html, ; section of the OID Reference Guide, the PSU OIDs are used in the following traps –

    powerSupplyFailed

OID:1.3.6.1.4.1.5951.1.1.0.82

This trap is sent when power supply has failed or disconnected from the system Varbinds sent in the trap message - sysHealthCounterName , sysHealthCounterValue , sysHealthPowerSupplyStatus , sysIpAddress To receive this trap enable snmp alarm POWER-SUPPLY-FAILURE
powerSupplyNormal

OID:1.3.6.1.4.1.5951.1.1.0.83

This trap is sent when power supply status returned back to normal Varbinds sent in the trap message - sysHealthCounterName , sysHealthCounterValue , sysHealthPowerSupplyStatus , sysIpAddress To receive this trap enable snmp alarm POWER-SUPPLY-FAILURE
