Enabling SNMP on HP iLO4

Version 4 of the HP iLO4 (HP Integrated Lights-Out) system fully implements the SNMP protocol. This makes it possible to directly query and retrieve information from the Proliant server. By simply activating SNMP, you can retrieve :

The status of the RAID array
Controller card status
Disk status
SMART data for each disk
Various temperatures (system, ambient, CPU, etc)
Power supply and fan status
Model and serial numbers

Enable SNMP

Go to the administration interface of your Proliant G8 and above (here: an HP320e). Click on “Administration” and then on “Access Setting” in the drop-down menu.

Check that “SNMP Access” is set to “Enabled” and that the “SNMP Port” is set to 161, then click “Apply”.

Then click on 'Management' in the 'Administration' section.

Enter the SNMP community, in the example it will be “public”, and click on “Apply”.

iLO is now accessible via SNMP on the Esia platform. The associated plugins are :

GESA_ILO4_SNMP_TEMP: temperature sensor
GESA_ILO4_SNMP_DISKHEALTH: SMART status, controller, disk and RAID array status
GESA_ILO4_SNMP_SYSTEMHEALTH: fan, CPU and power supply status

You can add these services via your usual management interface.
