Enabling hardware metrics in Ceilometer


Is there any documentation which specifies the procedure to enable hardware metrics for OpenStack hosts?

The documentation here - - says 'snmpd agent should be running on the host from which the metrics are gathered'.

I see that snmpd is running on the host and when I do a snmpwalk from the compute node, I get a valid response describing the host.

snmpwalk -v 2c -c public <Node_IP>

Is there anything else that needs to be configured on the compute node to get these hardware.* metrics?
