Enabling hardware metrics in Ceilometer

Hi,

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

The documentation here - http://docs.openstack.org/developer/c... - 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?

Thanks!

-Vivek

In your answer, the 3rd point you mention 'meter_sink'. Here is my configuration:

- name: meter_sink
  transformers:
  publishers:
      - rpc://

Should I change it to?

 - name: meter_sink
          meter: "*"
          transformers:
          publishers:
              - notifier://?per_meter_topic=1

And then restart the Ceilometer services on the compute node?

yes, you can use "*“ to match all metrics this should include the hardware metrics, restart service cannot be avoided, for the ceilometer will read the pipeline.yaml only once when service is started.
