Subject: [Ironic] A question about getting IPMI data

Hi, all,
As the summit session https://etherpad.openstack.org/p/icehouse-summit-ceilometer-hardware-sensors said, ironic will expose IPMI data to ceilometer, but I have a couple questions here.

1.       What kind of IPMI data will be collected? I assume that power, temperature or other sensor data is needed, right?

2.       How do we get all these data?

IIUC, ironic did not involve too much about IPMI for now, only used ipmitool and pyghmi module.
Using IPMItool to execute command and parsing the output is easy to understand. But seems not a good way for me. The pyghmi only supports out-of-band(net-payload) now. So, I am wondering if we can extend the function of pyghmi to provide more interfaces?
Be specifically, I think pyghmi can provide in-band IPMI interface including IPMB or system interface etc. and allowed to get IPMI data in the OS.

Is all this make sense to you?

Thanks for your response

Best Regards,
