Re: power server power consumption problem

From a peer..     Rafael Peria de Sene...

At Unicamp we developed a power monitor based on IPMI output to monitor our
Minsky usage.

Take a look at http://177.220.10.134/powergraph

I use ipmitool measuring power server power consumption, getting the

following results without total power consumption as the following picture,
do I add all power values as total power consumption? I am eager to receive
someone's replay??Thanks?

The total system power is already aggregates as provided under ipmi
dcmi command.

You can read it like:

Inband: (within system)

root@ubuntu:~# ipmitool dcmi power reading

    Instantaneous power reading:                   485 Watts
    Minimum during sampling period:                485 Watts
    Maximum during sampling period:                486 Watts
    Average power reading over sample period:      485 Watts
    IPMI timestamp:                           Wed Jun  7 15:53:08 2017
    Sampling period:                          00000010 Seconds.
    Power reading state is:                   activated

Out-of-band: (Over BMC network)

You do get component power consumption from IPMI SDR, you can get
those from inband or out-of-band. But you need not manually add it up.
On-Chip-Controller (OCC) does the power aggregation already and
exports it through DCMI power reading.
