This is a very useful example! I guess that you have also defined
EnergyIPMIUsername and EnergyIPMIPassword in acct_gather.conf? How
is the

it talks to the BMC via to OS, so no password/user required.
Ah, of course, the slurmd on your nodes can do local IPMI commands :-)
An EnergyIPMIFrequency of 10 seconds sounds like it could put a high
load
on the BMC and the server?
that might be my problem - I haven't checked that.
Maybe this could be a problem. It's anyway better not to have "OS jitter"
in HPC compute nodes by having system tasks executing too frequently.
I have never tested IPMI DCMI_ENHANCED commands. Do you have some
FreeIMPI commands which can be used to verify the basic IPMI
DCMI_ENHANCED
functionality?
I checked the spec sheet of our BMC which suggested that it should be
able to do DCMI_ENHANCED
That's good to know. Our servers from Huawei don't seem to support
DCMI_ENHANCED.
The following ipmitool command works locally on a node, but I can't figure
out the corresponding command to use with FreeIPMI.
# ipmitool dcmi power reading
Instantaneous power reading: 689 Watts
Minimum during sampling period: 19 Watts
Maximum during sampling period: 905 Watts
Average power reading over sample period: 682 Watts
IPMI timestamp: Wed Aug 30 09:35:28 2023
Sampling period: 00000001 Seconds.
Power reading state is: activated
Best regards,
Ole
