This is a very useful example!  I guess that you have also defined 
EnergyIPMIUsername and EnergyIPMIPassword in acct_gather.conf?  How is the 
EnergyIPMIPassword protected from normal users if the 
/etc/slurm/acct_gather.conf file exists?

An EnergyIPMIFrequency of 10 seconds sounds like it could put a high load 
on the BMC and the server?

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?

Thanks,
Ole
