  • Thanks, that is very useful! I assume you need to install some packages to get that to work. Do you happen to know which packages? – Onnonymous Aug 06 '20 at 08:32

This can be done with the Supermicro SMCIPMITool; see the "Input Power".

[root@mgmt ~/SMCIPMITool/SMCIPMITool_2.11.0_bundleJRE_Linux_x64_20140704]# ./SMCIPMITool supermicro-ipmi-interface ADMIN password pminfo

[edit]

If you get a "Can't login to [ip-address]" while the password is correct, try this: IPMI web interface -> Miscellaneous -> SMC RAKP -> Disable

  • That doesn't quite give you the power usage, you need to do this: ./SMCIPMITool IP_ADDR ADMIN password dcmi powerStatus Instantaneous power reading | 237W Minimum during sampling period | 10W Maximum during sampling period | 509W Average during sampling period | 300W IPMI timestamp | 2019/11/26 19:03:01 Sampling period | 1477117856 Milliseconds Power reading state | Activated – Mick T Nov 26 '19 at 19:05

for FreeBSD:

pkg install ipmitool
kldload ipmi
