Because you are asking yourself "how do I get my power consumption numbers" ?
Internet links:
- https://serverfault.com/questions/736068/how-do-i-get-the-power-consumption-of-a-dell-poweredge-server-on-the-cli
- https://serverfault.com/questions/389224/power-usage-via-ipmi-or-bios-or
So you seem to have two options:
- Using racadm: (https://serverfault.com/a/1070451/336084)
- Using ipmitool: (https://serverfault.com/a/1141974/336084) - (https://wiki.evolix.org/HowtoIPMI)
I used the racadm method for years, and I find it slow and sometimes it does not work because an iDRAC session is open. Then I used ipmitool and it did great, but had text output I needed to parse.
So I first wrote the same tool with the same text output and it worked. The original C code can be found here: ipmitool 1.8.19
Special thanks to the library ipmi-rs that made this possible.
