ipmitool dcmi power reading

为什么这个工具存在

因为你可能自己在问：“我如何获取我的功耗数据”?

• https://serverfault.com/questions/389224/power-usage-via-ipmi-or-bios-or

所以你似乎有两个选择

• 使用racadm：(https://serverfault.com/a/1070451/336084)
• 使用ipmitool：(https://serverfault.com/a/1141974/336084) - (https://wiki.evolix.org/HowtoIPMI)

我使用了racadm方法多年，我发现它很慢，有时它不起作用，因为一个iDRAC会话是打开的。然后我使用了ipmitool，它做得很好，但需要解析文本输出。

所以，我首先用相同的文本输出编写了相同的工具，并且它工作得很好。原始的C代码可以在这里找到：ipmitool 1.8.19

特别感谢ipmi-rs库，使得这一切成为可能。
