How can I measure the power usage of a Dell Poweredge server from the command line interface?

Although most question with this size is VLQ, imho this isn't.– peterhNov 13, 2015 at 9:41

@peterh Would you care to elaborate, so that I may learn to contribute in a better way?– OnnonymousNov 13, 2015 at 13:53

Most review has only a short time to evaluate a post. So, it is much better if your post isn't only valid, but it also seems valid. One of them is if it is enough long, and it has a clear structure. When I ask, I ask always in at least in 3-4 lines, in most cases I try to answer the "Why do you want this to know?" question as well.– peterhNov 13, 2015 at 21:35

1I fail to understand why you think length or format of the question has anything to do with its validity. It's just a simple question, so I don't see a reason to waste any more words on it. I needed to find out this information because next year I need to move 25 PB (yes, petabyte) of storage hardware to another data center. As a preparation, we're checking if the system reported power usages matches the datacenter reported power usage. A Google search did not provide a simple recipe and I spent some time figuring it out, so I decided to provide a recipe to others to be helpful.– OnnonymousNov 13, 2015 at 23:10

I tried to help, if you won't it, then I wish you many luck in the future.– peterhNov 14, 2015 at 19:26

Install the srvadmin-all package and dependencies following these instructions: http://linux.dell.com/repo/hardware/latest/
You may need to log out and in to set the $PATH correctly.
Then:
[root@poweredge ~]# omreport chassis pwrmonitoring

In my case omreport chassis pwrmonitoring was maybe not giving the result I wanted.
