Virkram,

The command to switch to total CPU consumption with top running in interactive mode (the usual mode) is ‘I’.
You might enter ‘I’ you will see the difference.

First off, thanks a lot for this useful website – extremely helpful info, commands, tips and tricks.
I discovered, disappointedly though, that the %CPU column is “The percentage of a single CPU usage by the thread/process”. Now, to calculate the average CPU consumption, we need to divide this value by the number of CPUs. Is there a flag or option in “top” to make it show the average CPU consumption across all CPUs? I presume most people look at the column value and usually respond in alarm when a 2 processor machine or 2 core server is running at 100% whereas it is truly only consuming 50% of CPUs.

Hi, nice info. But the thing is, i want this output in the batch mode.
top -n1 b

So how do i get all cpu in this mode? Till now i’ve been quite unsuccessful.
Basically i’ve written a script to capture the TOP output for techsupport. So there, interactive mode is not usefull.

I looked all over for the command to display all CPU’s at once and finally found it,

Im running 2 quad core processors and 64g of ram on a workstation, so I wanted to veryify both quadcores were working as they should be

I tried grep -i core /proc/cpuinfo
the system didnt output anything
It just accepted the command without prompting an error.

Useful information. I didn’t see that you say to press the number 1 until I looked a second time. Thanks.
