| |
I'm running "top d 0" right now, in an xterm. Nothing much else is happening except one xclock ticks once per second.
The "CPU states" line is interesting:
"user" varies between ~22% and 101% (!) (based on just looking at it) "system" varies between ~22% and 101% "nice" is usually 0%, but occasionally 45% or so for one sample. (that's ok, kswapd is a niced processed, though I don't know why it would be doing anything at all). "idle" switches between 0% and 10%, occasionally showing 0.4%, 9.9% etc.
The "idle" time settles into this state after a couple of minutes. Initially, it is more variable but still in the approximate range 0%-10%.
Some questions arise:
1. 101% is obviously wrong and should never be reported. Is this a "top" thing, or a number reported by the kernel?
2. The idle time shows some interesting jumps. I'd expect 0% all the time. Is this top's calculations again?
