Ps & top different output
 

CPU usage: PS versus TOP - Different output
CPU usage: PS versus TOP - Different output

Hi

When monitoring a Linux environment with PS command, reported CPU & memory value for a certain process differs, sometimes greatly, from the value seen in TOP.

I understood this is not a bug, they report different data.
I can't understand the nature of this difference.

My Question: Can someone explain it in simple manner, or alternativly provide a link to such documentation.

it was discussed several times also here, at LQ, so please look at the links to Similar threads (bottom of this page)
