Maybe a little bit OT, In z/OS, you can see if a process has been put to suspended state because some other process is eating cpu and it keeps historical data about it. Is there a way to achive same thing for Linux? I am reading brendangregg's performance book, however I could not see anything related to this so far.

I thing atop [1] is the tool I am looking for. It can keep historical data.

htop shows a T in the state column when the process is suspended or Traced

The “T” stands for “sTopped”.

htop does not keep historical data as far as I know.
