Is there a cross-machine top -u myUsername command that I can see my processes (along with their CPU usages) across all the specified machines?

If not, I have an idea in mind. I can write a script that SSH into a machine, top -u myUsername, then SSH into the next machine, top -u myUsername again, ..., finally compile everything and display on my current logged in machine. I am not sure how I can "return" the top results from a secondary session to my current session.

Is there a better or more elegant way?

Try something like this:

for i in $(cat server_list); do ssh $i 'hostname;top -b -n1 -u myUsername'; done >> mytop.out

  • Thanks! Hmmm, I would like something dynamic, like top itself. Keeping refreshing in a terminal window. Commented Mar 19, 2017 at 21:10
