for a start, the top command will fail unless you tell it you want to run it in batch mode, as sshd will not provide a valid $TERM variable.
apart form that something along the lines of :
Code:
for serv in host1 host2 host3
do
echo
echo $serv
ssh $serv top -n 1 -b |grep SS |awk '{print $6}'| cut -c 1-4
done
should suffice, once you've ensured that the user running the script has passwordless keys setup.
the parameters to top are
-n 1 run 1 iteration and quit
-b run in batch mode, don't look for a terminal
hello
for serv in s11s s15r s25n
do
echo
echo $serv
ssh $serv top -n 1 -b |grep SS |awk '{print $6}'| cut -c 1-4
done
it works but here is the output
