We use a simple shell script like the one below. You'd, obviously, have to tweak it somewhat to tell it about the different file names and decide which box to look for which on but you get the basic idea. In our case we are tailing a file at the same location on multiple boxes. This requires ssh authentication via stored keys instead of typing in passwords.
#!/bin/bash
FILE=$1
for box in box1.foo.com box2.foo.com box3.foo.com box4.foo.com; do
ssh $box tail -f $FILE &
done
Regarding Mike Funk's comment about not being able to
kill the tailing with ^C, I store the above in a file called multitails.sh
and appended the following to the end of it. This creates a kill_multitails.sh file
which you run when you're done tailing, and then it deletes itself.
# create a bash script to kill off
# all the tails when you're done
# run kill_multitails.sh when you're finished
echo '#!/bin/sh' > kill_multitails.sh
chmod 755 kill_multitails.sh
echo "$(ps -awx | grep $FILE)" > kill_multitails_ids
perl -pi -e 's/^(\d+).*/kill -9 $1/g' kill_multitails_ids
cat kill_multitails_ids >> kill_multitails.sh
echo "echo 'running ps for it'" >> kill_multitails.sh
echo "ps -awx | grep $FILE" >> kill_multitails.sh
echo "rm kill_multitails.sh" >> kill_multitails.sh
rm kill_multitails_ids
wait
