= Configuring screen to display multiple dstat for different systems

Here is an example of how I monitor 5 nodes in a cluster with a minimum
of effort using screen:

Put the following content in a file called screenrc-5nodes:

----
startup_message off
defwrap off
split
split
split
split
screen -t node01 1 ssh -t 172.17.0.211 'dstat -cdnyp --tcp --udp -l -D lores,hires -N bond0,eth0,eth2,eth3 10'
focus down
screen -t node02 2 ssh -t 172.17.0.212 'dstat -cdnyp --tcp --udp -l -D lores,hires -N bond0,eth0,eth2,eth3 10'
focus down
screen -t node03 3 ssh -t 172.17.0.213 'dstat -cdnyp --tcp --udp -l -D lores,hires -N bond0,eth0,eth2,eth3 10'
focus down
screen -t node04 4 ssh -t 172.17.0.214 'dstat -cdnyp --tcp --udp -l -D lores,hires -N bond0,eth0,eth2,eth3 10'
focus down
screen -t node05 5 ssh -t 172.17.0.215 'dstat -cdnyp --tcp --udp -l -D lores,hires -N bond0,eth0,eth2,eth3 10'
----

Then set the environment variable to tell screen to use this config-file
for the next screen.

----
SCREENRC='screenrc-5nodes' screen
----

If you want to get out of this screen and end all dstats, the easiest way
is to kill first all regions and then end each dstat. You can do this by:

----
ctrl-a X
----

Do that 5 times, and then quit each dstat by pressing:

----
ctrl-c
----

5 times.
