I need a way to the used memory of a current tmux session. I am not sure if that is even possible. I am using tmux to start multiple minecraft servers I'd like to know each servers memory usage.
I recommend you to run
pgrep server_binary to know the
PID of each instance and then
top -p PIDs to know all
resident memory and
shared memory used by each bash instance.
#know PID of each bash instance > pgrep bash 4301 4420 4426 4432 4438 4444 4450 4456 #list all resources used by each instance > top -p 4301,4420,4426,4432,4438,4444,4450,4456
