once you have the pid (9067)

ps -p 9067 -o pid=,%mem=,vsz=,%cpu=,command=

EDIT as I just copied the command from question I didn't noticed there was many =, there can be only one = at the end, it is to remove header

ps -p 9067 -o pid,%mem,vsz,%cpu,command
ps -p 9067 -o pid,%mem,vsz,%cpu,command=

man ps for more information

fast way - use grep:

ps -C java -o pid=,%mem=,vsz=,%cpu=,command= |grep S‌​NAPSHOT/conf/engine_‌​logback.xml

enjoy
