Descrizione

Poor man's profiling of a JVM:

$ for i in `seq 1 300`;do jstack $(pgrep java) > $i.jstack;sleep 1;done;zip profile.zip *.jstack;rm *.jstack

...and then uploading profile.zip. I'm tired of opening up traffic for profiling to production and/or building lots of tooling around it. jstack (and shell) is always availalable.
