Embed v8-profiler into image #34

Open Unitech opened 7 years ago

Unitech commented 7 years ago

@simonepri what do you about adding v8-profiler module (via pm2 install v8-profiler) by default? It would allow to snapshot memory and run cpu profiling when needed

simonepri commented 7 years ago

Could you describe me an use scenario?

Unitech commented 7 years ago

If the v8-profiler is present in the container, PM2 allows to trigger heapdump and cpu profiling, that is a nice have to inspect what is going on in case of bad behaviors

Unitech commented 6 years ago

it does not work currently to RUN pm2 install profiler on alpine image because python & stuff are missing

How pm2 install profiler works? It runs npm install v8-profiler ?

Unitech commented 6 years ago

Yes exactly and it also auto inject the profiler into the source code of the user allowing to retrieve heapdump/cpuprofile
