在IntelliJ WebStorm中分析node.js

Question

The IntelliJ V8 CPU and Memory Profiling page describes how to run V8. I get the following when selecting Run from within WebStorm:

   /usr/local/bin/node . --prof --logfile=v8-3-14-16_10-52-54-AM-0.log --log-timer-events
   Web server listening at: http://0.0.0.0:3000
   Browse your REST API at http://0.0.0.0:3000/explorer

Which all seems fine. Then when I select stop ... I get

   Process finished with exit code 130

and WebStorm complains

  "No V8 log files found". 

Is there some step that I am missing to get to the log files?

Answer 1

Node.js profiler requires application main file being passed AFTER profiler arguments, and you are passing '.' BEFORE. Please try changing your command line accordingly ( /usr/local/bin/node --prof --logfile=v8-3-14-16_10-52-54-AM-0.log --log-timer-events . , or /usr/local/bin/node --prof --logfile=v8-3-14-16_10-52-54-AM-0.log --log-timer-events index.js , or whatever your server main file name is)
