> Does it show js stack traces? Yes. perf has JIT support. When the Node runtime flag is enabled the app will produce a .map file which contains the memory address and instruction information necessary to fill in the blanks.
> Is it possibly to apply this for a already running app? AFAIK the application must be started with the correct option. Though there may be an API that allows the user to toggle this functionality. If not, then it would be useful to create a ticket upstream to support it. > Without using perf record ? This one confuses me. perf record is what allows you to collect the data necessary to create the flame graph. Unless you use dtrace. Those are the only two options I know of so far. -- Job board: http://jobs.nodejs.org/ New group rules: https://gist.github.com/othiym23/9886289#file-moderation-policy-md Old group rules: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines --- You received this message because you are subscribed to the Google Groups "nodejs" group.
