Chrome V8 profiling log processor
|
|
|
|
|
</h3>
|
|
|
|
|
<p>
|
|
|
|
|
Process V8's profiling information log (sampling profiler tick information)
|
|
|
|
|
in your browser. Particularly useful if you don't have the V8 shell (d8)
|
|
|
|
|
at hand on your system. You still have to run Chrome with the appropriate
|
|
|
|
|
<a href="https://code.google.com/p/v8/wiki/ProfilingChromiumWithV8">
|
|
|
|
|
command line flags</a>
|
|
|
|
|
to produce the profiling log.
|
|
|
|
|
</p>
|
|
|
|
|
<h4>Usage:</h4>
|
|
|
|
|
<p>
|
|
|
|
|
Click on the button and browse to the profiling log file (usually, v8.log).
|
|
|
|
|
Process will start automatically and the output will be visible in the below
|
|
|
|
|
text area.
|
|
|
|
|
</p>
|
|
|
|
|
<h4>Limitations and disclaimer:</h4>
|
|
|
|
|
<p>
|
|
|
|
|
This page offers a subset of the functionalities of the command-line tick
|
|
|
|
|
processor utility in the V8 repository. In particular, this page cannot
|
|
|
|
|
access the command-line utility that provides library symbol information,
|
|
|
|
|
hence the [C++] section of the output stays empty. Also consider that this
|
|
|
|
|
web-based tool is provided only for convenience and quick reference, you
|
|
|
|
|
should refer to the
|
|
|
|
|
<a href="https://code.google.com/p/v8/wiki/V8Profiler">
|
|
|
|
|
command-line</a>
|
|
|
|
|
version for full output.
