| 127 | + Chrome V8 profiling log processor |
| 128 | +</h3> |
| 129 | +<p> |
| 130 | +Process V8's profiling information log (sampling profiler tick information) |
| 131 | +in your browser. Particularly useful if you don't have the V8 shell (d8) |
| 132 | +at hand on your system. You still have to run Chrome with the appropriate |
| 133 | +<a href="https://code.google.com/p/v8/wiki/ProfilingChromiumWithV8"> |
| 134 | + command line flags</a> |
| 135 | +to produce the profiling log. |
| 136 | +</p> |
| 137 | +<h4>Usage:</h4> |
| 138 | +<p> |
| 139 | +Click on the button and browse to the profiling log file (usually, v8.log). |
| 140 | +Process will start automatically and the output will be visible in the below |
| 141 | +text area. |
| 142 | +</p> |
| 143 | +<h4>Limitations and disclaimer:</h4> |
| 144 | +<p> |
| 145 | +This page offers a subset of the functionalities of the command-line tick |
| 146 | +processor utility in the V8 repository. In particular, this page cannot |
| 147 | +access the command-line utility that provides library symbol information, |
| 148 | +hence the [C++] section of the output stays empty. Also consider that this |
| 149 | +web-based tool is provided only for convenience and quick reference, you |
| 150 | +should refer to the |
| 151 | +<a href="https://code.google.com/p/v8/wiki/V8Profiler"> |
| 152 | + command-line</a> |
| 153 | +version for full output. |
