Generating Data:
----------------

[](#generating-data)

```
$et = new \EventTracer("myeventlog.json");

$et->begin("Eating Cake");
[...]
$et->end();
```

If filename isn't specified, then data will be buffered in-memory (`$et->buffer`) and can be written to disk in one go with `$et->flush($filename)`.

Viewing Data:
-------------

[](#viewing-data)

Use [Perfetto](https://ui.perfetto.dev) and "Open trace file"

[Google Doc](https://docs.google.com/document/d/1CvAClvFfyA5R-PhYUmn5OOQtYMH4h6I0nSsKchNAySU/edit)
