API: Requests

Event: 'request'

Requests are a special type of event emitted by appmetrics. All the probes named above can also create request events if requests are enabled. Howver requests are nested within a root incoming request (usually http). Request events are disabled by default.

* `type` (String) The type of the request event. This is the name of the probe that sent the request data, e.g. `http`, `socketio` etc.
* `name` (String) The name of the request event. This is the request task, eg. the url, or the method being used.
* `request` (Object) the detailed data for the root request event:
    * `type` (String) The type of the request event. This is the name of the probe that sent the request data, e.g. `http`, `socketio` etc.
    * `name` (String) The name of the request event. This is the request task, eg. the url, or the method being used.
    * `context` (Object) Additional context data (usually contains the same data as the associated non-request metric event).
    * `stack` (String) An optional stack trace for the event call.
    * `children` (Array) An array of child request events that occurred as part of the overall request event. Child request events may include function trace entries, which will have a `type` of null.
