API: Requests

Event: 'request'

  • 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).
