Requests Module

The SDK should auto-instrument all outgoing HTTP requests, regardless of the library that issues the requests. Each outgoing request should result in a span.

Span Conventions

Span Attributes

Span Data

Refer to HTTP Span Data Conventions for a full list of the span data attributes. Note these caveats:

• the server.address span data attribute is only required if the URL is relative

Instrumentation

The SDK should create a span when the HTTP request is complete, and attach all the relevant available data.

Example

Consider the website example.com. This code, running on the page:

fetch("/data.json")

Should result in the following span, assuming the request was successful:

{
  "description": "GET /data.json?user=1",
  "op": "http.client",
  "data": {
    "http.query": "user=1",
    "http.request_method": "GET",
    "http.response.status_code": 200,
    "http.fragment": "",
    "server.address": "example.com"
    ... other span properties
  }
}

NOTE: Refer to HTTP Span Data Conventions for a full list of properties you can attach to an http.client span.
