HTTP Tracing

In Go 1.7 the HTTP tracing package was introduced to facilitate the gathering of fine-grained information throughout the lifecycle of an HTTP client request. Support for HTTP tracing is provided by the net/http/httptrace package. The collected information can be used for debugging latency issues, service monitoring, writing adaptive systems, and more.

Notes

The httptrace package provides a number of hooks to gather information during an HTTP round trip about a variety of events. These events include:

• Connection creation
• Connection reuse
• DNS lookups
• Writing the request to the wire
• Reading the response
