v2.16.2

2.16.2

New Relic's Go agent v3.0 is currently available for review and beta testing. Your use of this pre-release is at your own risk. New Relic disclaims all warranties, express or implied, regarding the beta release.

If you do not manually take steps to use the new v3 folder, as described below, you will not see any changes in your agent.

This is the second release of the pre-release of Go agent v3.0. It includes changes due to user feedback during the pre-release. The existing agent in "github.com/newrelic/go-agent" is unchanged. The Go agent v3.0 code in the v3 folder has the following changes:

• Transaction names created by WrapHandle,
  WrapHandleFunc,
  nrecho-v3,
  nrecho-v4,
  nrgorilla, and
  nrgin now
  include the HTTP method. For example, the following code:

  http.HandleFunc(newrelic.WrapHandleFunc(app, "/users", usersHandler))

  now creates a metric called WebTransaction/Go/GET /users instead of
  WebTransaction/Go/users. As a result of this change, you may need to update
  your alerts and dashboards.

• The ConfigFromEnvironment
  config option is now strict. If one of the environment variables, such as
  NEW_RELIC_DISTRIBUTED_TRACING_ENABLED, cannot be parsed, then Config.Error
  will be populated and NewApplication
  will return an error.

• ConfigFromEnvironment
  now processes NEW_RELIC_ATTRIBUTES_EXCLUDE and NEW_RELIC_ATTRIBUTES_INCLUDE.
