Tracing

Wrappers

Instana provides native wrappers for the following GoLang packages:

OpenTracing

Manual tracing in Go works based on the OpenTracing API, and the data those produce get "translated" into Instana through a tracer and sent to the Instana backend. See refer to the Instana GoLang OpenTracing documentation for details.

AutoProfile™

Note: This feature is currently in beta-testing.

AutoProfile™ generates and reports process profiles to Instana automatically and continuously. Learn more about profiles in Analyze Profiles section.

To enable AutoProfile™ add EnableAutoProfile: true option in instana.InitSensor(opt). For detailed instructions, see github.com/instana/go-sensor.

If you need to enable profiling for an app without code changes, set INSTANA_AUTO_PROFILE=true env variable. Note that this value takes precedence and overrides any attempt to disable profiling from inside the application code.

Mode

  • Cross host and cross language tracing
