-Package trace contains support for OpenCensus distributed tracing.
-
-The following assumes a basic familiarity with OpenCensus concepts.
-See http://opencensus.io
-
-
-Exporting Traces
-
-To export collected tracing data, register at least one exporter. You can use
-one of the provided exporters or write your own.
-
- trace.RegisterExporter(exporter)
-
-By default, traces will be sampled relatively rarely. To change the sampling
-frequency for your entire program, call ApplyConfig. Use a ProbabilitySampler
-to sample a subset of traces, or use AlwaysSample to collect a trace on every run:
-
- trace.ApplyConfig(trace.Config{DefaultSampler: trace.AlwaysSample()})
-
-
-Adding Spans to a Trace
-
-A trace consists of a tree of spans. In Go, the current span is carried in a
-context.Context.
-
-It is common to want to capture all the activity of a function call in a span. For
-this to work, the function must take a context.Context as a parameter. Add these two
-lines to the top of the function:
-
- ctx, span := trace.StartSpan(ctx, "example.com/Run")
- defer span.End()
-
-StartSpan will create a new top-level span if the context
-doesn't contain another span, otherwise it will create a child span.
