ErrConfiguration is the base exception for tracing configuration errors.
Functions ¶
func IsSampled ¶ added in v1.18.0
func IsSampled(span opentracing.Span) bool
IsSampled returns the sampling status (true/false) of a span. Most implementations support checking this status. Unfortunately, we hide the tracing implementations behind unified opentracing interfaces. The single input is an opentracing.Span interface. As a result, we need to type-cast it back to all supported implementations. This status is particularly useful when a span is not free to collect, or has to turn on some special configs. One example is Git Trace2. It's a built-in observability tool that provides a deeper look into Git processes. Enabling this feature is not expensive, but not cheap either. We don't want to enable it for all Git processes. So, it makes sense to collect such data when the parent span is sampled.
