Variables

var WithAnalytics = tracing.WithAnalytics

WithAnalytics enables Trace Analytics for all started spans.

var WithAnalyticsRate = tracing.WithAnalyticsRate

WithAnalyticsRate sets the sampling rate for Trace Analytics events correlated to started spans.

var WithHeaderTags = tracing.WithHeaderTags

WithHeaderTags enables the integration to attach HTTP request headers as span tags. Warning: Using this feature can risk exposing sensitive data such as authorization tokens to Datadog. Special headers can not be sub-selected. E.g., an entire Cookie header would be transmitted, without the ability to choose specific Cookies.

WithServiceName sets the given service name for the returned router.

var WithSpanOptions = tracing.WithSpanOptions

WithSpanOptions applies the given set of options to the span started by the router.
