Functions

func Metrics

func Metrics(rds *srvhttp.RequestDurationSeconds, addPath bool) gin.HandlerFunc

Metrics is a gin middleware that adds request histogram. Setting addPath to true will make histogram to use request path as a dimension. This is ok with few total number of paths, but incurs performance issue if the cardinality of request path is high.

func Trace

func Trace(tracer stdtracing.Tracer, keyer contract.Keyer) gin.HandlerFunc

Trace is a gin middleware that adds opentracing support.
