func EnableOpenCensusTracing ¶ Uses

func EnableOpenCensusTracing()

EnableOpenCensusTracing installs OpenCensus as a tracing backend for LUCI packages.

func Sampler ¶ Uses

func Sampler(spec string) (trace.Sampler, error)

Sampler constructs an object that decides how often to sample traces.

The spec is a string in one of the forms:

* `X%` - to sample approximately X percent of requests.
* `Xqps` - to produce approximately X samples per second.

Returns an error if the spec can't be parsed.
