Module oc_sampler_probability

This sampler assumes the lower 64 bits of the trace id are randomly distributed around the whole (long) range.

Behaviours: oc_sampler.

Description

The sampler creates an upper bound id based on the configured probability and compares the lower 64 bits of the trace id to for the sampling decision.
