 - For `traceidratio` and `parentbased_traceidratio` samplers: Sampling probability, a number in the [0..1] range, e.g. "0.25". Default is 1.0 if unset.
 - For `jaeger_remote`: The value is a comma separated list:
-  - `endpoint`: the endpoint in form of `host:port` of gRPC server that serves the sampling strategy for the service ([sampling.proto](https://github.com/jaegertracing/jaeger-idl/blob/master/proto/api_v2/sampling.proto)).

   - `pollingIntervalMs`:  in milliseconds indicating how often the sampler will poll the backend for updates to sampling strategy.
   - `initialSamplingRate`:  in the [0..1] range, which is used as the sampling probability when the backend cannot be reached to retrieve a sampling strategy. This value stops having an effect once a sampling strategy is retrieved successfully, as the remote strategy will be used until a new update is retrieved.
