Amazon.XRay.Recorder.Core.Sampling Namespace

Making sampling decisions based on sampling rules defined by X-Ray control plane APIs.It will fall back to LocalizedSamplingStrategy if sampling rules are not available.

Class for keep list of sampling rules from x-ray backend.

Class for keep last rule modification timestamp and list of sampling targets from x-ray backend.

Thread safe reservior which holds fixed sampling quota, borrowed count and TTL.

Cache sampling rules and quota retrieved by RulePoller and TargetPoller. It will not return anything if the cache expires.

Gets sampling rules from X-Ray service. This is a asynchronous operation.

Sampling input for "ShoudTrace" method.

Sampling result returned by ShoudTrace().

It represents the Rules used for sampling.

Connector class that translates Sampling poller functions to actual X-Ray back-end APIs and communicates with X-Ray daemon as the signing proxy.

This class records requests matched, borrowed and sampled count for the given rule.

Stores records received from GetSamplingTargets API call.

The poller to report the current statistics of all sampling rules and retrieve the new allocated sampling quota and TTL from X-Ray service.

Stores timestamp for the operations in unix seconds.

Class for xray configuration for getting sampling rules and sampling targets.

Interface of sampling strategy which is used to determine if tracing will be enabled for a given request.

An Enum of decisions, the reservoir could make based on assigned quota with TTL and the current timestamp/usage.
