Features
- Updated
koainstrumentation to properly wrapRouterwhen using@koa/router@15.0.0+ (#3550) (f1e08ad) - Added ability to configure a ratio based sampler (#3501) (f300bd5)
- To assign a ratio based sampler, set
config.distributed_tracing.sampler.root,config.distributed_tracing.sampler.remote_parent_sampled, orconfig.distributed_tracing.sampler.remote_parent_not_sampledto{ trace_id_ratio_based: { ratio: <float between 0 and 1> }} - To assign via environment variables set
NEW_RELIC_DISTRIBUTED_TRACING_SAMPLER_<TYPE>='trace_id_ratio_based'andNEW_RELIC_DISTRIBUTED_TRACING_SAMPLER_<TYPE>_RATIO=<float between 0 and 1>where<TYPE>is one ofROOT,REMOTE_PARENT_SAMPLED, orREMOTE_PARENT_NOT_SAMPLED
- To assign a ratio based sampler, set
- Updated configuration to allow
adaptive.sampling_targetto be set forconfig.distributed_tracing.sampler.root,config.distributed_tracing.sampler.remote_parent_sampled, andconfig.distributed_tracing.sampler.remote_parent_not_sampled(#3532) (44f51dd) - Added support for OTEL span links (#3528) (e840690)

agent.sampler.*(#3527) (ad63441) - Updated
Samplersclass to normalize logger messages, short circuit when applicable and remove optional chaining checks (#3546) (4f7684c) - Updated samplers to assign priority between 0-1 when DT is disabled or both full and partial granularity are disabled (#3559) (7a1c37e)
- Updated transaction to store partial granularity indicator as
.partialType(#3561) (a7f20d8) - Updated when partial granularity rules are applied (#3553) (a4bdf4f)
