Jaeger Sampling Configuration Is Not Working Correctly (Doc ID 2868584.1)

Last updated on SEPTEMBER 29, 2023

Applies to:

Goal

1. When changing the JAEGER_SAMPLER_TYPE to probabilistic and keeping JAEGER_SAMPLER_PARAM to 0.1, its not capturing any traces in the Jaeger whereas as per the documentation, it should capture 1 trace out of 10.

2. When changing the JAEGER_SAMPLER_TYPE to const and keeping JAEGER_SAMPLER_PARAM to 1, It should capture all the traffic in the Jaeger. But it is not working as per design. I sent almost 242 message but it captured only 184 messages/traces. I simulate this test case with different traffic message count but everytime, it was capturing few traces only. I have attached snapshot for your reference.

3. When changing the JAEGER_SAMPLER_TYPE to ratelimiting and keeping JAEGER_SAMPLER_PARAM to 1, so as per the Jaeger documentation, it should capture 1 traces per second. I generated almost 40 packets ( 20 initial + 20 termination ) per second and kept shooting the traffic for 10 second, Ideally it should capture only 10 packets but it captured 153 traces. For your reference, snapshot attached.
