if helpful I once wrote an AWS instance metadata api that has no external deps. Someone can copy/paste it if they like https://github.com/Netflix/denominator/blob/master/core/src/main/java/denominator/hook/InstanceMetadataHook.java https://github.com/Netflix/denominator/blob/master/core/src/test/java/denominator/hook/InstanceMetadataHookTest.java On Wed, Apr 11, 2018 at...
in zipkin we solve this by not including url as a default tag. instead http.path on the other hand, it would be surprising to have url not include the full...
in brave we call this "abandon" not sampling. because sampling is trace tier. literally we have a method span.abandon() with a hazard sign make sure you use this with extreme...
provided instrumentation is written to not inspect noop state, you could possibly transition from false to true, but it is a bit dodgy. In any case, one child could inherit...
Instrumentation can control if abandon is present. otherwise they would need a buddy to filter it out later.. since export is different than the tracer api maybe from config pov...
in brave, we have a client sampler which folks can simply set to false to never have (http) client originated traces. This doesn't mean other local roots can't happen. https://github.com/openzipkin/brave/blob/master/instrumentation/http/src/main/java/brave/http/HttpSampler.java#L38...
It is kindof odd that microsoft aren't upset, neither amazon who literally can't support B3. It is also odd that other sites like Instana also haven't complained. We have certainly...
Here is an example code doc we can consider: "In census all apis named withX replace and old value with a new one. For example, tagger.withContext(context2) will replace, not inherit...
historically speaking, it is likely best to get some of the core finaglers in on this as they'll have more stake in how things go. zipkin for example, it actually...
or trace exporter even. I don't think agent would be required. This would work for the few options census has but there are no direct zipkin reporters for.
