From: Marcin Grzejszczak Action0 instances into their Sleuth representative -
the TraceAction. The hook either starts or continues a span depending on the fact whether tracing was already going
on before the Action was scheduled. To disable the custom RxJavaSchedulersHook set the spring.sleuth.rxjava.schedulers.hook.enabled to false.
You can define a list of regular expressions for thread names, for which you don’t want a Span to be created. Just provide a comma separated list
+of regular expressions in the spring.sleuth.rxjava.schedulers.ignoredthreads property.
spring.sleuth.zuul.enabled property
