Tielem opened a new issue #3727: Support for Distributed Tracing with OpenTracing URL: https://github.com/apache/pulsar/issues/3727 ### Is your feature request related to a problem? Please describe. Distributed tracing, also called distributed request tracing, is a method used to profile and monitor applications, especially those built using a microservices architecture. Distributed tracing helps pinpoint where failures occur and what causes poor performance. *From the description of OpenTracing* - https://opentracing.io/docs/overview/what-is-tracing/ ### Describe the solution you'd like The topic was raised on Slack a couple days ago, involving @merlimat. @merlimat mentioned at one point that there were talks of integrating OpenTracing in Pulsar (and I assume Bookkeeper, Zookeeper, Presto, ... by extension). OpenTracing can be used by multiple visualization tools, such as Jaeger. If added to the deployment scripts, maybe Jaeger (https://www.jaegertracing.io/) could be integrated as well (similar to Prometheus and Grafana). ### Describe alternatives you've considered None, but open to alternatives. OpenTracing is fairly industry standard though. ### Additional context I'd be interested in feature testing this, however our Pulsar deployment is not yet mature enough to do so at this point in time. We also don't (yet) cover any use cases involving Presto or Pulsar Functions. Ideally, some other people raise interest in this feature and are willing to help feature test this.
