hello guys, I just have a question ... I have zipkin running together with cassandra as its persistent storage .. the issue I have is that with the external storage I have to recalc dependencies periodically .. it takes a bit over an hour to get that done ....

Is there the same issue with ElasticSearch ??? or is it faster? or do you have any tips how to speed it up??

Hi there, I’m from StreamNative, now working at organizing the Pulsar Virtual Summit NA 2021. I’m trying to get in touch with our Zipkin community and invite as one community partner of Pulsar Summit NA 2021. In the past events, we have lots of successful experiences with different communities. Also, welcome community members to submit talks on Apache Pulsar + Zipkin(https://sessionize.com/pulsar-summit-north-america-2021).
I’m not sure this is the right place to talk about this. So, Looking forward to your reply. Thanks a lot!

Hey, i have question regarding the OpenZipkin-Java (Brave) Tracing.currentTracer().currentSpan() usage. It returns lazy span. However when we try to finish that span using currentSpan().finish() it does not report the duration. Is this inteded ? I thought use the trace context in same thread different methods with currentSpan should work.

Hi all,I have deployed Jaeger on istio to monitor the bookinfo application. Then I want to analyze the trace data of Jaeger. However, I am confused by some span tags, such as, upstream_cluster and peer address. I found the meaning of peer.address from https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/sdk_exporters/zipkin.md
, It says that peer.address means remote address. I think it means that when a client start a request and a server receive the request, the client's peer.address will be the server and the server's peer address will be the client.

Here is some information I get from one trace with 8 spans.

             spanID                                      operationName          podIP           serviceName               pid   refType   peer.address span.kind
0  0044bea01e572833  productpage.default.svc.cluster.local:9080/pro...  istio-ingressgateway                         client

4  9c1aaf91ea5e5ce9           reviews.default.svc.cluster.local:9080/*   productpage.default  a2bdd3593ab25d00  CHILD_OF    client
5  923db83990a9e7e5           reviews.default.svc.cluster.local:9080/*       reviews.default  9c1aaf91ea5e5ce9  CHILD_OF    server
6  8e3dbd4dd0b70f85           ratings.default.svc.cluster.local:9080/*       reviews.default  923db83990a9e7e5  CHILD_OF    client

However, the peer.address seems to be it's parent span's pod id, which is different from what I understand, and I don't know which is right.

Besides, I don't understand the meaning of upstream_cluster and downstream_cluster as below. Why all downstream_cluster is None, and what is the meaning of '9080' and 'inbound' in outstream_cluster?

             spanID                                      operationName          podIP  ...                                   upstream_cluster downstream_cluster span.kind

At our company we're going to implement Zipkin. However as database we're obliged to use PostgreSQL. Is there any documentation regarding the database component so that we could write our own implementation?

I checked out the Zipkin source code/javadoc and also looked at the Cassandra and ElasticSearch implementations but some kind of documentation would be very helpful.

Maybe other remarks that we should take into account? Or tips to make this implementation easier?

Thanks in advance for the info!

I have questions on zipkin-dependencies.
  1. I am running dockerized zipkin with mysql as storage. It also runs zipkin-dependencies looking at docker-compose file. To run MySQL, was it necessary to run zipkin-dependencies?
  2. How can I manually call zipkin-dependencies for aggregration purpose while running as a dependency in 1. Or does it runs automatically when a data is sent to zipkin? Or does run as stated end of the day?

Hi! I'm relatively new to Zipkin, and I wanted to create a simple protobuf example. I had trouble modifying https://github.com/openzipkin/brave-example to upload spans in the protobuf format.
Golang seemed more protobuf encoder friendly, so I created a small example application along the lines of "brave-example", "zipkin-php-example", & "zipkin-js-example". If anyone is interested or has feedback, the repo is here: https://github.com/smlobo/zipkin-go-example

I was typing up a question here about how I could include Zipkin as part of my Spring Boot project as a subproject (Gradle) without using EnableZipkinServer, Docker Compose or the self-contained jar since the compose setup has problems with live-reload and cache sharing, while the self contained jar would've been available with Gradle ideally to avoid unnecessary binaries in the repo. I soon answered my own question after thinking it through, so I wanna document it for archival's sake even if it may be almost obvious to someone more experienced:

Treat Zipkin as an external service, and use Docker Compose to describe your external services. This also includes things like databases, messaging servers and cache servers. Use Docker Compose to ready the infrastructure and let your build tool manage your code outside Docker instead. No custom binaries for your external dependencies, no manual cache management, and as an added bonus, single command infrastructure.

I sure would've loved to grok this earlier so I didn't have to spend so many days trying different options. Ah well, sometimes you learn the hard way xD

Hi! I tried zipkin today and provided several microservices with tracing. It basically works, ziupkin displays spans from each microservice, but they are completely distinct. Zipkin does not make a connection between services. I'm sure i am missing any configuration on how zipkin is able to connect the services.

Hi everybody, just joined!
I have a question, let's say I have an API and I want to trace all the incomming request and all the internal functions that the API processes, for example I recive a request to an endpoint '/do_foo/' and it calls he function 'do_bar', I would like to have a span in there and I do not manage to make it even using the python decorator @zipkin_span with the same service_name in the function 'do_bar', is it even possible to track internal calls inside a zipkin trace?

Hello everybody, just joined. I was trying to use Zipkin for a few days in my Ruby on Rails app and I am using::Logger::Formatter.new as the formatter. How do I print the trace id, span id etc in the application logs ?

In my Java App it automatically comes as "[vmsservice,c6b162b6763740b6,93228fedf49d17c2,true]" as part of the log.

Hi, I'm using Zipkin with Elasticsearch. My Problem is that the Zipkin UI doesn't display all traces. I've generated 1000 traces but only 782 of them are visible. Furthermore, the number of spans for the traces in the UI is incorrect. But if I click on the 'show' button for one trace, the trace is displayed with the correct number of spans. I also checked the /trace endpoint. It's possible to fetch a single trace, but if I want to fetch all 1000 traces, I only get the 782 traces with an incorrect number of spans. Does anyone have an idea how to fix this?
