Hi All can somebody hint me on how to manage span creation in micro-services with reactive nature when we don't have opportunity to control all the threads...Or if there any way you can aggregate all the spans ?

Hey, anybody tried running Zipkin with OpenSearch (AWS' Elasticsearch "fork"). There seems to be an issue with the version number:

{
 "status" : "DOWN",
 "zipkin" : {
   "status" : "DOWN",
   "details" : {
     "ElasticsearchStorage{initialEndpoints=https://xyz.es.amazonaws.com, index=zipkin}" : {
       "status" : "DOWN",
       "details" : {
         "error" : "java.lang.IllegalArgumentException: Elasticsearch versions 5-7.x are supported, was: 1.0"
       }
     }
   }
 }
}

@Le1632 you should use the property in opensearch.yml: compatibility.override_main_response_version

Hi, I am using Zipkin with cassandra as the backend. Everything has been working fine for months, but now we have started seeing this error frequently in logs

java.util.concurrent.CompletionException: com.datastax.oss.driver.api.core.NoNodeAvailableException: No node was available to execute the query

Did anyone encounter this? If yes, what could be the possible reason

One possible reason of it happening is increase in load. But this error should settle when the load decrease during non peak hours. On the other hand, it's a continuous error and impacting our ingestion into cassandra

Hi, I am unable to see all the trace in zipkin. I am using spring-boot-dependencies 2.2.5.RELEASE. I tried with setting sampler.probability and sampler.percentage to 1.0 and also tried with adding the AlwaysSampler() bean. all did not work. Anyone know why?

Hello people !

We're going to use zipkin, and we're wondering which backend to choose between cassandra and elasticsearch. I couldn't find much information detailed for zipkin's usage, are there some guidelines somewhere to help us with this choice ? pros and cons, performances or whatever
cheers !

Hello, I am sorry to keep asking for a review for my PR (openzipkin/zipkin#3384), but I haven't been able to get my PR to the next step (or make any meaningful progress) for a month. (I only got only one LGTM sign from the reviewers. Thanks, Tommy Ludwig.) Could someone help me?

@gabrielfairbanks

Hello, apologies if it's a stupid question, but we've instrumented a chain of services such as A -> POST -> B -> POST -> C. My tracing json contains details for this chained call, but on the Zipking UI I can only see the calls from A -> B.

Would be correct to expect that call B -> C should be shown on the same zipkin screen, as a child node of service A?

Hey, is it possible to use the ui to search for spans by trace id?

Jonatan Ivanov

@jonatan-ivanov

There is a dedicated input field for that in the top right corner.

Or you can put your traceid into your url :)
/zipkin/traces/{traceId}

The container does not start, it stays in "starting" mode in portainer, then it stops. are the env-var ES_HOSTS and ES_INDEX supported by default in the image?

Hello all. In my tests (v2.23.15), using the ES_INDEX_SHARDS env only takes effect when using ES_INDEX along with it. Only ES_INDEX_SHARDS does not change the number of shards. Is it meant to be like this?

I'm trying to use zipkin zipkin-cassandra with podman-compose on CentOS 8. The docker-compose-dependencies.yml wants to setup a cron job, but maybe it assumes we've somehow got cron in our container already. Is there an easy way to "fix" this podman-compose wise? Error we get: podman start -a dependencies
Error: unable to start container 8ba0b42f90cb60d00b74fe9d85018b9da16a79fcb3f6bba08b480aaa55ffae20: container_linux.go:380: starting container process caused: exec: "crond -f": executable file not found in $PATH: OCI runtime attempted to invoke a command that was not found

Answering my own question: For podman-compose, it's handling of entrypoint was lacking in CentOS 8 (though maybe fixed in a future version). For now I changed the entrypoint in docker-compose-dependencies.yml to: entrypoint: [ 'crond', '-f' ]

Using zipkin cassandra docker-compose with the Centos 8 podman fix, the batch "dependencies", while present and running, doesn't seem to actually do anything. Hints on troubleshooting this?

Hi, I'm trying to setup zipkin with TLS. I'm running it as a docker-compose service with the following env var:

- JAVA_OPTS=-Darmeria.ssl.key-store=/zipkin/keystore.p12 -Darmeria.ssl.key-store-password=password -Darmeria.ssl.enabled=true -Darmeria.ports[0].port=9411 -Darmeria.ports[0].protocols[0]=https

The server starts up and the UI works with https, but zipkin logs Caused by: javax.net.ssl.SSLHandshakeException: error:1000009c:SSL routines:OPENSSL_internal:HTTP_REQUEST every 5 seconds. Any ideas what I'm doing wrong?
