Hello, again. I got the following errors when I tried to build a local docker image (on an amd64 machine):

$ git clone https://github.com/openzipkin/zipkin.git
$ cd zipkin

Any ideas to solve this? There should be some prerequisites before running the command?

Hi, there, could someone advice - when I'm running npm -v in Windows I'm getting the following error: 'CALL "C:\Program Files\nodejs\node.exe" "C:\Program Files\nodejs\node_modules\npm\bin\npm-cli.js" prefix -g' is not recognized as an internal or external command,
operable program or batch file.

I tried to configure zipkin to connect to mysql: java -jar zipking..jar STORAGE_TYPE=mysql MYSQL_JDBC_URL=jsbc:mysql://mysql-server:3306/zipkin .... but i do not see any table created in the database zipkin I checked db connection is fine

lukemao

@lukemao

We found the fix. STORAGE_TYPE etc should be set as a env variable not a java -jar param

hi, I have springboot application which was migrated from older spring web, so application-context.xml is still there

after adding dependencies and relevant properties, even though I can see spanId / traceId in logs, I dont see anything in zipkin. SHould I configure reporter beans manually ?

Normal spring boot applications are working fine except this migrated legacy application

any suggestions ?

This does not seem to be a Zipkin question, you can ask SLeuth-related questions here: https://gitter.im/spring-cloud/spring-cloud-sleuth
If you want to send data to ZIpkin you need to add spring-cloud-sleuth-zipkin, check the docs for a full example: https://docs.spring.io/spring-cloud-sleuth/docs/current/reference/htmlsingle/#how-to-set-up-sleuth-with-brave-zipkin-http

Hello community I am having issues accessing the UI for a deployed zipkin on kubernetes through an ingress. For some reason, whenever I try to access the UI (from the path examplehostname/zipkin) I am receiving redirect errors (ERR_TO_MANY_REDIRECTS shown by browser). However, all of the other endpoints appear to be working fine and return the correct information when I curl them (examplehostname/zipkin/info, examplehostname/zipkin/health, etc...) and I have applications which can successfully send tracing data to examplehostname/zipkin/api/v2/spans. The UI is just inaccessible, was wondering if anyone can help?

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"
       }
     }
   }
 }
}

Andriy Redko

@reta

@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

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, 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?
