Hey everyone, I want to use the kafka collector but my cluster is setup with SASL_SSL with GSSAPI sasl mechanism. The collector is having trouble connecting to the cluster. I also want to use kafka as storage so I will probably need to add similar configs for that as well. Can you please provide some help. I tried running the zipkin jar like this. I removed some of the sensitive information.

KAFKA_BOOTSTRAP_SERVERS=SASL_SSL://ip:port,SASL_SSL://ip:port java -Dzipkin.collector.kafka.overrides.sasl.mechanism=GSSAPI -Dzipkin.collector.kafka.overrides.security.protocol=SASL_SSL -Djava.security.auth.login.config=/path/jaas.conf -Djava.security.krb5.conf=/path/krb.conf -Djavax.security.auth.useSubjectCredsOnly=true -Dzipkin.collector.kafka.overrides.ssl.truststore.location=/path/truststore.jks -Dzipkin.collector.kafka.overrides.ssl.keystore.location=/path/keystore.jks -Dzipkin.collector.kafka.overrides.ssl.truststore.password=pass -Dzipkin.collector.kafka.overrides.ssl.keystore.password=pass -Dzipkin.collector.kafka.overrides.ssl.key.password=pass -Dzipkin.collector.kafka.overrides.sasl.kerberos.service.name=name -jar zipkin.jar --logging.level.zipkin2=DEBUG

The zipkin server starts with no errors but doesn't seem like the collector is connected to the cluster. Am I using the right properties?

I also tried using the docker zipkin image. These are the env I set when creating the container. It's pretty much the same as above.

KAFKA_BOOTSTRAP_SERVERS=SASL_SSL://ip:port,SASL_SSL://ip:port JAVA_OPTS=-Dzipkin.collector.kafka.overrides.sasl.mechanism=GSSAPI -Dzipkin.collector.kafka.overrides.security.protocol=SASL_SSL -Djava.security.auth.login.config=/path/jaas.conf -Djava.security.krb5.conf=/path/krb.conf -Djavax.security.auth.useSubjectCredsOnly=true -Dzipkin.collector.kafka.overrides.ssl.truststore.location=/path/truststore.jks -Dzipkin.collector.kafka.overrides.ssl.keystore.location=/path/keystore.jks -Dzipkin.collector.kafka.overrides.ssl.truststore.password=pass -Dzipkin.collector.kafka.overrides.ssl.keystore.password=pass -Dzipkin.collector.kafka.overrides.ssl.key.password=pass -Dzipkin.collector.kafka.overrides.sasl.kerberos.service.name=name

When the zipkin container starts up, I get this class not found error. Is the java inside the container missing that class? How can I add it?

Hi Zipkin - I am working on a group project for a data visualization course via UC Berkeley. We've decided to see if we can create some new, useful visualizations of trace data, both at the single trace level, and at the aggregate level (i.e. visualizations for groups of traces). Have two questions for the community: 1) are there good public datasets that we could use as we develop the viz? some sets of zipkin traces in JSON or other accessible format? 2) is there an existing list of visualizations that have been proposed for zipkin, but nobody's gotten around to implementing them?

Hello team, I need some clarification on remoteEndpoint. Zipkin's documentation says it's an RPC (or messaging) span, indicating the other side of the connection, but I'm not sure of what this means. There is an ipv4 field under remoteEndpoint. Can it be an IP address of an external user?

hello guys, another thing ... I was able to manage to run the zipkin and was able to store traces successfully in Cassandra.. but now it doesn't show any dependencies .. traces are all good, accurate and "realtime" but when I click on dependencies it's empty.. .I read I have to set the zipkin-dependencies.jar to be run periodically so I did (based on this article https://stackoverflow.com/questions/37459261/cant-view-any-dependencies-inside-zipkin-ui-dependencies-tab ) but hell - it doesn't show anything still.. I even tried to run that as a service .. but no luck either ...

hello guys, I have a question .... I have finally managed to make Zipkin + Cassandra work together... however, to properly display dependencies I need to periodically run zipkin-dependencies.jar (as mentioned above) ... I do this via cron in linux ... the problem is -> it takes a little over 1hr to calc the data...

Is there any way to limit the spans to automatically check for those nonprocessed only? or any other way I can tune cassandra / zipkin-dependencies.jar to make it work faster? Any tips?

I am not sure if I should focus on the cassandra tuning or the problem is somewhere else ... I tried to run twice manually the zipkin-dependencies and it says:
Running Dependencies job for 2021-03-01: 1614556800000000 =< Span.timestamp 1614643199999999 for both instances ... so it obivously recalc the same data ...

Hi,

I'm running zipkin in a container and sending a get (wrapFetch/node-fetch) trace to it (zipkin-transport-http):

const { Tracer } = require('zipkin');
const { BatchRecorder } = require('zipkin'); // format data spans
const { HttpLogger } = require('zipkin-transport-http');
const fetch = require('node-fetch');

const wrapFetch = require('zipkin-instrumentation-fetch');
const CLSContext = require('zipkin-context-cls'); // continous local storage
const ctxImpl = new CLSContext();

const localServiceName = 'xxx';

const recorder = new BatchRecorder({
logger: new HttpLogger({
endpoint: http://localhost:9411/api/v1/spans
})
});

const tracer = new Tracer({ ctxImpl, recorder, localServiceName });

const remoteServiceName = 'youtube';
const zipkinFetch = wrapFetch(fetch, { tracer, remoteServiceName });

zipkinFetch('https://www.youtube.com/').then(res => res)

How do I go about instrumenting and sending my own span?

Thanks,

Is it the right practice for applications to wait for the Zipkin collector to be available? Can the application proceed further to serve its users and send no trace info as a collector is unavailable? Maybe the application can somehow automatically sense the collector and reload it-self. Am I thinking correct?

Hi everyone. My kafka cluster is using SASL_SSL GSSAPI. I have a kafka connect that is able to connect to authenticated cluster and produce and consume data from it. The issue is when I add the brave-kafka-interceptor and use the kafka collector, the connect is unable to produce data to cluster. The brave-kafka-interceptor is setup correctly because it works fine when using HTTP collector. I believe the interceptor also requires the SASL_SSL GSSAPI, truststore, keystore, jaas, krb configs when using with KAFKA collector. Does anyone know how I can set them? I already setup zipkin with the authentication configs and it seems to be connected to the cluster.

^ first time trying this thing out, presumably I'm missing something. My app talks to a db and a 3rd party service.
Seems like none of the folding or annotation stuff is available? I'm trying opentelemetry from node, there doesn't seem to be a way to override the serviceName for the http or the db? The remoteService? Is there some way to tag spans so they are remote? Change their kind? Really don't know where to look.

This may be answered somewhere else, but why does the Brave library expect headers to be in a case sensitive format when extracting them with an Extractor? For example it won't detect "x-b3-traceid" but will "X-B3-Traceid". I'm fairly certain the RFC for headers declares headers as case-insensitive

Hi all, running into a small issue connecting Zipkin to AWS Elasticsearch. Initially I was getting EmptyEndpointGroupException then I forced the health check off and realized that Zipkin couldn't find the AWS credentials so it's throwing "User: anonymous is not authorized to perform: es:ESHttpGet". This is what I'm using to execute:
STORAGE_TYPE=elasticsearch \
ES_HOSTS=https://<domain>.us-east-1.es.amazonaws.com/ \
ES_HEALTH_CHECK_ENABLED=false \
java -Dloader.path='aws.jar,aws.jar!/lib' -Dspring.profiles.active=aws \
-cp zipkin.jar org.springframework.boot.loader.PropertiesLauncher

I've even tried to forcing the environment variables but still same issue:
STORAGE_TYPE=elasticsearch \
ES_HOSTS=https://<domain>.us-east-1.es.amazonaws.com/ \
ES_HEALTH_CHECK_ENABLED=false \
AWS_ACCESS_KEY=<access> \
AWS_SECRET_KEY=<secret> \

OK probably religious issue here.... which is the recommended one Cassandra or Elasticsearch for the Storage option? After mucking around with ES, it seems that unless it's managed by AWS or you dedicate a whole computer to it. ES is genreally a pain in the arse to work with. Mind you I think Cassandra looks to be a big beast to deal with as well.

This is interesting as it is an error while serializing a Span for the Zipkin client. Upon closer inspection, there is a Tag map in the spans that seems a candidate for the concurrency issue. If the Span is being serialized and a new Tag or something is being added to it concurrently, we may run into an issue.

Does any of you have seen this issue or are aware of it? Any help would be appreciated.

Regards.

Hello!

I wanted to open a possible bug issue but came to ask here first.

I am using Spring Boot, Sleuth and Brave. There is a weird race condition that pops up and we are stumped.

The issue investigation is described here spring-cloud/spring-cloud-sleuth#1814 where Brave throws an exception "Parent can only be null in a local root". In the last message (https://github.com/spring-cloud/spring-cloud-sleuth/issues/1814#issuecomment-767389228) is the "stumped" part. In debug another subsequent call to the same method works fine.

Any help would be much appreciated.

Is it possible to use custom id as a trace id in zipkin ?

https://stackoverflow.com/q/66777772/2715083

We have around 10 Spring boot microservices, which communicate with each other via kafka. At the start of any flow, a message-id is generated by one of our microservices, and that is propagated to all the others as part of the message transfer. We search for this message-id in our kibana logs to find the error.
So I wanted to understand if Zipkin can work with the message-id that our ecosystem already produces, instead of generating a new one ?

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! We've upgraded to Finagle 21.2.0 and Scala 2.13 and now Finagle can't find HttpZipkinTracer even though it's definitely on the classpath. Any ideas why is this happenning? Thank you!
