For some reason my docker image can't load org.springframework.boot.loader.PropertiesLauncher
So wanted to see if I could run the main class directly
Juliette Lavoie
Or I guess a better question is... how can I load/add spring boot to my docker image so I can run Zipkin?

How do I connect to a secure aws server/for the storage/backend that does not use kinesis?
Trying to use the zipkin-module-storage-elasticsearch-aws-0.21.3-module but that github is gone... unsure if it's supported anymore or not
I've currently setup a container (openzipkin/zipkin-aws) with a secured AWS ES cluster as storage backend. Everything works as intended. Only the dependencies graph is empty currently. As far as I understood zipkin-dependencies should be used for this. There is a Docker Image (openzipkin/zipkin-dependencies/) available that supports ElasticSearch, but it does not seem to support connecting to a secure AWS ES cluster. Is this correct? Is there anything you can recommend to make the dependency graph in Zipkin work in this setup?
Hello everyone

Hey everyone. I'm trying to mark a span as non-erroneous but I cannot find the way to do so. We're calling an API which returns 409 for valid cases. We don't throw any exception when the API returns 409. I'm not sure if there's some logic down the line that just converts HTTP 409s to errors. Any ideas?

Hello team, I'm trying to convert Tags field in Zipkin's SpanModel from map to string. zSpans is defined like this so I'm trying to call zSpans.Tags but my terminal says

zSpans.Tags undefined (type []*model.SpanModel has no field or method Tags)

which I am confused of because there is a Tags field in SpanModel. Is there a better way to refer to Zipkin's Tags field?

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 guys, my zipkin is working pretty much ok .. the only problem I have is the cassandra integration ... I installed cassandra, run it ... but I cannot force zipkin use it's storage

by simply running "root@machineName ~]# STORAGE_TYPE=casandra java -jar /opt/zipkin/zipkin.jar" it fails to start with



Parameter 0 of constructor in zipkin2.server.internal.ZipkinQueryApiV2 required a bean of type 'zipkin2.storage.StorageComponent' that could not be found.


Consider defining a bean of type 'zipkin2.storage.StorageComponent' in your configuration.

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 ...

my zipkin service:
Description=Managa Java service

ExecStart=/usr/bin/java -jar zipkin.jar


my zipkin-dependency.sh (crontab - every 5 mins)
STORAGE_TYPE=cassandra3 /usr/bin/java -jar /opt/zipkin/zipkin-dependencies.jar

crontab -l
*/5 * * * * cd /opt/zipkin && ./zipkin-dependencies.sh

any thoughts?

Does Zipkin work Amazon keyspaces as the cassandra store?
Petr Hybler

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 ...

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?
