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> \
java -Dloader.path='aws.jar,aws.jar!/lib' -Dspring.profiles.active=aws \
-cp zipkin.jar org.springframework.boot.loader.PropertiesLauncher

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 ?

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

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

Hi!

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!

Kr

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

Hey all,
I am using zipkin to trace my http calls ( express nodejs ) and struggling to trace the database requests ( mongoose and sequelize ). Is there any solution available for databases in zipkin-js ??

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.

What should one annotate on span? Whats the difference between tags and annotate? Any link to documentation to help me understand? Thanks!
