i know this is a very general question but i simply don't know how to start.
I have spring-boot applications which serve a thrift API via HTTP.
The same or another spring-boot app is using the thrift-client of another application to communicate.
my goal is to trace the communication path with zipkin.
i could imagine, i need to somehow intercept incoming and outcoming http-calls with the application-type x-thrift but simply have no idea how to do this and properly integrate with zipkin libraries.
any hint how to start on this is highly appreciated, thanks a lot in advance
i think i found a suitable way to do this. After further thinking my idea went into the direction of using annotations and aspects for intercepting HTTP requests from/to thrifts http client which seems to be quite some work.
after further search, i found this library for spring-boot serving exactly my needs:

Using google i found two possible solution for now:
-using spring boot with kotlin
-using this kotlin client https://github.com/jillesvangurp/kt-search
I've already finished the android client application in kotlin but now i have to find a way to make this client comunicate with elasticsearch.
What would it be the best solution for my problem that i could look up online
Thanks in advance
First, if you don't use Spring in the current application, integrating it (if possible) would be a lot of work and most likely not worth it.
Another alternative would be to use the officially supported Java client for Elasticsearch (https://www.elastic.co/guide/en/elasticsearch/client/java-api-client/current/index.html).
BUT, you should keep in mind that, if you put the Elasticsearch client in your client application, that the credentials, you may use, will also be in the client application.
They could be accessible for everyone using the Android client and the user could perform any request on the Elasticsearch. Also you couldn't change them without updating the client.
So, it is likely better to use a Three-Tier-Architecture (https://www.ibm.com/topics/three-tier-architecture) and creating an API service to handle the Elasticsearch requests.
I wrote some micro-services using Quarkus that communicate via Artemis. Now I want to add OpenTelemetry for tracing purpose.
What I already tried is to call service B from service A using HTTP/REST. Here the trace id from service A is automatically added to the header of the HTTP request and used in service B. So this works fine. In Jaeger I can see the correlation.
But how can this be achieved using Artemis as messaging system? Do I have to (manually) add the trace id from service A into the message and read it in service B to setup somehow the context (don't know whether this is possible)? Or is there possibly an automatism like for HTTP requests?
I would appreciate any assistance.
I have to mention at this point that I have little experience with tracing so far.
There is no quarkus, quarkiverse extension or smallrye lib that provides integration with Artemis and OpenTelemetry, yet.
Also, OpenTelemetry massaging spec is being worked at the moment, because the correct way to correlate sent, received messages and services is under definition at the OTel spec level.
However, I had exactly the same problem as you and did a manual instrumentation that you can use as inspiration: quarkus-observability-demo-activemq
It will correlate the sent service as parent of receiving end.
I implementing Distributed tracing in microservices. I'm using feign client for inter service communication and using micrometer for tracing. But I'm getting different trace id when I call Service B from Service A using feign Client. I read a lot of articles regarding this issue, but didn't find any solution. Could anyone please help me in this? I'm using spring boot 3.0.0-Snapshot.
I expect someone will help me in this problem so I can move forward with my work, I'm stuck due to this issue.
ahc and ahc-ws (Async Http Client) components have been deprecated in Apache camel version 3.16: https://issues.apache.org/jira/browse/CAMEL-17667.
Is there an alternative for ahc-ws? The component was very easy to use to consume external websockets API.
Other libraries like Jetty, Undertow, Atmosphere, don't seem to offer this kind of features. I have not been able to configure them and the documentation remains unclear. They only provide the server part.
For the websocket-jsr356 component, I can't configure the component to consume a WebSockets over SSL API (wss). The library seems to support only classic websocket (ws).
I looked for alternatives on the camel doc, examples on github but I didn't find anything.
Is there a viable alternative to ahc-ws to consume external websocket APIs simply with camel?
Thanks a lot
Looks like it's not deprecated yet. There is just a suggestion for that. ahc-wss is very useful currently and there is no viable alternative for the same. websocket component requires tedious tweaking of secure storage parameters and is just kills the purpose of wss. I hope they don't deprecate ahc-wss without a proper replacement though.
We are thinking about having a micro service architecture in our business application. We think about having the communication via ampq. With this researches that i made for that, the question comes up: How to standardise the communication while programming?
For example: If you do some database requests you can use spring-data-jpa that creates for you the code to send those requests.
Isn't there a way to use something like that for AMQP requests if you need an object from another service, something like an AMQPRepositories to have this standardised way?
Does someone has some other ideas or made some experiences with that?
