zipkin-rabbit-test

A test for trying to prove missing zipkin traces for timed-out RabbitMq requests.

Prerequisites

A RabbitMq broker & a Zipkin collector are required. Both can be started via the provided docker-compose.yml file, e.g. by running this in the root of the project:

docker-compose up -d

Execution

This is a maven project, so it can be run with:

mvn clean spring-boot:run

Alternatively, it can be loaded & run from an IDE (e.g. IntelliJ IDEA).

Once the app is running, test with:

curl --location --request POST 'localhost:8080/test/echo' \
--header 'Content-Type: application/json' \
--data-raw '{
    "message": "hello there",
    "delay": 1000
}'

And to force a Reply received after timeout scenario, increase the value of delay to something like 10000. It can be noted in the generated logs that tracing information is missing for those messages.
