How to run
In order to run system
Build necessary docker containers:
sbt projects_service/docker:publishLocal
sbt opentelemetry/docker:publishLocal
Run specific system setup using docker compose. For instance :
docker-compose -f docker-compose/opentelemetry-prometheus-docker-compose.yml up -d
After, run load testing to simulate user traffic
sbt Gatling/test
Check target APM or any monitoring tool and verify telemetry has been sent.
Stop environment using docker compose:
