This application require Eureka service registry

cd discovery-server
mvn clean install -Dmaven.test.skip
docker build -t discovery-service:1.0.1 .
docker run -d --name discovery-service -p 8761:8761 discovery-service:1.0.1

Run http://localhost:8761

1. UserService

cd user-service

mvn clean install -Dmaven.test.skip
sh ./script/start.sh

4. Demo UI

To capture traces from above microservice run the sample-ui application using below commands

npm install -g serve
serve -l 9090 ui

Open http://localhost:9090 and perform actions that will capture traces to signoz

View traces, logs and metrics:

• View the metrics in signoz, go to http://localhost:3301/application
