Spring Boot + Prometheus + Grafana

This Repository integrates SpringBoot + Prometheus + Grafana

Step 1 : run spring boot application

i provided a script build.sh to simply create package and run application. default port is 8088.

notes : configuration file for spring boot v1.5 and v2 is different. so there are two directories for each version. and also prometheus config. so based on your project version check directories.

in existing projects add these maven dependencies

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
        
<!--this is for spring boot v2, for v1.5 check bellow-->
<dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-core</artifactId>
</dependency>
<!--this is for spring boot v1.5-->
<dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-spring-legacy</artifactId>
</dependency>
        

<dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
</dependency>

and add these configurations to application.yml

management:
  endpoints:
    web:
      exposure:
        include: "*"

Step 2 : integrate Prometheus

$ docker pull prom/prometheus

and create a configuration file for prometheus named prometheus.yml like the file in project. and run it like this.

$ docker run -d --name prometheus -p 9090:9090 \
-v PATH_TO_PROJECT/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus --config.file=/etc/prometheus/prometheus.yml

Step 3 : integrate Grafana

$ docker pull grafana/grafana

and after that run it like this

$ docker run -d --name grafana -p 3000:3000 grafana/grafana

and finally integrate Grafana with Prometheus. you should go to HOST_IP:3000 (Grafana panel) and login with admin/admin auth. after that you should add prometheus as datasource and enter HOST_IP:PORT of prometheus. and after that go to manage dashboards and import this dashboard link to dashboard for v2 or link to dashboard for v1.5

have fun :))
