Springboot+actuator+prometheus+Grafana集成

2023/6/3 18:22:32

本文主要是介绍Springboot+actuator+prometheus+Grafana集成，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

本次示例以Windows示例

推荐到官网去下载：Windows版的应用程序

下载最新版 prometheus-2.37.8.windows-amd64 压缩包：解压就行

image

下载最新版 grafana-9.5.2 压缩包：解压就行

准备一个Springboot的项目：

导入相关的监控依赖

        <!--监控站点开启-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

        <!-- prometheus -->
        <dependency>
            <groupId>io.micrometer</groupId>
            <artifactId>micrometer-registry-prometheus</artifactId>
            <version>1.10.5</version>
        </dependency>


        <!--SpringSecurity 安全访问-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

springSecurity的配置

#springSecurity 配置
spring.security.user.name=root
spring.security.user.password=root
spring.security.user.roles=ADMIN

spring-actuator配置

#增加开启springboot actuator监控的配置
management:
  endpoint:
    shutdown:
      enabled: true # 开启端点
    health:
      show-details: always # 是否展示健康检查详情
  endpoints:
    web:
      exposure:
        include:
          - prometheus
          - health
  metrics:
    tags:
      application: ${spring.application.name}

springSecurity的白名单接口配置-SecurityConfig

启动访问监控

-actuator的看板:http://localhost:port/actuator

image

-prometheus的看板:http://localhost:port/actuator/prometheus

image

配置Prometheus的对于本Springboot微服务站点的监控

image

添加配置 以下内容为SpringBoot应用配置

# Prometheus  启动完成之后 http://localhost:9090/targets
# my global config
global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
  alertmanagers:
    - static_configs:
        - targets:
          # - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
# - "first_rules.yml"
# - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets: ['127.0.0.1:9090']
  ###以下内容为SpringBoot应用配置
  - job_name: 'BackStageApp'
    scrape_interval: 5s
    metrics_path: '/actuator/prometheus'
    static_configs:
      - targets: ['127.0.0.1:8889']
        labels:
          instance: "BackStageApp-prometheus"
          service: "BackStageApp-8889-prometheus"

点击这个执行：prometheus的应用

image

启动成功如下

image

访问prometheus的应用：http://localhost:9090/

image

可以点击链接跳转

image

显示的是：http://sky-20200720fyp:8889/actuator/prometheus
说明Prometheus配置完成

然后启动Grafana

image

启动成功如下：初始化--启动有点久，耐性一点

image

打开Grafana看板：http://localhost:3000/login

首次登录使用 admin:admin 然后可以设置自己的账号密码，也可以跳过Skip

image

第一次进入如下

image

配置Prometheus的数据源

第一步选这个管理配置菜单

image

第二步选这个Datasorce

image

第三步选这个添加新的Datasorce

image

第四步选这个Prometheus数据源

image

第五步配置Prometheus数据源的地址和名称，然后保存

image

image

第六步配置Prometheus的看板

image

导入对应的监控 JVM 的 Dashboard 模板，模板编号为 4701。，点击load

image
image

填写这些必填项；导入自动加载后其他可以不用管，必须选择下面的刚刚配置的prometheus数据源，然后选择import

image

第七步监控JVM

上一步点击然后选择import，会进入这个界面，什么都没有

image

选择自己项目的站点配置的application和instance就行了，刷新左上角的时间

image

很多看板自己研究把

image

创建文件组

image

可以把监控看板移加入分类分组

image
