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
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 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}

启动访问监控
-actuator的看板:http://localhost:port/actuator
-prometheus的看板:http://localhost:port/actuator/prometheus
配置Prometheus的对于本Springboot微服务站点的监控
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
启动成功如下
访问prometheus的应用:http://localhost:9090/
可以点击链接跳转
显示的是:http://sky-20200720fyp:8889/actuator/prometheus
说明Prometheus配置完成
然后启动Grafana
启动成功如下:初始化--启动有点久,耐性一点
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
第一次进入如下
配置Prometheus的数据源
第一步选这个管理配置菜单
第二步选这个Datasorce
第三步选这个添加新的Datasorce
第四步选这个Prometheus数据源
第五步配置Prometheus数据源的地址和名称,然后保存
第六步配置Prometheus的看板
导入对应的监控 JVM 的 Dashboard 模板,模板编号为 4701。,点击load
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
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
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
很多看板自己研究把
创建文件组
可以把监控看板移加入分类分组
