前言一、SpringBoot配置
1.修改springboot工程2.测试springboot提供监控 二、部署Prometheus
1.安装docker2.下载docker镜像3. 编写prometheus配置文件4. 启动prometheus5. 测试prometheus 三、部署Grafana
1. 下载grafana镜像2. 运行grafana3. 测试访问grafana4. 关联prometheus
4.1. 添加数据源4.2. 使用模板4.3. 附汉化后模板JSON
前言
Prometheus是一个根据应用的metrics来进行监控的开源工具。相信很多工程都在使用它来进行监控，有关详细介绍可以查看官网：https://prometheus.io/docs/introduction/overview/。
Grafana是一个开源监控利器，官网地址：https://grafana.com/。
引入依赖
maven:
io.micrometer micrometer-registry-prometheus
gradle:
api group: 'io.micrometer', name: 'micrometer-registry-prometheus'
在application.properties中开启Actuator
management.endpoints.web.exposure.include=* # 或者 management.endpoints.web.exposure.include=prometheus2.测试springboot提供监控
访问访问http://192.168.100.88:7901/demo/actuator/prometheus
为了简单，这里使用docker部署
1.安装docker如果安装过了，跳过，这里以centos7中安装20版本为例
# 查看已安装docker
yum list installed | grep docker
rpm -qa | grep docker
# 卸载旧版本（如果之前安装过的话）
yum remove docker
docker-client
docker-client-latest
docker-common
docker-latest
docker-latest-logrotate
docker-logrotate
docker-engine
# 安装所需的软件包。
# yum-utils 提供了 yum-config-manager
# 并且 device mapper 存储驱动程序需要 device-mapper-persistent-data 和 lvm2
yum install -y yum-utils device-mapper-persistent-data lvm2
# 设置yum安装源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# 查看可用版本有哪些
yum list docker-ce --showduplicates | sort -r
# 安装
yum install -y docker-ce docker-ce-cli containerd.io
# yum install -y docker-ce- docker-ce-cli- containerd.io
# 启动 Docker 并设置开机自启
systemctl start docker
systemctl enable docker
2.下载docker镜像
docker pull prome/prometheus:v2.32.13. 编写prometheus配置文件
prometheus.yml:
scrape_configs: # 可随意指定 - job_name: 'spring' # 多久采集一次数据 scrape_interval: 15s # 采集时的超时时间 scrape_timeout: 10s # 采集的路径 metrics_path: ' <此处修改为springboot项目的context-path>/actuator/prometheus' # 采集服务的地址，设置成Springboot应用所在服务器的具体地址 static_configs: - targets: ['192.168.100.88:7901']4. 启动prometheus
假设配置文件在/opt/prometheus下，启动docker:
docker run -d -p 9090:9090 -v /opt/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml prome/prometheus:v2.32.1 --config.file=/etc/prometheus/prometheus.yml5. 测试prometheus
测试地址：http://172.16.10.171:9090/
随便输入一个访问actuator/prometheus页面出现的指标，如jvm_gc_live_data_size_bytes，如下图所示：
1. 下载grafana镜像Grafana是一个开源的度量分析与可视化套件，纯Javascript开发的前端工具，通过访问库（如InfluxDB），展示自定义报表、显示图表等。它的UI十分灵活，有丰富的插件和模板，功能强大。一般用在时序数据的监控方面。
docker pull grafana/grafana:8.3.32. 运行grafana
docker run -d -p 3000:3000 grafana/grafana:8.3.33. 测试访问grafana
访问http://172.16.10.171:3000，默认用户名和密码为admin/admin
很多优秀的模板可以在https://grafana.com/grafana/dashboards/查找。这里使用springboot的模板地址为：https://grafana.com/grafana/dashboards/15425。
将JSON下载下来
将JSON文件导入
效果：
可以对JSON文件汉化，
汉化后效果：
