springboot+prometheus+grafana部署监控

springboot+prometheus+grafana部署监控 默认springboot服务已存在

安装版部署

环境：Centos7 64

版本：springboot2.x，prometheus-2.31.1.linux-amd64，grafana-enterprise-8.2.3.linux-amd64

---

1. Prometheus         1.1.下载解压

                官网下载地址 https://prometheus.io/download/

                选择版本 prometheus-2.31.1.linux-amd64 

                下载后解压 tar zxvf prometheus-2.31.1.linux-amd64.tar.gz

        1.2. Prometheus启动前配置

                进入目录 cd prometheus-2.31.1.linux-amd64

                编辑配置文件 vim prometheus.yml

                按以下配置修改 找到 scrape_configs 新增 job相关配置 其余配置均为默认配置不必改动

# 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:
  # The job name is added as a label `job=` to any timeseries scraped from this config.
  - job_name: "prometheus"
    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.
    static_configs:
      - targets: ["localhost:9090"]
### springboot 应用配置 对应spring.application.name
  - job_name: 'spring-boot-application'
    scrape_interval: 5s
### 对应actuator endpoints.web.base-path
    metrics_path: '/actuator/prometheus'
    static_configs:
      - targets: ['localhost:8080'] # springboot服务端口

        1.3. Prometheus启动

                nohup ./prometheus &

2. Grafana         2.1.下载解压

               官网下载地址 https://grafana.com/grafana/downloa

               或直接执行命令 wget https://dl.grafana.com/enterprise/release/grafana-enterprise-8.2.3.linux-amd64.tar.gz

               下载后解压 tar zxvf grafana-enterprise-8.2.3.linux-amd64.tar.gz

        2.2 启动

                进入目录 cd grafana-8.2.3/bin
                执行启动命令 nohup ./grafana-server &

Docker版部署

Docker version 18.09.7

---

1. Prometheus

        拉取docker镜像

        docker pull prom/prometheus

        准备一个存放配置文件的目录

        mkdir /home/prometheus

        准备prometheus.yml文件，可直接使用安装版本中修改后的配置文件 

        vim prometheus.yml  注意springboot服务路径，因为不在同一容器内所以使用物理机对应IP

      - targets: ['192.168.1.1:8080'] # springboot服务端口

       启动容器  -d 后台启动  -p 指定物理机和容器端口绑定  -v 挂载物理机目录与容器目录  参数

       docker run -d -p 9090:9090 -v /home/Prometheus/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus --config.file=/etc/prometheus/prometheus.yml

        

---

2. Grafana

        拉取docker镜像
        docker pull grafana/grafana
        启动容器
        docker run -d -p 3000:3000 grafana/grafana

---

至此安装完成，开始关联使用 Prometheus默认端口为9090 直接通过浏览器访问 http://xxx.xxx.xxx.xxx:9090 看到下图证明成功部署

Grafana默认端口为3000 同上直接浏览器访问 http://xxx.xxx.xxx.xxx:3000 看到下图证明成功部署

为Grafana配置数据源

 

URL填入你的Prometheus的url

安装包部署Prometheus与grafana在同一物理机上所以直接使用 127.0.0.1

容器部署填入物理机IP比如 192.168.1.1

然后直接拉到最下方点击这个

为Grafana配置Dashboard

        

我个人选择模板 12900，有更好的可以自行更改

到此结束，由于一些原因我展示的是无信息的效果。
