Docker-compose部署安装Prometheus+Alertmanager+Grafana

部署准备：
docker-compose.yml文件内容如下：

version: '2'
services:
  prometheus:
        image: prom/prometheus:latest
        container_name: prometheus
        hostname: prometheus
        restart: always
        ports:
                - '9090:9090'
        volumes:
                - '/home/app/prometheus/config:/config'
                - '/home/app/prometheus/data/prometheus:/prometheus/data'
        command:
                - '--config.file=/config/prometheus.yml'
                - '--web.enable-lifecycle'

  alertmanager:
        image: prom/alertmanager:latest
        container_name: altermanager
        hostname: altermanager
        restart: always
        ports:
                - '9093:9093'
        volumes:
                - '/home/app/prometheus/config:/config'
                - '/home/app/prometheus/data/alertmanager:/alertmanager/data'
        command:
                - '--config.file=/config/alertmanager.yml'

  grafana:
        image: grafana/grafana:latest
        container_name: grafana
        hostname: grafana
        restart: always
        ports:
                - '3000:3000'
        volumes:
                - '/home/app/grafana/config/grafana.ini:/etc/grafana/grafana.ini'
                - '/home/app/grafana/data:/var/lib/grafana'

  node-exporter:
        image: quay.io/prometheus/node-exporter
        container_name: node-exporter
        hostname: node-exporter
        restart: always
        ports:
            - "9100:9100"

由于本次部署使用本地虚拟机进行部署，所以将node-exporter直接部署在本机，如在生产环境进行部署，需将node-exporter直接部署在需要进行监控的服务器上。

创建挂载目录：

mkdir -p /home/app/prometheus/config/rules
mkdir -p /home/app/prometheus/data
mkdir -p /home/app/grafana/config
mkdir -p /home/app/grafana/data

在prometheus的config目录和rules目录中分别创建alertmanager.yml、prometheus.yml、rules.yml配置文件；在grafana的config中创建grafana.ini配置文件。

prometheus.yml文件内容如下：

global:
  # 指定Prometheus抓取应用程序数据的间隔为15秒。
  scrape_interval:     15s # By default, scrape targets every 15 seconds.
  #
  # Attach these labels to any time series or alerts when communicating with
  # external systems (federation, remote storage, Alertmanager).
  external_labels:
    monitor: 'line-monitor'

  # 普罗米修斯 规则文件
rule_files:
  - "rules/*.yml"

  # prometheus自身的Alert功能是根据我们配置的 规则文件 进行触发的，但是它并没有告警发邮件的功能，发送邮件的这件事儿是由 Alertmanager来做的
alerting:
  alertmanagers:
  - scheme: http
    static_configs:
      - targets:
        - "172.16.37.100:9093"

  # 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=<job_name>\` to any timeseries scraped from this config.
  - job_name: 'prometheus'
    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.
    static_configs:
    - targets: ['172.16.37.100:9090']

  # 后期追加mysql监控
  - job_name: 'uat-mysql'
    static_configs:
    - targets: ['172.16.37.100:9104']

  # 后期追加机器监控
  - job_name: 'node-monitor'
    static_configs:
    - targets: ['172.16.37.100:9100'] #如部署在生产环境，此ip应为部署node-monitor的服务器ip

alertmanager.yml文件内容如下：

global:
  resolve_timeout: 1m
  # The smarthost and SMTP sender used for mail notifications.
  # #smtp_smarthost: ''
  # #smtp_from: ''
  # #smtp_auth_username: ''
  # #smtp_auth_password: ''
  #
route:
  receiver: 'default-receiver'
  # The labels by which incoming alerts are grouped together. For example,
  # multiple alerts coming in for cluster=A and alertname=LatencyHigh would
  # be batched into a single group.
  # group_by: ['alertname']
  #
  # When a new group of alerts is created by an incoming alert, wait at
  # least 'group_wait' to send the initial notification.
  # This way ensures that you get multiple alerts for the same group that start
  # firing shortly after another are batched together on the first
  # notification.
  # group_wait: 5s
  # When the first notification was sent, wait 'group_interval' to send a batch
  # of new alerts that started firing for that group.
  # group_interval: 30s
  # If an alert has successfully been sent, wait 'repeat_interval' to
  # resend them.
  repeat_interval: 1m
receivers:
  - name: 'default-receiver'

rules.yml文件内容如下：

# 告警规则内容，监控demo指标是否大于等于140，如果大于则判断3是否持续30秒
groups:
- name: demo-alert
  rules:
  - alert: demo-monitor
    expr: demo > 140
    for: 3m
    labels:
      bp: hypertension
    annotations:
      company: "demo"
      desc: "current value:{{ $value }}"

grafana.ini文件内容如下：

# 配置邮件服务器
[smtp]
enabled = true
# 发件服务器
host = smtp.exmail.qq.com:465
# smtp账号
user = example@qq.com
# smtp 密码
password = ******
# 发信邮箱
from_address = gsk-portal@pharmeyes.com
# 发信人
from_name = Grafana

赋予文件夹权限，防止部署时因权限问题启动容器失败：

chmod -R 777 /home/app

至此准备工作完毕，进行部署：

cd /home/app/prometheus

浏览器访问ip:3000访问grafana，默认账号密码admin/admin：

添加data source：

选择prometheus:

输入prometheus的ip并保存：



导入grafana面板：
grafana 面板官网



此处我使用的是下载到本地后进行上传。

上传后选择对应的data source并保存：

保存后查看监控效果：

至此，已部署完成。
