Prometheus

按照官网的提示安装好Docker并配置好国内Docker加速
Docker：https://docs.docker.com/engine/install/centos/
国内加速：https://yeasy.gitbooks.io/docker_practice/install/mirror.html

提前准备好配置文件

  1. #创建一个存放Prometheus配置文件的目录
  2. mkdir -p /docker/prometheus
  3. #主配置文件
  4. vim /docker/prometheus/prometheus.yml
  5. # my global config
  6. global:
  7.   scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  8.   evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  9.   # scrape_timeout is set to the global default (10s).
  11. # Alertmanager configuration
  12. alerting:
  13.   alertmanagers:
  14.   - static_configs:
  15.     - targets:
  16.       # - alertmanager:9093
  18. # Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
  19. rule_files:
  20.   # - "first_rules.yml"
  21.   # - "second_rules.yml"
  23. # A scrape configuration containing exactly one endpoint to scrape:
  24. # Here it's Prometheus itself.
  25. scrape_configs:
  26.   # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  27.   - job_name: 'prometheus'
  29.     # metrics_path defaults to '/metrics'
  30.     # scheme defaults to 'http'.
  32.     static_configs:
  33.     - targets: ['10.0.0.220:9090']

使用Docker启动

  1. docker run --name prometheus -d -p 9090:9090 \
  2.     -v /docker/prometheus/:/etc/prometheus/ \
  3.     prom/prometheus

浏览器打开对应的服务器IP:9090即可

Grafana

官方提供的Web UI太简陋，用来调试和直接查询时够用，但无法作为一个强大的监控系统，引入Grafana提供Web界面支持

  1. docker run --name grafana -d -p 3000:3000  \
  2.   -v /docker/grafana:/var/lib/grafana  \
  3.   grafana/grafana
