安装启动Grafana

brew install Grafana
brew services start grafana

启动后，通过http://localhost:3000/访问，用户名和密码都是admin，如图：

Grafana

安装启动Prometheus

brew install prometheus
brew services start prometheus

安装启动node_exporter

brew install node_exporter
brew services start node_exporter

启动后，可以通过http://localhost:9100/查看，如图：

node_exporter

安装启动mysqld_exporter

docker pull prom/mysqld-exporter
docker run -d -p 9104:9104 -e DATA_SOURCE_NAME="username:passwd@(localhost:3306)/dbname" prom/mysqld-exporter

安装启动cadvisor

#安装
docker pull google/cadvisor:latest
#启动
docker run \
  --volume=/:/rootfs:ro \
  --volume=/var/run:/var/run:rw \
  --volume=/sys:/sys:ro \
  --volume=/var/lib/docker/:/var/lib/docker:ro \
  --volume=/dev/disk/:/dev/disk:ro \
  --publish=8080:8080 \
  --detach=true \
  --name=cadvisor \
  google/cadvisor:latest

启动后，访问http://localhost:8080/metrics，查看暴露给Prometheus的数据。
访问http://localhost:8080/containers/，查看各个container的数据，如图：

配置Prometheus

配置文件默认放在/usr/local/etc/prometheus.yml，重启服务生效

scrape_configs:
  - job_name: "prometheus"
    static_configs:
    - targets: ["localhost:9090"]
      labels:
        instance: prometheus
  - job_name: "node_exporter"
    static_configs:
    - targets: ["localhost:9100"]
      labels:
        instance: node_exporter
  - job_name: mysqld_exporter
    static_configs:
      - targets: ['localhost:9104']
        labels:
          instance: mysqld_exporter
  - job_name: 'cadvisor'
    static_configs:
      - targets: ['127.0.0.1:8080']
        labels:
          instance: cadvisor

启动后，可以通过http://localhost:9090/打开，查询go_threads语句，如图：
