Prometheus+exporter+Grafana搭建监控

1.下载Prometheus 启动, 配置文件在底部。

prometheus -config.file prometheus.yml -web.listen-address :9091

2.下载node_exporter,mysql_exporter,redis_exporter

mysqld_exporter -config.my-cnf=my.cnf
redis_exporter -web.listen-address :9122 -redis.password=rediscmit
node_exporter --web.listen-address=localhost:9100

配置里的scrape_configs

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: ['localhost:9091']

  - job_name : '服务器'
    static_configs:
        - targets:
          - '127.0.0.1:9100'
