# 解压目录中的prometheus.yml
# 简单验证，主要配置采用默认文件配置，有修改/新增处用红色标示
[root@prometheus prometheus]# vim prometheus.yml
# 全局配置
global:
  scrape_interval:     15s # 设置抓取(pull)时间间隔，默认是1m
  evaluation_interval: 15s # 设置rules评估时间间隔，默认是1m
  # scrape_timeout is set to the global default (10s).

# 告警管理配置，暂未使用，默认配置
alerting:
  alertmanagers:
  - static_configs:
    - targets:
      # - alertmanager:9093

# 加载rules，并根据设置的时间间隔定期评估，暂未使用，默认配置
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# 抓取(pull)，即监控目标配置
# 默认只有主机本身的监控配置
scrape_configs:
  # 监控目标的label（这里的监控目标只是一个metric，而不是指某特定主机，可以在特定主机取多个监控目标），在抓取的每条时间序列表中都会添加此label
  - job_name: ‘prometheus‘

    # metrics_path defaults to ‘/metrics‘
    # scheme defaults to ‘http‘.

    # 可覆盖全局配置设置的抓取间隔，由15秒重写成5秒。
    scrape_interval: 5s

    # 静态指定监控目标，暂不涉及使用一些服务发现机制发现目标
static_configs:
      - targets: [‘localhost:9090‘]
        # (opentional)再添加一个label，标识了监控目标的主机
labels:
          instance: prometheus

  - job_name: ‘linux‘
    scrape_interval: 10s
static_configs:
  # 采用node_exporter默认开放的端口
      - targets: [‘172.20.1.212:9100‘]
labels:
          instance: node1
