配置prometheus路径下的prometheus.yml文件，我们可以在global中配置包括prometheus抓取数据、验证rule的时间间隔；在rule_files中配置rule_file的地址；scrape_configs中设置数据源。

global:  # How frequently to scrape targets by default.  [ scrape_interval: <duration> | default = 1m ]  # How long until a scrape request times out.  [ scrape_timeout: <duration> | default = 10s ]  # How frequently to evaluate rules.  [ evaluation_interval: <duration> | default = 1m ]  # The labels to add to any time series or alerts when communicating with  # external systems (federation, remote storage, Alertmanager).
