配置文件

指标说明

1、Prometheus以scrape_interval规则周期性从监控目标上收集数据，然后将数据存储到本地存储上。

2、scrape_interval可以设定全局也可以设定单个metrics。

3、Prometheus以evaluation_interval规则周期性对告警规则做计算，然后更新告警状态。

4、evaluation_interval只有设定在全局。

global：全局配置

alerting：告警配置

rule_files：告警规则

scrape_configs：配置数据源，称为target，每个target用job_name命名。又分为静态配置和服务发现
