Prometheus 告警规则

Prometheus 告警规则概念：

警报规则允许您根据 Prometheus 表达式语言表达式定义警报条件，并将有关触发警报的通知发送到外部服务。每当警报表达式在给定的时间点产生一个或多个向量元素时，警报对于这些元素的标签集算作活动。
类似于记录规则, 告警规则(Alerting rule) 也定义在独立的文件中, 而后由 Prometheus 在 rule_files 配置段中加载配置如下：

rule_files:
  - alerting_rules/*.yml          # 告警规则文件路径

Prometheus指标含义：

选项	含义
- group	配置顶级，用于定义一个监控组
- name	规则名称
- rules	规则
- alert	告警规则名称
- expr	表达式基于PromQL表达式告警触发条件，用于计算是否有时间序列满足该条件
- for	评估等待时间，在等待时间状态为pending，满足时长告警状态为firing，恢复则为inactive状态
- lables	自定义标签
- annotations	用于指定一组附加信息，比如用于描述告警详细信息的文字等，annotations的内容在告警产生时会一同作为参数发送到Alertmanager。summary描述告警的概要信息，description用于描述告警的详细信息。同时Alertmanager的UI也会根据这两个标签值，显示告警信息。
