alarm表结构
名称 属性 描述
alarm_id string 告警id
enabled int 告警是否开启
name string 告警名称
type string 告警类型，可选的值有: gnocchi_resources_threshold, threshold
severity string 告警级别
description string 告警描述信息
timestamp decimal 告警时间
user_id string 用户id
project_id string 项目id
state string 告警状态，可选的值有: alarm, insufficient data, ok
state_timestamp decimal 告警状态时间
ok_actions array 状态为正常状态ok时执行的action列表，每个元素是一个字符串
alarm_actions array 状态为告警状态alarm时执行的action列表，每个元素是一个字符串
insufficient_data_actions array 状态为数据不足状态insufficient_data时执行的action列表，每个元素是一个字符串
repeat_actions int 是否重复执行action
rule string 告警规则，根据不同的告警类型，有不同的告警规则。经过处理后可以转换为字典。
time_constraints string

3 alarm_history资源模型
alarm_history表的主要作用就是记录每次告警状态发生改变时的记录
MariaDB [aodh]> desc alarm_history;
+--------------+---------------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+--------------+---------------+------+-----+---------+-------+
| event_id | varchar(128) | NO | PRI | NULL | |

| timestamp | decimal(20,6) | YES | | NULL | |
| severity | varchar(50) | YES | | NULL | |
+--------------+---------------+------+-----+---------+-------+
