#事件监控

##初始化mysql数据库
####在mysql上创建db及表，注意表名也是kube_eventer
	create database kube_eventer;
	use kube_eventer;

create table kube_eventer
	(
    id               bigint(20)   not null auto_increment primary key comment 'event primary key',
    name             varchar(64)  not null default '' comment 'event name',
    namespace        varchar(64)  not null default '' comment 'event namespace',
    event_id         varchar(64)  not null default '' comment 'event_id',
    type             varchar(64)  not null default '' comment 'event type Warning or Normal',
    reason           varchar(64)  not null default '' comment 'event reason',
    message          text  not null  comment 'event message' ,
    kind             varchar(64)  not null default '' comment 'event kind' ,
    first_occurrence_time   varchar(64)    not null default '' comment 'event first occurrence time',
    last_occurrence_time    varchar(64)    not null default '' comment 'event last occurrence time',
    unique index event_id_index (event_id)
	) ENGINE = InnoDB default CHARSET = utf8 comment ='Event info tables';
