3.ElasticSearch预警服务-Watcher详解-Schedule配置
Watcher服务详解-定时器的设定关于Schedule配置选择，Watcher提供了丰富的时间语法支持，采用UTC时间，来我们一起看下如何设置:
支持的设置方式：
hourly:按小时周期设置
daily:按天周期设置
weekly:按周周期设置
monthly:按月周期设置
yearly:按年周期设置
cron:Cron表达式设置
interval :固定周期设置
详细案例：
1.按小时
每小时过30分钟执行
"trigger" : {"schedule" : {"hourly" : { "minute" : 30 }}}
指定时间执行,每小时第0,15,30,45分钟执行
"trigger" : {"schedule" : {"hourly" : { "minute" : [ 0, 15, 30, 45 ] }}}
2.按天
每天下午5点执行
"trigger" : {"schedule" : {"daily" : { "at" : "17:00" }}}
"trigger" : {"schedule" : {"daily" : { "at" { "hour" : 17, "minute" : 0 } }
每天00:00, 12:00, 17:00 执行
"trigger" : {"schedule" : {"daily" : { "at" : [ "midnight", "noon", "17:00" ] }}}
每天00:00, 00:30, 12:00, 12:30, 17:00,17:30执行
"trigger" : {"schedule" : {"daily" : {"at" {"hour" : [ 0, 12, 17 ]"minute" : }}
3.按星期
每周五下午5点执行
"trigger" : {"schedule" : {"weekly" : { "on" : "friday", "at" : "17:00" } }}
每周二12:00，周五17:00执行
"trigger" : {"schedule" : {"weekly" : [{ "on" : "tuesday", "at" : "noon" },{ "on" : "friday", "at" : "17:00" }]}}
每周二，周五的12:00,17:00执行
"trigger" : {"schedule" : {"weekly" : {"on" : [ "tuesday", "friday" ]"at" : [ "noon", "17:00" ]}}
4.按月
每月10号12:00执行
"trigger" : {"schedule" : {"monthly" : { "on" : 10, "at" : "noon" }}}
每月10号12:00,20号17:00执行
"trigger" : {"schedule" : {"monthly" : [{ "on" : 10, "at" : "noon" },{ "on" : 20, "at" : "17:00" }]}
每月10号，20号的0:00,12:00执行
"trigger" : {"schedule" : {"monthly" : {"on" : [ 10, 20 ]"at" : [ "midnight", "noon" ]}}
5.按年
"trigger" : {"schedule" : {"yearly" : { "in" : "january", "on" : 10, "at" : "noon" } }}
"trigger" : {"schedule" : {"yearly" : [{ "in" : "january", "on" : 10, "at" : "noon" },{ "in" : "july", "on" : 20, "at" : "17:00" }]}
"trigger" : {"schedule" : {"yearly" : {"in: : [ "jan", "dec" ],"on" : [ 10, 20 ],"at" : [ "midnight", "noon" ]}}
6.Cron表达式
"trigger" : {"schedule" : { "cron" : "0 0 12 * * ?"} }
7.固定周期设置
5秒
"trigger" : { "schedule" : {"interval" : "5s" } }
5分钟
"trigger" : { "schedule" : {"interval" : "5m" } }
5小时
"trigger" : { "schedule" : {"interval" : "5h" } }
5天
