ElasticSearch预警服务-Watcher详解-管理Watcher服务
1.监听
Watcher相关的数据存储在.watches索引中，该索引具有只读权限，
必须通过API来创建，更新和删除。

GET .watches/_search
{
        "fields" : [], 
        "query" : {"match_all" : { } }
}

 2.通过Kibana监控Watcher历史数据

在kibana中配置 setting>indices
    配置.watch_history*索引
    时间字段选择 trigger_event.schedule.triggered_time
    在Discover页面查询相关数据   

   
3.查询历史记录

GET .watch_history-2015.05.11/_search
{
        "query" : { "match_all" : {} }
}

 查询所有的历史记录

GET .watch_history*/_search
{
        "query" : { "match" : { "watch_id": "rss_watch"}}
}

 4.查询所有的state数据

GET .watch_history*/_search
{
        "query" : { "match" : { "state": "throttled"}}
}

 5.查询时间段的触发记录

GET .watch_history*/_search
{
  "query": {
    "filtered": {
      "query": {
        "query_string": {
          "query": "*",
          "analyze_wildcard": true
        }
      },
      "filter": {
        "bool": {
          "must": [
            {
              "range": {
                "trigger_event.schedule.scheduled_time": {
                  "gte": 1430438400000,
                  "lte": 1431820800000
                }
              }
            }
          ],
          "must_not": []
        }
      }
    }
  },
  "size": 0,
  "aggs": {
    "2": {
      "date_histogram": {
        "field": "trigger_event.schedule.scheduled_time",
        "interval": "30s",
        "pre_zone": "-07:00",
        "pre_zone_adjust_large_interval": true,
        "min_doc_count": 1,
        "extended_bounds": {
          "min": 1430438400000,
          "max": 1431820800000
        }
      }
    }
  }
}

 6.管理历史记录索引

PUT _watcher/watch/manage_history
{
  "metadata": {
    "keep_history_days": 7
  },
  "trigger": {
    "schedule": {
      "interval": "1d"
    }
  },
  "input": {
    "simple": {}
  },
  "condition": {
    "always": {}
  },
  "transform": {
    "script" : "return [ dateToDelete : '/.watch_history-' + ctx.execution_time.minusDays(ctx.metadata.keep_history_days).toString('yyyy.MM.dd') ]"
  },
  "actions": {
    "delete_old_index": {
      "webhook": {
        "method": "DELETE",
        "host": "localhost",
        "port": 9200,
        "path": "{{ctx.payload.dateToDelete}}"
      }
    }
  }
}
