使用 nohup 或 disown 如果你要让某个进程运行在后台。

写数据查询表达式的问题

情境：每个客户端都有自己的号码，客户端大约每3分钟发送一次心跳到服务器。每次心跳都会发送日志到ELK，字段包括ouyu-number（客户号码，6位数字）、reg_time（发送心跳的时间，时间格式是2019-07-18 13:59:08这样）。
要求：统计最近24小时至最近4小时发送过心跳，但是最近4小时以内没有发送心跳的号码。
不知道Discover的Filter里是否可以写这样的语句。
我自己在Dev Tools的Console里想写类似的语句：
GET /_search

{

    "query": {

        "query_string" : {

            "default_field": "ouyu-number",

            "query":{"@timestamp":"now-4h" TO "now"}

        }

    }

}
不知道应该怎么写。

    这个索引的mapping：
    {
    
  "mapping": {
    
    "properties": {
    
      "@timestamp": {
    
        "type": "date"
    
      },
    
      "@version": {
    
        "type": "text",
    
        "fields": {
    
          "keyword": {
    
            "type": "keyword",
    
            "ignore_above": 256
    
          }
    
        }
    
      },
    
      "message": {
    
        "type": "text",
    
        "fields": {
    
          "keyword": {
    
            "type": "keyword",
    
            "ignore_above": 256
    
          }
    
        }
    
      },
    
      "ouyu-number": {

        "fields": {
    
          "keyword": {
    
            "type": "keyword",
    
            "ignore_above": 256
    
          }
    
        }
    
      },
    
      "ouyu-version": {
    
        "type": "text",
    
        "fields": {
    
          "keyword": {
    
            "type": "keyword",

        "fields": {
    
          "keyword": {
    
            "type": "keyword",
    
            "ignore_above": 256
    
          }
    
        }
    
      },
    
      "reg_time": {
    
        "type": "date",
    
        "fields": {
    
          "keyword": {
    
            "type": "keyword",
    
            "ignore_above": 256
    
          }
    
        },

        "fields": {

            "type": "keyword",
    
            "ignore_above": 256
    
          }
    
        }
    
      },
    
      "tags": {
    
        "type": "text",
    
        "fields": {
    
          "keyword": {
    
            "type": "keyword",
    
            "ignore_above": 256
    
          }
    
        }
    
      }
    
    }
    
  }
    
}

    根据您的提示我这样写语句：
    GET /bj-sip_register/_search
    
{
    
  "size":0,
    
  "aggs": {
    
    "number": {
    
      "filter": {
    
        "range": {
    
          "@timestamp": {
    
            "gte":"now-24h/h",
    
            "lt":"now-4h/h"
    
          }
    
        }
    
      },
    
      "aggs": {
    
        "x": {
    
          "terms": {
    
            "field": "ouyu-number"
    
          }
    
        }
    
      }
    
    }
    
  }
    
}
