es数据二次开发统计展示

案例1

      在es查询中按照多列分组的时候 分组列的count值会越来越少 es默认隐藏了没有被分组匹配到的记录数  需要在查询的时候开启

 2.开启显示没有被分组成功的记录

    分组成功的记录加上分组missing的记录数就等于总的记录数  26932+2666=29598

 3.当实际的总数和es分组统计的条数对不上的时候 需要考虑是不是分组列的值有可能被丢失了 这个时候可以开启显示丢失

4.查看es的原始日志内容确实有10001条记录不存在CHANNEL字段

如何查看指定索引名称的创建时间

     1.命令行查询

      curl -XGET http://192.168.80.10:9200/zhouls/_settings?pretty 

      {
        "zhouls" : {
             "settings" : {
                 "index" : {
                         "creation_date" : "1488203759467",  //表示索引的创建时间
                         "uuid" : "Sppm-db_Qm-OHptOC7vznw",
                         "number_of_replicas" : "1",
                         "number_of_shards" : "5",
                         "version" : {
                              "created" : "2040399"
          }
    }

2.通过kibana查看索引的创建时间
