查询日志直方图

功能介绍

查询关键词搜索条数该接口用于查询日志在某一时间段内,包含关键词的日志上报情况和日志条数统计结果。

调用方法

请参见如何调用API

URI

POST /v2/{project_id}/lts/keyword-count

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

项目ID,获取方式请参见:获取项目ID,获取账号ID,日志组ID、日志流ID

请求参数

表2 请求Header参数

参数

是否必选

参数类型

描述

X-Auth-Token

String

从IAM服务获取的用户Token,获取方式请参见:获取用户Token

Content-Type

String

该字段填为:application/json;charset=UTF-8。

表3 请求Body参数

参数

是否必选

参数类型

描述

start_time

String

开始时间

end_time

String

结束时间

step_interval

Long

时间步长,单位为毫秒(ms)。

具体请参考如下公式计算:

(end_time-start_time) / 1000 * 1000 / 60,其中 / 1000 * 1000 / 表示取整。

说明:

如果计算出的时间步长小于等于1000时,则时间步长为1000。

String

日志组ID

stream_id

String

日志流ID

key_word

String

关键词指相邻两个分词符之间的单词。

is_iterative

Boolean

日志迭代查询,默认为false(不开启迭代),true为开启迭代。

参数类型

描述

error_code

String

错误码。

error_msg

String

调用失败响应信息描述。

状态码: 500

表6 响应Body参数
