获取内核慢日志信息。

调用方法

请参见如何调用API

URI

POST /v3/{project_id}/instances/{instance_id}/clickhouse/slow-logs

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

租户在某一Region下的project ID。

获取方法请参见获取项目ID

instance_id

String

其中,T指某个时间的开始;Z指时区偏移量,例如偏移1个小时显示为+0100。

end_time

String

开始时间,格式为“yyyy-mm-ddThh:mm:ssZ”。

其中,T指某个时间的开始;Z指时区偏移量,例如偏移1个小时显示为+0100。

limit
