DescribeLoadBalancerLog

最后更新时间：2021-04-09 19:58:17

    API Description

    This API is used to query the CLB layer-7 log in COS. It is applicable to public network CLB instances with HTTP or HTTPS listener configured and COS log enabled.

    Domain name for API calls: lb.api.qcloud.com

    Note that this API only supports querying COS log, but not CLS log. To query the CLS log, call the Searching for Log API, which can be used to query the forwarding logs of a CLB instance over the last three days, including logs forwarded to the RS and those directly returned from the CLB due to RS exception. Interval between requests shall be within one day.

    order No String Log sequence by timestamp. Valid values: desc and asc. Default value: desc.
    startTime No Int Time when you start querying logs using Unix timestamp (accurate to seconds). The default is 5 minutes earlier than endTime.
    endTime No Int Time when you finish querying logs using Unix timestamp (accurate to seconds). The default is the current timestamp.
    offset No Int Log offset. Value range: [0,10000].
