Parameter description

**Table 1** Parameter description
Name	Mandatory	Description
project_id	Yes	Project ID of a tenant in a region. For details about how to obtain the project ID, see Obtaining a Project ID.
instance_id	Yes	ID of the instance to be queried.
start_date	Yes	Start time in the "yyyy-mm-ddThh:mm:ssZ" format. T is the separator between the calendar and the hourly notation of time. Z indicates the time zone offset. For example, in the Beijing time zone, the time zone offset is shown as +0800.
end_date	Yes	End time in the "yyyy-mm-ddThh:mm:ssZ" format. T is the separator between the calendar and the hourly notation of time. Z indicates the time zone offset. For example, in the Beijing time zone, the time zone offset is shown as +0800. You can only query slow logs generated within a month.
offset	No	Index offset. If offset is set to N, the resource query starts from the N+1 piece of data. The value is 0 by default, indicating that the query starts from the first piece of data. The value cannot be a negative number. The latest 2,000 slow query logs can be queried. The value of offset plus the value of limit must be no more than 2,000. For example, if the value of offset is set to 1900, and the value of limit cannot be greater than 100.
limit	No	Number of records (query results) displayed on each page. The number ranges from 1 to 100. The default value is 10.
