Querying Database Slow Logs¶

Function¶

This API is used to query the latest 2,000 slow query logs of an instance. Searching by keyword is not supported.

Constraints¶

This API supports GaussDB(for Cassandra) instances.
This API can be used to query only the latest 2000 slow query logs in a specified time range.

URI¶

GET https://{Endpoint}/v3/{project_id}/instances/{instance_id}/slowlog

**Table 1** Path parameters¶
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID of a tenant in a region. To obtain this value, see Obtaining a Project ID.
instance_id	Yes	String	Instance ID

**Table 2** Query parameters¶
Parameter	Mandatory	Type	Description
start_date	Yes	String	Start time in the yyyy-mm-ddThh:mm:ssZ format. T is the separator between calendar and hourly notation of time. Z indicates the time zone offset. The start time is at most 30 days earlier than the current time.
end_date	Yes	String	End time in the yyyy-mm-ddThh:mm:ssZ format. T is the separator between calendar and hourly notation of time. Z indicates the time zone offset. You can only query slow query logs generated in the last one month. The end time cannot be later than the current time.
offset	No	Integer	Index offset. Its value ranges from 0 to 1999. 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.
limit	No	Integer	Number of records to be queried. The value ranges from 1 to 100. The sum of values of limit and offset must be 2000 or lower.
node_id	No	String	Node ID. If this parameter is not specified, all nodes of the instance are queried. For details about the value, see id in table Table 10 in Querying Instances and Details.
type	No	String	SQL statement type. If this parameter is not specified, all types of SQL statements are queried. You can also specify the following log type: SELECT

Request Parameters¶

**Table 3** Request header parameters¶
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	User token

Response Parameters¶

Status code: 200

**Table 4** Response body parameters¶
Parameter	Type	Description
slow_log_list	Array of SlowlogResult objects	Information about slow query logs
total_record	Integer	Total number of records

**Table 5** SlowlogResult¶
Parameter	Type	Description
time	String	Execution time
database	String	Database which slow query logs belong to
query_sample	String	Execution syntax
type	String	SQL statement type
start_time	String	UTC time when logs are generated
