Querying Slow Query Logs of a GeminiDB Cassandra Instance

Function

This API is used to query slow query logs of GeminiDB Cassandra instances. Searching for slow query logs by keyword is supported.

Constraints

The following operators are supported: &&, ||, AND, OR, NOT, *, ?, :, >, <, =, ≥, and ≤
The query must be within the period specified by start_time and end_time.
The value of line_num must be obtained from the log information returned for the last query. This parameter is optional for the first query.
A maximum of 100 records can be queried on each page, and slow query logs can be stored for a maximum of 30 days.

URI

POST https://{Endpoint}/v3/{project_id}/cassandra/instances/{instance_id}/slow-logs

**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.

Request Parameters

**Table 2** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	User token.

**Table 3** Request body parameters
Parameter	Mandatory	Type	Description
start_time	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 cannot be 30 days earlier than the current time.
end_time	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. The end time cannot be later than the current time.
limit	Yes	Integer	Number of logs to be queried each time. The maximum value is 100.
line_num	No	String	Sequence number of a log event. This parameter is not required for the first query, but is required for the next query. The value can be obtained from the response of the last query. The current query starts from the next log of line_num, excluding the log of line_num.
operate_type	No	String	Statement type. If this parameter is left empty, all statement types are queried. The value can be select.
node_id	No	String	Node ID. If this parameter is left blank, all nodes in the instance can be queried. For details about the value, see field id in Table 10.
keywords	No	Array of strings	Full-text log search based on multiple keywords, indicating that all keywords are matched. A maximum of 10 keywords are supported. Each keyword can contain a maximum of 512 characters.
keyspace_keywords	No	Array of strings	Fuzzy search for logs based on multiple keyspace keywords, indicating that at least one keyword is matched. Only fuzzy search by keyword prefix is supported. A maximum of 10 keywords are supported. Each keyword can contain a maximum of 48 characters.
table_keywords	No	Array of strings	Fuzzy search for logs based on multiple database table name keywords, indicating that at least one keyword is matched. Only fuzzy search by keyword prefix is supported. A maximum of 10 keywords are supported. Each keyword can contain a maximum of 48 characters.
max_cost_time	No	Integer	Logs can be searched based on the maximum execution duration. Unit: ms
min_cost_time	No	Integer	Logs can be searched based on the minimum execution duration. Unit: ms

node_id	String	Node ID.
whole_message	String	Statement.
operate_type	String	Statement type.
cost_time	Integer	Execution time. Unit: ms
keyspace	String	Database keyspace.
table	String	Table name.
log_time	String	UTC time when a log is generated. The format is yyyy-mm-ddThh:mm:ssZ. T is the separator between calendar and hourly notation of time. Z indicates the time zone offset.
line_num	String	Sequence number of a log event.
