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

Operators &&, ||, AND, OR, NOT, *, ?, :, >, <, =, >=, and <= cannot be used to search for logs.
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.

Authorization Information

Each account has permissions to call all APIs, but IAM users must have the required permissions specifically assigned.

If you are using role/policy-based authorization, see the required permissions in Permissions and Supported Actions.

If you are using identity policy-based authorization, the following identity policy-based permissions are required.

start_time	Yes	String	Definition Start time Constraints The start time cannot be 30 days earlier than the current time and cannot be the same as the end time. The value of end_time must be later than that of start_time. The value is 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. Range N/A Default Value N/A

limit	Yes	Integer	Definition Number of logs queried each time Constraints N/A Range 1–100 Default Value N/A
line_num	No	String	Definition Sequence number of a single log line. The current query starts from the next log of line_num, excluding the log of line_num. Constraints This parameter is not required for the first query. The value can be obtained from the response of the last query. Range N/A Default Value N/A
operate_type	No	String	Definition Statement type Constraints N/A Range select: Only SELECT statements are queried. Default Value If this parameter is not specified, all statement types are queried.
node_id	No	String	Definition Node ID, which is used to query slow logs of a specific node. For details about the value, see field id in Table 11. Constraints N/A Range N/A Default Value If this parameter is not specified, all nodes in the instance can be queried.
keywords	No	Array of strings	Definition Full-text log search based on multiple keywords, indicating that all keywords are matched. Constraints A maximum of 10 keywords are supported. Each keyword can contain a maximum of 512 characters.
keyspace_keywords	No	Array of strings	Definition Fuzzy search for logs based on multiple keyspace keywords, indicating that at least one keyword is matched. Constraints 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	Definition Fuzzy search for logs based on multiple database table name keywords, indicating that at least one keyword is matched. Constraints 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	Definition Logs can be searched based on the maximum execution duration. Unit: ms Constraints N/A Range N/A Default Value N/A
min_cost_time	No	Integer	Definition Logs can be searched based on the minimum execution duration. Unit: ms Constraints N/A Range N/A Default Value N/A
