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.

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

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
