TDSQL Boundless provides the log delivery feature. Through log delivery, slow logs from TDSQL Boundless instances can be collected and delivered to CLS (Cloud Log Service) for analysis, to quickly monitor and locate business issues. This article describes how to enable or disable the log delivery feature via the console.
Prerequisites
Before using this feature, please ensure you have enabled CLS.
Definition of Slow Logs
Field Value
Type
Description
TIMESTAMP
-
The reserved field of CLS represents the log generation time.
InstanceId
String
Database Instance ID, for example tdsql3-xxx.
SqlText
String
The executed SQL statement, example: DROP DATABASE IF EXISTS db1.
UserHost
String
The client address from which the operation is executed, example: 172...10.
UserName
String
The username that performed the operation, example: root.
Database
String
Database name, example: mysql.
QueryTime
Double
SQL execution time, unit: seconds.
LockTime
Double
The total time spent from the start of lock waiting to the actual acquisition of the lock and completion of the operation, unit: seconds.
NodeId
String
Database node name, example: hybrid-2.
RowsExamined
Long
The number of rows successfully parsed and processed during query or operation execution.
RowsSent
Long
The number of rows actually returned to the client after query or operation execution.
RpcTime
Double
The total duration of RPC calls for executing SQL statements, unit: seconds.
StorageRpcTime
Double
The total time spent on all RPC communications between compute and storage during SQL statement execution, unit: seconds.
RpcRetryDelayTime
Double
The total time spent waiting for RPC retry intervals during SQL statement execution, unit: seconds.
TransactionId
String
The transaction ID of the SQL statement. All SQL statements within a transaction share the same transaction ID.

Log topic operations
A log topic is the basic unit for log data collection, storage, retrieval, and analysis. You can select an existing log topic or create a log topic.
Logset Operation
A logset is a classification of log topics to help you manage log topics. You can select an existing logset or create a logset.
Logset
Select an existing logset: You can filter existing logsets in the search box to categorize slow log shipping.
Create a logset: You can create a new logset to categorize slow log shipping. It is recommended to use the naming format "tdstore_logset_custom" for the logset.
Log Topic
Select an existing log topic: This option is available only when the log topic operation selects an existing logset. You can filter log topics under the selected logset in the search box.
Create a log topic: Create a new log topic under the selected logset. The naming format for the log topic should be tdstore_topic_custom.
4. After slow log shipping is successfully enabled, you can see that slow log shipping is enabled under Log Shipping. Click the log topic name to jump to the CLS console for subsequent analysis and management.
