MySQL 8.4 Release Notes
跟踪遥测使您能够可视化任何处理操作在服务器中处理的流程。每个操作的数据，即一个跨度(span)，包含可能的错误信息和时间数据。跟踪会为执行的COM_QUERY命令生成，包括非查询命令如COM_PING或COM_STMT_CLOSE。查询语句的跟踪还有一个相关联的 SQL 文本属性。Tracing telemetry enables you to visualize the flow of any
processing action as it is processed through your server. The data
for each action, a span, includes possible error information and
timing data. Traces are generated for COM_QUERY
commands executed, including non-query commands such as
COM_PING, or COM_STMT_CLOSE.
Query statement traces also have an associated SQL text attribute.
