MySQL 9.0 Release Notes
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.
Telemetry tracing is implemented in:
MySQL Enterprise Edition Telemetry Component
MySQL Enterprise Edition Client
MySQL Connectors
