MySQL 8.4 Release Notes
MySQL Enterprise Edition 8.4 generates OTel trace data on Linux platforms.
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
