MySQL 8.4 Reference Manual Including MySQL NDB Cluster 8.4

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
