$queryStats

Activar/desactivar la salida de registro $queryStats

MongoDB registra las operaciones $queryStats en los registros de despliegue. Por defecto, MongoDB solo registra la invocación de las operaciones $queryStats, no su resultado. Para las operaciones $queryStats que incluyen la opción transformIdentifiers, puede especificar si el resultado transformado se incluye en la entrada del registro.

Incluir la salida $queryStats en los registros proporciona más información sobre operaciones específicas de $queryStats, pero puede afectar negativamente el rendimiento del clúster debido a que las actualizaciones de los registros requieren más tiempo y recursos.

Acerca de esta tarea

Cuando MongoDB registra la salida de $queryStats, los resultados son depurados y anonimizados. La salida de $queryStats no contiene valores literales ni de campos.

Para un ejemplo de salida transformada de $queryStats, consulta Ejemplo transformado.
