Ensure `max_connections` Is Capacity-Planned and Monitored
Descripción
max_connections must be sized from instance capacity, per-connection memory, application pool limits, administrative reserve, and measured peak concurrency, and monitored with current and rejected connections.
Cómo se verifica
Método de auditoría: Revisión manual
Esta recomendación no se puede verificar automáticamente. Un escaneo la lista con estas instrucciones cuando se pasa --include-manual.
SHOW GLOBAL VARIABLES LIKE 'max_connections'; SHOW GLOBAL STATUS LIKE 'Max_used_connections'; SHOW GLOBAL STATUS LIKE 'Threads_connected'; SHOW GLOBAL STATUS LIKE 'Connection_errors_max_connections'; Review a representative peak period and confirm an approved capacity calculation, coordinated application/Gateway pool totals, an administrative reserve, and alerts for utilization and rejected connections.
Cómo se corrige
Método de corrección: Guía o parche de infraestructura
Calculate the approved limit from workload and memory evidence, coordinate application pool limits, and persist it through a TDSQL custom parameter template. Do not apply a generic value such as 2048 without capacity testing.
