Tasa de recopilación de elementos no utilizados

Microsoft.JEE.PerformanceHealth.GarbageCollectorRateMonitor (UnitMonitor)

El monitor de rendimiento para la tasa de recopilación de elementos no utilizados de un servidor de aplicaciones.

Knowledge Base article:

Resumen

El monitor de rendimiento de la tasa de recopilación de elementos no utilizados realiza un seguimiento de la velocidad a la que se producen las recopilaciones de elementos no utilizados en la Máquina virtual Java asociada con el servidor de aplicaciones.

Causas

Un estado incorrecto indica que el recolector de elementos no utilizados ha superado el umbral supervisado configurado para el servidor de aplicaciones.

Resoluciones

Inicie el servidor de aplicaciones con una configuración de memoria mayor.
Mueva algunas aplicaciones implementadas a otro servidor de aplicaciones.
