Comentarios

La MaximumKilobytes propiedad representa el límite de tamaño del archivo de registro de eventos. Cuando el registro de eventos alcanza el límite de tamaño, el valor configurado OverflowAction determina si se descartan nuevas entradas o si las entradas nuevas sobrescriben las entradas anteriores.

Nota

Esta propiedad representa un valor de configuración para el registro de eventos representado por esta instancia. Cuando el registro de eventos alcanza su tamaño máximo, esta propiedad especifica cómo el sistema operativo controla las nuevas entradas escritas por todos los orígenes de eventos registrados para el registro de eventos.
