¿Por qué el valor de la esperanza de vida de la página a veces excepcionalmente alta (4,3 m)?

Question

Mi valor de la esperanza de vida de la página generalmente está en un rango de 3000 - 10000.

Pero como puede ver en la muestra de pequeñas datos a continuación, hay valores regulares de aproximadamente 4,3 millones. Obtengo esos valores usando TyPEPERF y almacenan directamente los resultados en una tabla de SQL Server utilizando una conexión SYSTEM-DSN.

Comando:

 typeperf -f SQL -s 1.2.3.4 -cf "C:\SQL-PerfMon\SqlCtr.cfg" -si 250 -o SQL:PerfMonLogDSN!MyServer -sc 6

El archivo de configuración sqlctr.cfg contiene esta línea:

\MSSQL$InstanceName:Buffer Manager\Page life expectancy

Debido a que los valores de 4,3 millones son tan diferentes / más altos que los otros, sospecho algún tipo de error / error. Interesante es que hace algunas semanas, este valor apareció mucho más, entonces en estos días. Mientras tanto, aparece aproximadamente 1 vez por día. Lamentablemente, arruina completamente las tablas en los informes que conduzco.

Nos enfrentamos a este problema en muchos de nuestros servidores SQL.

¿De dónde viene?

Answer 1

4294847 es similar 4294967295 con algunos dígitos afeitados, y 4294967295 es un valor bien conocido (0xFFFFFFFFF).Esto me hace sospechar un infriso entero durante una sustracción en la herramienta que usa para leer los valores ( TYPEPERF ).PLE es un contador complejo que las aplicaciones necesitan considerar adecuadamente la base y el intervalo de tiempo transcurrido para calcular el valor, consulte tipos de contadores , y obtener el cómputo incorrecto no es inaudito.

Intenta ver si el valor impar se muestra también en Logman Rastros recolectados, o directamente en perfmon .
