备注
If the LogBeforeDeliveryAttempts value is true, Notification Services creates a row for each notification in the NSDistributionLog table before sending the notification. The distributor then logs predelivery information, including the notification ID, notification class, distributor, and delivery request time.
Your application can also log delivery status and notification text for all or just failed notifications by configuring the LogStatusInfo Element (ADF) and LogNotificationText Element (ADF).
A LogBeforeDeliveryAttempts value of true has a negative impact on application performance because Notification Services logs information one notification at a time. Most applications still perform well, but if you need to improve performance, set this value to false. Notification Services will still log notification text and status for failed notifications.
To view log data, use the NS<NotificationClassName>NotificationDistribution 视图.
示例
The following example shows how to configure the distributor to not log basic information about each notification.
<LogBeforeDeliveryAttempts>false</LogBeforeDeliveryAttempts>
