Publication Information, Warnings (Snapshot Publication, SQL Server 2005 and Later)
The Warnings tab is available for Distributors that are running SQL Server 2005 and later versions. The Warnings tab allows you to perform the following tasks for the selected publication:
Specify thresholds associated with warnings.
Define alerts associated with warnings.
By default, Replication Monitor displays warnings for uninitialized subscriptions: a status of Uninitialized subscription is displayed as a warning in the Status column of pages that include subscription information. For snapshot publications, you can also specify that imminent subscription expiration results in a warning by setting the option Warn if a subscription will expire within the threshold. If the specified threshold is met or exceeded, the subscription status is displayed as Expiring soon/Expired (unless an issue with a higher priority needs to be displayed).
In addition to displaying a warning in Replication Monitor, reaching a threshold can also trigger an alert. Alerts are defined by clicking Configure Alerts and providing information in the Configure Replication Alerts dialog box.
