For digest or multicast delivery, one message can include multiple notifications. This column indicates how many notifications are sent, on average, in a digest or multicast message.

Remarks

Notification Services creates the NSSnapshotDeliveryChannels stored procedure in the instance database when you create the instance. When you update the instance, Notification Services recompiles the stored procedure.

This stored procedure is in the instance schema, which is specified by the SchemaName element of the instance configuration file (ICF). If no schema name is provided, the default schema is dbo.

The result set is ordered by the ApplicationName value, then by the DeliveryChannelName value, and then by the DistributorName value.

Permissions

Execute permissions default to members of the NSAnalysis database role, db_owner fixed database role, and sysadmin fixed server role.

Examples

The following example produces the delivery channels snapshot report for all applications that are hosted by an instance. In this example, the stored procedure (and all other instance objects) is in the StockInstance schema, as specified in the SchemaName element of the ICF.

EXEC StockInstance.NSSnapshotDeliveryChannels;
