參數

• tracerTokenId
  An Int32 value that specifies the ID value that uniquely identifies the tracer token.

傳回值

A DataSet object that contains the following columns.

Column	Data type	Description
distributor_latency	Int64	Number of seconds between the tracer token record being committed at the Publisher and being committed at the Distributor.
subscriber	String	Name of the Subscriber that received the tracer token.
subscriber_db	String	Name of the subscription database into which the tracer token record was inserted.
subscriber_latency	Int64	Number of seconds between the tracer token record being committed at the Distributor and being committed at the Subscriber.
overall_latency	Int64	Number of seconds between the tracer token record being committed at the Publisher and being committed at the Subscriber.

備註

One row is returned for each subscription that received the tracer token record. Call EnumTracerTokens to get the tracer tokens inserted into the monitored publication.

The EnumTracerTokenHistory method is only valid for transactional publications.

The EnumTracerTokenHistory method can only be called by members of the db_owner or replmonitor fixed database roles in the distribution database.

Calling EnumTracerTokenHistory is equivalent to executing sp_helptracertokenhistory (Transact-SQL).

The EnumTracerTokenHistory method is available only with SQL Server 2005.

This namespace, class, or member is supported only in version 2.0 of the .NET Framework.
