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).
