public function EnumQueueReaderAgentSessions (
    distributionDatabase : String, 
    publicationId : int, 
    sessionDuration : int, 
    returnOnlyErrorSessions : boolean
) : DataSet

Parameters

• distributionDatabase
  A String value that specifies the distribution database.

• publicationId

• sessionDuration
  An Int32 value that specifies the number of hours before the current time to which to limit the results.

A value of -1 returns information on the last 100 sessions, and a value of 0 returns information on all sessions.
