Disabling Rebroadcasting for Historian Data Archiver

About this task

The Historian Data Archiver service rebroadcasts collector status reports to all connected clients to ensure they are immediately notified of any changes to their configuration. If you have many collectors (20 or more) pointing to a single Historian archive, you may experience network congestion.

Procedure

  1. Start the Windows Registry Editor.
  2. Navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Intellution, Inc\iHistorian\Services\DataArchiver key
  3. Create a new DWORD called RouteInterfaceStatusMsg and set it to 0 (to enable rebroadcasting, set this value to 1).
  4. Close the Windows Registry Editor.
  5. Restart the Historian Data Archiver service.
    Note: If rebroadcasting is disabled in the Historian Data Archiver service, any programs subscribed to collector status changes using Collectors.SubscribeStatus = true will no longer automatically receive collector status messages. To receive collector status messages, periodically read the Collector.Status property instead.
