Indexing Dispatcher Test

The Indexing Dispatchers handle flow control protocol by routing the processed items to Index servers. A dispatcher is required because a FAST Search for SharePoint 2010 installation may distribute the index over several servers. The index dispatcher needs to know which server to send which items to. If an indexing dispatcher server fails, the outstanding item batches associated with this indexing dispatcher will fail too. If you have redundant indexing dispatchers, the flow control protocol will ensure that the indexing connector resubmits the subset of item batches associated with the failing indexing dispatcher.

This test reports the number of batches processed by each indexing dispatcher.
