The Trex Server Layer

This layer helps administrators to figure out the following:

• The number of indices that were available in a location other than the default directory;
• The number of indices that were valid;
• The number of valid indexes in the Fast Search infrastructure module;
• The maximum size allocated to the global dictionary and the current size of the global dictionary.
• The current status of each index;
• How effective was each index in search and query operations?
• What is the current state of the queues within each queue group?
• What is the current state of documents in the queues that are within each queue group?
• How many threads are allocated to each service of the SAP TREX server?
• How many threads are currently running, idle, suspended etc for each service?
