Application Services detail
For each Application Service (AppService) currently identified to the NameServer, there is a unique table of displayed values that appears on the Operational Status page. The following table briefly describes each of these fields. Also, note these additional points about the relationship of these fields to each other and to data presented in the Summary section:
*An individually registered broker can support multiple Application Services. Therefore, you might see several AppService detail sections associated with a NameServer instance, but only a small total number reported in the Number of Brokers field in the Summary section.
*In an Application Services detail section, the value that appears in the Requests Received field reflects a total number of requests for this service. However, each broker identified as supporting a client request to an Application Service maintains its own individual Requests Directed total.
*If an active broker goes down or is unavailable, any AppService details associated with that broker will no longer appear. If the broker reregisters, its total Requests Directed count will be reset to zero.
The following table identifies and describes the fields and their display-only details that appear in each AppService section of the Operational Status page. Many of these values originate from the configuration settings stored in the ubroker.properties file.

Field
Description
Requests Received
The number of client requests received for this Application Service. This count is maintained when one or more brokers are registered to support the Application Service. The count is reset when the Application Service is first identified to the NameServer.
Broker
The name of the broker that is capable of fulfilling the connection between the requesting client and the Application Service. When more than one broker is servicing the same Application Service, each new broker's data is appended to the individual AppService details section.
Host
The broker's host machine name and numeric address.
Weight
The priority weight assigned to the Unified Broker instance for the purpose of load balancing.
Requests Directed
The total number of client connection requests for the Application Service as directed by the NameServer to the broker instance.This count is maintained while the broker remains registered. If the broker is stopped or times out, the broker's count is reset to zero when the broker next runs. There is a separate counter for each Application Service that the broker supports.
UUID
The unique number for the Unified Broker instance.
Port
The TCP/IP port number that the broker listens on to pick up client connection requests.
Timeout
The amount of time, in seconds, that elapses between the "keep alive" messages that the broker sends to the resource as part of a broker's registration retry entry process.
