Universal Messaging interfaces (see TCP Interfaces, IP Multicast and Shared Memory
) allow users to connect to a Realm using various protocols and ports on specific physical Network interfaces on the host machine. Interfaces are also available to users through the Universal Messaging Administration API and can provide useful status information regarding user connections.
The Enterprise manager provides a summary of this status information for each interface. This section will describe the status information available for each interface.
To view status information for an interface, you must first select the 'Comms' tab for the Realm you want to view. This tab contains the interface configurations as well as Multicast and Shared Memory configurations Select the interface you wish to view from the list of interfaces in the 'Interfaces'. By selecting the desired interface, you will be presented with a number of panels, one of which is labeled 'Status'. This panel is shown in the image below.
The interface status panel has a section that describes the details of the interface status information. The status information contains 6 values, each of which is described below.
- The number of idle threads, calculated as the total threads from the interface accept threads pool - the number of threads from the pool currently accepting connections. Corresponds to available threads
- The total number of successful connections made to this interface
- The total number of failed connection attempts made to this interface
- The average time it takes a connection to authenticate with the realm server
Pool Exhausted Count
- The number of times that the interface thread pool has had no threads left to service incoming connection requests. When this count increases, you should increase the number of accept threads (see Interface Configuration
) for the interface
Ave Pool Wait
- The average time that a client connection has to wait for the accept thread pool to provide an available thread. Like the Pool Exhausted count, this is a good indicator that the number of accept threads for an interface is too low and needs to be increased
The status panel also shows 2 graphs that depict connection attempts (successful connections are shown in yellow, failed connection attempts are shown in red) and authentication times (average authentication times are shown in yellow, and the last authentication time is shown in red).
