Realm Connections
When a Universal Messaging client connects to a realm server, the server maintains information about the connection. For more information, see Connection Information), which is available through the Universal Messaging Administration API. The API also provides mechanisms for receiving notifications when connections are added and deleted. See the code example "Connection Watch" for an illustration of using this in the Administration API.
The Universal Messaging Enterprise Manager enables you to view the connections on a realm as well as to view specific information about each connection, such as the last event sent or received, and the rate of events sent and received from each connection.
To view the current realm connections, select a realm node from the namespace, and then click Monitoring > Connections. The Enterprise Manager displays a panel containing a table of connections, as shown in the image below. The table lists all the clients connected to the realm server
The connections table contains the following information:
*protocol - The protocol used in the connection.
*user - The name of the connected user.
*host - The host machine from which the user is connecting.
*connection - The local connection ID, defined as hostname:local_port.
*language - The language that the client application is using.
*name - The name of the operating system on which the client application is running.
*build number - the build number of the client API.
To disconnect a connection and then make the client reconnect again, select a connection in the table and click Bounce.
To view more details about a specific connection, double-click the connection in the table or click Show Details. The connection details panel is shown in the image below.
