Abstract: Automatically generating TN3270 emulator configuration files for implementing communication sessions. A hardware master console (HMC) is data mined to determine a status for one or more data center mainframe entities that include one or more central processing centers (CPCs), sysplexes, logical partitions (LPARs), or various combinations thereof. The data mining also identifies one or more relationships between the data center mainframe entities. The one or more HMCs are periodically polled to update the status for the one or more data center mainframe entities. The updated status and the one or more identified relationships are incorporated into a graphical user interface that provides a navigational aid for navigating to each of a plurality of data center mainframe entities.
