# Mainframe HUB

The Mainframe HUB is an essential part of the Mainframe Logger. When the Mainframe Logger is activated, users get a consolidated view of all operations and executions across all the respective TIBCO systems, executing the core mainframe product stack. When this Mainframe Logger is not activated, data is written to the current output media.

There are many advantages of using the Mainframe Logger with TIBCO Substation ES, TIBCO Mainframe RED or user batch programs. You can collect, view, and extract the TIBCO product executions, service executions and the run-time events.

The Mainframe HUB is identified by all applications by its name. A set of three logger streams, such as logs, traces and statistics, are associated with a HUB. This is the key when deciding which HUBs will be used for your environment and your applications.

Note: The Mainframe HUB should run continuously so that all the applications can use its facilities. If the Mainframe HUB is stopped due to some reason, either stop all the applications, including Substation ES regions, CICS and IMS regions using it, or recycle the applications after the HUB restarts.
