# TIBCO Mainframe Logger - Overview

For mainframe logging in TIBCO products such as TIBCO Substation ES, TIBCO Interface for CICS/IMS/RED, TIBCO Mainframe RED, and other products such as messaging, TIBCO provides the TIBCO Mainframe Logger component. The TIBCO Mainframe Logger is generically referred to as the "Mainframe Logger" in this guide and it covers all aspects of logging for TIBCO's products and user applications. This component provides a logging facility for applications running either in a single-system or in a multisystem IBM Sysplex.

TIBCO Mainframe Logger forwards events and messages to IBM z/OS System Logger. The IBM z/OS System Logger files are streams of data, and TIBCO Mainframe Logger efficiently writes data to these files. TIBCO Mainframe Logger can write thousands of messages every second to the IBM z/OS System Logger. The IBM z/OS System Logger is a Multiple Virtual Storage (MVS) component and is referred as the "System Logger" throughout this guide.

TIBCO Mainframe Logger provides two components:

1. A browser to view current log records in the log structures.
2. An extract component where,
   - Data extracted from the mainframe logger, such as logged events, statistical information and more, can be routed to off-host storage media.
   - Statistical information can be sent to analytics systems for monitoring and analysis of near real-time transactions, and events of the IBM z/OS system.
