Total System Analyzer

Total System Analyzer (TSA) was a performance monitoring tool for z/OS, designed to identify high-activity systems and program modules. It included the Problem Program Evaluator (PPE) to enhance module performance analysis. TSA is no longer a standalone product; its functionality is now part of BMC's MAINVIEW.

TSA's architecture involved data collection agents on z/OS systems, a central processing component, and a reporting module. Communication would have occurred over standard z/OS communication protocols. While specific commands are unavailable due to the product's discontinuation, it likely involved commands to initiate analysis, specify target systems, and generate reports.

Configuration likely involved specifying data sources and report parameters. It likely supported standard z/OS authentication methods, such as RACF, ACF2, or Top Secret. Alternatives include IBM Z Performance and Capacity Analytics, CA SYSVIEW Performance Management, and IntelliMagic Vision for z/OS.

These products offer comprehensive monitoring and analysis features for z/OS environments. TSA helped optimize system performance, reduce resource consumption, and improve application response times. Its integration with z/OS security mechanisms ensured secure operation.

The tool provided data-driven insights into system behavior, enabling informed decision-making regarding resource allocation and system tuning. This proactive approach helped prevent performance issues.
