Expetune is a z/OS performance analysis tool designed to identify and resolve performance bottlenecks in application environments. The architecture comprises several key components:
* **Data Extraction Module:** This module extracts data from SMF records and other data sources. * **Analysis Engine:** The analysis engine processes the extracted data to identify performance bottlenecks and resource consumption patterns.
It uses algorithms to detect anomalies and generate performance metrics. * **Reporting Module:** The reporting module generates reports and visualizations based on the analysis results. It supports various output formats, including text, CSV, and HTML.
* **Configuration Manager:** The configuration manager allows administrators to configure data sources, analysis parameters, and reporting options. These components communicate through internal APIs and data queues. The tool uses z/OS security features, including access control lists (ACLs) and role-based access control (RBAC), to protect sensitive performance data.
Expetune can generate FreezeFrame, Application Performance Analyzer, and Strobe measurement jobs. It audits COBOL load libraries, VSAM dataset usage, CICS SIT options, and PL/1 source libraries to identify potential performance issues. Competing products include IBM OMEGAMON and CA SYSVIEW.
Expetune differentiates itself by offering a focused set of features tailored to identifying and resolving performance issues in specific application environments. The administrative interface is a command-line interface (CLI).
