0 likes154 views
The document details the AHF Insights tool within the Oracle AHF stack, which provides a unified reporting and diagnostic analysis platform for Oracle databases. AHF Insights consolidates data from various components into a web-based graphical interface, allowing for root cause analysis through system performance metrics, logs, and configuration reviews. Key features include system topology visualization, event timelines, best practice compliance checks, and detailed reporting functionalities for effective database management.

- 3. Confidential – Oracle Internal 3 • AHF Insights provides a bird's eye view of the entire system with the ability to further drill down for root cause analysis. • Previously, results from different AHF components were not available in a single dashboard making it challenging to combine and correlate. To mitigate this, AHF Insights provides a web-based graphical user interface, which does not require a web server to host the web pages, for all diagnostic data collectors and analyzers that are part of AHF Kit. • AHF performs a diagnostic collection for a given period to analyze the performance of database systems from: • Configuration • Environment Topology • Metrics • Logs • This diagnostic data collected from the system passes through AHF Insights and produce an offline report.
