Oracle AHF Insights 23c: Deeper Diagnostic Insights for your Oracle Database - OCYatra July 2023
0 likes24 views
AHF Insights provides a unified reporting and correlation tool that collects diagnostic data from an AHF stack and generates an offline report. It captures information on system topology, insights like events and issues, and allows drilling down into specific components for root cause analysis. The report includes sections on the cluster summary, resources, databases, metrics, best practices, system changes, software recommendations, and detailed parameters for databases and kernels. Users can filter, search, expand and collapse different sections, and view timeline graphs and configuration details to analyze system performance and issues.

- 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.
