• 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.
