Finding the “Why” Behind Performance Changes with Foglight

Ever chase a performance issue only to realize something changed… but no one knows exactly what, when, or why? In this Skills 101 session, we’ll focus on how Foglight’s Change Tracking and Comparison capabilities within Performance Investigator help teams move from suspicion to proof when performance deviates.

This session is designed for existing Foglight users who want faster, evidence-driven root cause analysis using time-aligned visibility.

In this session, we’ll explore how to:

• Use Change Tracking to align configuration, schema, execution plan, and system changes directly to performance timelines
• Correlate performance degradation with specific environmental or workload changes
• Apply Comparison to identify new, missing, or altered SQL, users, and workloads across time periods or instances
• Combine Change Tracking and Comparison to validate root cause using evidence instead of assumptions
• Reduce investigation time by focusing analysis on what changed and what’s different

By the end of the session, you’ll have a clear, repeatable method for diagnosing performance issues using Foglight’s Change Tracking and Comparison tools.
