Skills 101: Foglight | Finding the “Why” Behind Performance Changes

Wednesday, April 22, 11:00am - 12:00pm (EDT)

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.
Designed for existing Foglight users, this session shows how time-aligned visibility enables faster, evidence-driven root cause analysis.
Topics include:

Using Change Tracking to align configuration, schema, execution plan, and system changes with performance timelines
Correlating performance degradation with specific environmental or workload changes
Applying Comparison to identify new, missing, or altered SQL, users, and workloads across time periods or instances
Combining Change Tracking and Comparison to validate root cause using evidence rather than assumptions
Reducing investigation time by focusing analysis on what changed and what is different

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