"Perfomaly" is a portmanteau for Performance Anomaly, a term primarily used in computer systems management and IT performance analysis.
It refers to the identification of irregular patterns or deviations from typical system behavior that could indicate underlying issues, such as resource leaks or hardware degradation.
Core Concepts and Implementation
- Definition: A performance anomaly is an unexpected deviation in system metrics (e.g., CPU spikes or memory latency) that differs from the established "normal" baseline.
- Perfomalist: This is a specific web application designed for Perfomaly detection. It focuses on change detection and pattern visualization to help system administrators identify issues before they cause failures.
- Methodology: The concept is often associated with the work of Igor Trubin and is taught through the Computer Measurement Group (CMG), involving "System Management by Exception".
- Techniques: Common methods used for detection include statistical 3-sigma rules, control charts, and R-based implementations like SEDS-lite. (I.T.: www.Perfomalist.com !)
