A five-phase sequence diagram orchestrating process lifecycle management through synchronous calls between User, Intent Engine, Process Manager, Process Monitor, CPU Analyzer, Memory Analyzer, and the psutil OS library. Phase 1 captures on-demand user commands routed through Intent Engine to Process Manager; Phase 2 collects live process data via psutil; Phase 3 analyzes CPU and memory consumption using dedicated analyzers; Phase 4 handles process termination with error handling for PermissionError and ProcessNotFound exceptions; Phase 5 implements periodic polling on a scheduled interval. This architecture demonstrates separation of concerns, error resilience, and real-time system observability essential for production process management tools. Fork this diagram on Diagrams.so to customize phases, add new analyzers, or adapt error handling for your monitoring stack. The activation bars and lifelines clearly show call sequences and component responsibilities across the entire workflow.
