# Java Profiling Workflow / Step 2 / Analyze profiling data Analyze profiling results systematically: inventory results (flamegraphs, JFR, GC logs, thread dumps), identify problems (memory leaks, CPU hotspots, threading issues), document findings using standardized templates (profiling-problem-analysis-YYYYMMDD.md, profiling-solutions-YYYYMMDD.md), prioritize using Impact/Effort scores, and correlate multiple profiling files for validation. **What is covered in this Skill?** - Inventory: scan profiler/results/ for allocation-flamegraph, heatmap-cpu, memory-leak, *.jfr, *.log, *.txt - Problem identification: memory (leaks, excessive allocations, GC pressure), performance (CPU hotspots, blocking), threading (deadlocks, contention, pool saturation) - Documentation: docs/profiling-problem-analysis-YYYYMMDD.md, docs/profiling-solutions-YYYYMMDD.md - Prioritization: Impact (1–5) / Effort (1–5), focus on high priority first - Tools: async-profiler, JFR, JProfiler/YourKit, GCViewer, flamegraphs, heatmaps **Scope:** Validate profiling results represent realistic load scenarios. Cross-reference multiple files. Include quantitative metrics. ## Constraints Validate profiling results represent realistic load before analysis. Document assumptions and limitations. Cross-reference multiple files. - **VALIDATE**: Ensure profiling results represent realistic load scenarios before analysis - **DOCUMENT**: Record assumptions and limitations in analysis reports - **CROSS-REFERENCE**: Use m...
