Flame Graphs for MySQL DBAs
summary
Shows how to generate and use Brendan Gregg’s FlameGraph SVG visualizations (from github.com/brendangregg/FlameGraph) to analyze MySQL performance by converting profiling outputs—perf, bpftrace, Performance Schema, EXPLAIN, or any path+metric CSV—into the required format. Covers different flame-graph types (CPU, off‑CPU, memory, differential), tools and collection techniques for profiling MySQL internals, and several real-world examples where flame graphs pinpointed and helped resolve issues.
