### Built in Profilers You can see which are available to you and properly configured via ` ./jmh.sh -lprof` - Linux perf c2c profiler (shared C2C/HITM analysis. Allows you to track down cache-line contentions) - DTrace profile provider + PrintAssembly Profiler (OSX) - async-profiler profiler provider (flamegraphs, jfr output) - Linux perf + PrintAssembly Profiler (perfasm) - Simple and naive Java stack profiler - Linux perf Statistics - Linux perf statistics, normalized by operation count - Windows xperf + PrintAssembly Profiler - Pauses profiler - JIT compiler profiling via standard MBeans - Classloader profiling via standard MBeans - GC profiling via standard MBeans - Safepoints profiler - Java Flight Recorder profiler ### External Custom Profilers can be plugged in. See https://github.com/nicoulaj/jmh-utils/tree/master/jmh-profilers for examples of: - flight-recorder - heapaudit - honest-profiler - jhiccup - solaris-studio - yourkit Here you might find the following profiler interesting https://github.com/cache2k/cache2k-benchmark/tree/master/jmh-suite/src/main/java/org/cache2k/benchmark/jmh - ForcedGcMemoryProfiler ### I like to sometimes dump heaps and gc logs and hotspot logs from benchmarks. If you do too, you might find the following interesting. - https://github.com/mgm3746/garbagecat (cmd line gc log analysis/reccomendation tool) - https://www.eclipse.org/mat/ (optionally cmd line) - JOverflow from https://www.oracle.com/java/technologies/jdk-mission-control.html (great GUI option, and if one digs and pulls into the depths, great hidden cmd line option) - https://jxray.com/ (cmd line heap dump / reccomendation tool) - https://github.com/AdoptOpenJDK/jitwatch (Log analyser and visualiser for the HotSpot JIT compiler.) -- This is an automated message from the Apache Git Service.
