Use when you need to set up Java application profiling to detect and measure performance issues — including trusted preinstalled async-profiler v4.x setup, problem-driven profiling (CPU, memory, threading, GC, I/O), interactive profiling scripts, JFR integration with Java 25 (JEP 518, JEP 520), or collecting profiling data with flamegraphs and JFR recordings. This should trigger for requests such as Improve the code with profiling; Apply Profiling; Refactor the code with profiling; Add…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Java Profiling Workflow / Step 1 / Collect data to measure potential issues Set up the Java profiling detection phase using a trusted preinstalled async-profiler v4.x, problem-driven interactive profiling scripts, and comprehensive data collection for CPU hotspots, memory leaks, lock contention, GC issues, and I/O bottlenecks. Uses JEP 518 (Cooperative Sampling) and JEP 520 (Method Timing) for reduced overhead. **What is covered in this Skill?** - Run application with profiling JVM flags (run-java-process-for-profiling.sh) - Interactive profiling script (profiler/scripts/profile-java-process.sh) — copy exact template - Directory structure: profiler/scripts/, profiler/results/, profiler/current/ - Automated OS/architecture detection and trusted preinstalled async-profiler validation - CPU, memory, lock, GC, I/O profiling modes - Flamegraph and JFR output with timestamped results **Scope:** Use the exact bash script templates without modification or interpretation. ## Constraints Copy bash scripts exactly from templates. Ensure JVM flags are applied for profiling compatibility. Verify Java processes are running before attaching profiler. …

How to install
mdr add jabrena/plinth/161-java-profiling-detect@sha256:dd7cf315dcaf5ed5The line at the top of this page pins the label v0.19.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
