A Java agent (written in C with a Java bootstrap) that generates /tmp/perf-<pid>.map symbol files for JIT-compiled methods so the Linux perf tool can profile Java applications. It includes helper shell scripts combining common perf operations with map file creation.
Use cases
- profile a Java application with Linux perf
- resolve JIT-compiled method names in perf flame graphs
- generate perf map files for a running JVM process
- find CPU hotspots in Java code with perf top
- collect stack traces from a JVM with perf record
When to choose
- you need low-overhead CPU profiling of Java on Linux with perf
- you want readable method names in perf output for JIT-compiled code
- you build flame graphs for JVM applications
When to avoid
- you profile on non-Linux platforms
- you need a maintained tool with recent releases
- you want sampling profilers with built-in symbol resolution like async-profiler
