Small Homebrew tap for Java-related profiling tools.
Usage:
brew tap qwwdfsad/tap
brew install async-profiler
brew install hsdisFormula for the binary installation of async-profiler
that adds asprof to the corresponding */bin/* and provides a convenience wrapper over converter.jar.
Installation:
brew tap qwwdfsad/tap
brew install async-profiler
Usage:
asprof -f profile.html -d 20 <pid|JPS name>
asprof-converter jfr2flame --bci profile.jfr profile.html
Additionaly, formula installs libasyncProfiler.dylib into Homebrew prefix ($HOMEBREW_PREFIX/lib/) for the easier discovery.
To further use async-profiler with JMH's -prof async seamlessly,
consider adding the installed dylib into DYLD_LIBRARY_PATH. The brew installation will hint you on that.
Formula for the installation of hsdis -- Hotspot disassembly library for Java:
brew tap qwwdfsad/tap
brew install hsdis
The formula builds it from OpenJDK sources against Capstone with the effortless-hsdis and installs the hsdis dylib into Homebrew keg.
The installer will give you a hint what to do next:
hsdis was installed into /opt/homebrew/opt/hsdis/libexec/lib/hsdis-aarch64.dylib
In order to make it locateable by the JVM, you can either add it to Java's lib folder ($JAVA_HOME/lib/)
or add a lib path to the $DYLD_LIBRARY_PATH:
$ echo 'export DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH:/opt/homebrew/opt/hsdis/libexec/lib/' >> ~/.zshrc
