A java agent to generate /tmp/perf-.map files for JITted methods for use with perf
cmake .
make
Add -agentpath:<dir>/libperfmap.so to the java command line.
Note: If perf top still doesn't show any detailled info it's probably because of a permission problem. A common solution is
to run the java program as a regular user with the agent enabled and then run a chown root /tmp/perf-<pid>.map to make
the file accessible for the root user. Then run perf top as root. You could use the following script to do that:
sudo chown root /tmp/perf-$1.map
sudo perf top
