./bin/dtrace-java-record-stack is not working #87

Open anianna96 opened 3 years ago

anianna96 commented 3 years ago

Ran ./bin/dtrace-java-record-stack but the command does not work. I think the dtrace command inside the ./bin/dtrace-java-record-stack is not used properly.

cat /tmp/dtrace-25840.data Usage /usr/bin/dtrace [--help] [-h | -G] [-C [-I]] -s File.d [-o ]
