Story Points:3
We want to be able to record flamegraph for our utests execution.
This mechanism would be enabled if the PR contains a specific label.
A tentative to record these flamegraphs have been done within: https://github.com/nuxeo/nuxeo-lts/pull/1356
It mainly consists to download the async-profiler binary:
stage('Download Async-Profiler') {
steps {
container('maven') {
sh "wget -O /tmp/async-profiler-2.9-linux-x64.tar.gz https://github.com/jvm-profiling-tools/async-profiler/releases/download/v2.9/async-profiler-2.9-linux-x64.tar.gz"
sh "mkdir -p ${ASYNC_PROFILER_ROOT_PATH}"
sh "tar -C ${ASYNC_PROFILER_ROOT_PATH} --strip-components=1 -xzvf /tmp/async-profiler-2.9-linux-x64.tar.gz async-profiler-2.9-linux-x64"
// now the profiler is available at:
// /tmp/async-profiler/build/libasyncProfiler.so
}
}
}
And then set the async-profiler java agent to the surefire arguments:
MAVEN_ARGS = "${MAVEN_ARGS} ${MAVEN_FAIL_ARGS} -Dit.memory.argLine=\"-Xms4g -Xmx4g -agentpath:${ASYNC_PROFILER_ROOT_PATH}/build/libasyncProfiler.so=start,event=cpu,file=\\\${project.build.directory}/flamegraph.html\""
