const session = new inspector.Session();
session.connect();
session.post('Profiler.enable', () => {
 session.post('Profiler.start', () => {
 // Invoke business logic under measurement here...
 // some time later...
 session.post('Profiler.stop', (err, { profile }) => {
 // Write profile to disk, upload, etc.
 if (!err) {
 fs.writeFileSync('./profile.cpuprofile', JSON.stringify(profile));
 }
 });
 });
