我可以想象你可以像这样听SIGUSR2...

// https://nodejs.org/api/process.html#signal-events
process.on('SIGUSR2', () => {
  console.log('SIGUSR2 signal received');

  const inspector = require('node:inspector');
  const fs = require('node:fs');
  const session = new inspector.Session();
  session.connect();

  // https://nodejs.org/api/inspector.html#cpu-profiler_1
  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));
        }
      });
    });
}); 


});
