I recently released a new component and it seems to be triggering change detection multiple times a second:

  // some debugging code
  ngDoCheck() {
    console.log('DO_CHECK', new Date().toLocaleTimeString());
  }

Results:

I've yet to figure out what is triggering this.

Am I reading this output correctly? Change detection is being triggered multiple times a second?

Is there any good method for figuring out what is triggering change detection in an Angular 2 application?
