title: Why won't Google app engine observe my health check interval?
body: <p>I am using Google App Engine Flexible environment (Node.js)</p>
  
  <p>I have my own custom healthcheck implementation, however it is getting run every single second rather than the 8 seconds I have configured below.</p>
  
  <p>Since my healthcheck does some things that are non trivial I would like to remove some load from my server by increasing the interval</p>
  
  <pre><code>health_check:
    enable_health_check: True
    check_interval_sec: 8
    unhealthy_threshold: 10
    healthy_threshold: 2
    timeout_sec: 8
  </code></pre>
  
  <p>Any idea why my interval won't work?</p>
