title: Kubernetes autoscaler targetCPUUtilizationPercentage
body: <p>I'm defining this autoscaler with kubernetes and GCE and I'm wondering what exactly should I specify for <code>targetCPUUtilizationPercentage</code>. That target points to what exactly? Is it the total CPU in my cluster? When the pods referenced in this autoscaler consume more than <code>targetCPUUtilizationPercentage</code> what happens?</p>
