The entire benefit of App Engine is that it handles scaling for you and uses many other metrics other than CPU to scale instances as described in the documentation <https://cloud.google.com/appengine/docs/flexible/nodejs/an-overview-of-app-engine#instance_scaling> .
Looking at the source code of the appengine-config-transformer <https://github.com/GoogleCloudPlatform/appengine-config-transformer/blob/master/yaml_conversion/lib/google/appengine/api/appinfo.py#L293> it does mention the existence of hidden scaling settings that indeed match that of the available Stackdriver Monitoring metrics for App Engine <https://cloud.google.com/monitoring/api/metrics#gcp-appengine>. You can therefore try using these in your app.yaml <https://cloud.google.com/appengine/docs/flexible/nodejs/configuring-your-app-with-app-yaml#automatic_scaling> configuration file to adjust your App Engine scaling settings at your own risk (as there are no documented limits for these settings). If you require the need to have full control over your scaling instances, you may instead want to take a look at Google Container Engine. <https://cloud.google.com/container-engine/> -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
