1. You can follow the public issue report <https://issuetracker.google.com/37368857>where engineering is working on reducing the health checks. The reason you still see some after disabling is because there are multiple sources performing health checks <https://stackoverflow.com/questions/42841697/google-app-engine-health-checks-spamming-app> on your instances, and disabling only stops one of the sources.
2. App Engine Flexible instances are charged for their resources by the hour <https://cloud.google.com/appengine/pricing#flexible-environment-instances>. Therefore, setting a Manual instance will cause your instance to run constantly, even when there is no traffic and it is doing no work. Not turning your instance down during idle time is the reason for your higher bill. Consider using Automatic or Basic scaling <https://cloud.google.com/appengine/docs/standard/python/config/appref#scaling_elements> to minimize the time your instances are running, in turn reducing your bill. - Note that there are other resources <https://cloud.google.com/appengine/pricing#other-resources>that can cause your bill to be higher, it is recommended to view your bill <https://support.google.com/cloud/answer/6293699?hl=en> to better understand the breakdown of charges. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
