I want to use the Autoscaler for Managed Instance Groups with a custom metric I write to from App Engine.
However the Autoscaler documentation states:
The standard metric must contain data for a gce_instance monitored resource. You can use the timeSeries.list API call to verify whether a specific metric exports data for this resource.
Can I create the metric as type "gce_instance" and write to it from GAE? Or did I misinterpret the documentation section and I can just go ahead without special consideration for this section?
Google App Engine (GAE) users should use "global" as a resource type because the resource type gae_app is not permitted in custom metrics. You are good to create custom metric as "global" and write to it from GAE. You can find this documentation as a reference.
