When I try to create an alerting policy in Stackdriver Monitoring, my custom metrics do not show up in the dropdown list. When I try to add a chart in the Stackdriver Monitoring dashboard, they show up. Is there something more I need to do to make these custom metrics alertable?
These custom metrics were created using heapster on kubernetes. I'm still on the Stackdriver Premium trial.
Here is a screenshot of the resource type list when creating a chart.
