I cannot seem to figure out how to get certain metrics from GCP into Stackdriver (google monitoring) in a usable way. They can be viewed using Stackdriver's "Metrics Explorer" tool, but not saved into a graph or alerting policy. As a specific example, only a handful of the metrics outlined in this table are available:
https://cloud.google.com/monitoring/api/metrics_gcp#gcp-container
Again, I can use the "Metrics Explorer" tool to immediately visualize any one of them in an ad-hoc graph, but I cannot create an alerting policy or any sort of persistent monitoring for anything except for CPU Usage, Disk Usage, Page Faults, and Used Memory. Does anyone know how to get one of these metrics (such as container/cpu/usage_time) into an alerting policy?
Metrics Explorer includes access to more metrics than are currently available for alerting. We're working on addressing this both for UIs and APIs. Please stay tuned to release notes. Thanks for using Stackdriver!
