Any run times shorter than 15 minutes may not be reported.
The CloudHealth Kubernetes agent takes a snapshot every 15 mins via the API. The API lists all nodes/pods which are currently running. Once the container has been stopped, it typically is not returned in this API call. If you have very short-running pods (~1 min in runtime), the platform would typically miss collecting data for this pod unless the agent happened to run at the same time the pod was running.
