Wilfred Spiegelenburg commented on YUNIKORN-1385:
-------------------------------------------------
The only real crude measurement you would be able to get is the time from
allocation to delete of the pod. One is defined by the creation of the
allocation in the scheduler. The second is defined by the delete of the pod
from K8s. There is no need for an extension of anything but the application
object. We already track the peak usage as {{maxUsedResource}} in the
application.
A simple new tracker for resource seconds can be added to the application. The
only change is for the delete part. This could be easily implemented as a
single Jira.

> Currently the "Used Resource" for a given application reported at Yunikorn
> GUI is actually the snapshot of the resources currently allocated to the
> application. We need to provide visibility to how much resources an
> application has used so far, and it would be important to report how much
> total resources is used by the application.
> The unit of resources used can be memoryseconds/vcoreseconds like how Hadoop
> Yarn does in its app summary report. However, there is more complexity with
> K8s which supports different instance types (Hadoop Yarn does support
> multiple instance types but its app summary report ignored instance types).
> It would be nice to report how much resource is used for each instance types
> used by an application.
> This is a top level Jira for this new feature. Subtask jira will be created
> when we work on it.
