Steps to Reproduce
Enable pod-level metrics in Retina.
Observe metrics for active pods.
Delete some pods.
Continue to observe the metrics display.
Expected Behavior
Metrics data and graphs should only be displayed for active pods. Deleted pods should no longer appear in the live metrics display.
Actual Behavior
Metrics data and graphs are still being displayed for pods that have been deleted.
@abhipatwari17 feel free to contribute, there is a way to fix this. Whenever we get a delete notification, we can loop over all the existing timeseries and check if this is used in a dimension and delete that specific time series. This will help in reducing cardinality greatly !
