Doc Type: Bug Fix
Doc Text:
Cause: Recent versions of the prometheus-adapter metrics server send additional pod-specific metrics, which confuse the Vertical Pod Autoscaler (VPA) recommender. Consequence: When the extra metrics are received by the VPA, it logs a warning message. Depending upon the size of the cluster, the VPA recommender can log many megabytes of log messages per day of this form: Error adding metric sample for container {{example-pod-name} POD}: KeyError: {{example-pod-name} POD} Fix: The new version of the VPA recognizes and ignores the extra metrics.
