Hi, VPA will always collect and store history while it's running. With Prometheus VPA can load history from before it started.
For example lets say that:
A
.VerticalPodAutoscaler
object with deployment A
as its target.Without loading history from Prometheus:
A
is based on <1 day of history.With loading history from Prometheus:
There is some nuance what happens if you start VPA in the cluster on day 0 but don't create any VPA objects until day 8. I think in that case VPA gathers all data so it's likely to provide recommendation based on 8 days of data if you create a VerticalPodAutoscaler
object on day 8. But I think it only saves data associated with a VerticalPodAutoscaler
object in checkpoints, so it might have less data if vpa recommender pod is restarted in the meantime.
Please reopen if this doesn't answer your question.
Hi guys,
I don't find any documentation about the historical data with VPA Recommender, I have a simple question, Can I have historical information with the only metric server? without need to install the Prometheus? if yes, how long this historical information can be?
Thank you.
