Raise monitoring.prow.k8s.io prometheus retention to 90d
Raise monitoring.prow.k8s.io prometheus retention to 90d

I don't have any insight into how much disk prometheus is using
right now at 30d retention, and am unsure of what performance
impact this would have on performance.

I'd like to ultimately raise to a year
