Scrape interval

[xobot42]

Hello. Could you help me to understand. How often hpa get metrics from prometheus-adapter for change number of pods. Does it depends on global scrape_interval in prometheus/victroria-metrics? For example If global scrape equal 1m it means that hpa react after 1min for changes?

There are two intervals that this will depend on:

1. Prometheus scrape interval for Kubelet metrics
2. Kube-controller-manager HPA sync period

The theoretical maximum time it would take to the HPA to react would be the sum of these two intervals.
