The scaling configured according to cpu usage: enter image description here

On the chart it's about 8 minutes between upscaling and 2 mins between downscalings. enter image description here

We cannot upscale faster because an instance requires ~5min to launch, however I'd like to have downscaling with similar delay too. Other variables:

Default Cooldown 600

Health Check Grace Period 400

What's configured wrong here?

In your decrease logic, increase the value for "consecutive periods...".

That should induce delay in your ASG shrink actions.

    but '4 consecutive periods of 300 seconds' is 20 minutes, why we have only two?

  • @Putnik probably because the "remove 2" condition is being hit, so 2 are being removed at relatively the same time.
