Issue with fetching metrics - WARNING - Was not able to get history range for cluster

[ashliakhov]

Hey team, I'm executing krr simple --namespace dev --history_duration 48 against one of my clusters, but it returns this warning regarding history fetch failure

What am I doing wrong?

...

WARNING  Was not able to get history range for cluster arn:aws:eks:eu-east-1:123456:cluster/dev-cluster. This is not critical, will try continue.
...

In the end it returns recommendations successfully, but I guess they are not respecting historical metrics :(

Thanks!

hi @ashliakhov

The error message might be misleading
KRR tries to run a query, to check if there's enough history in the cluster to run a scan (the minimum is 5 hours)
If this check fails, this warning is printed, and KRR continues as usual.

The recommendations you get should be valid

I've created a PR #351 to make the message more clear.
