LGTM

Please note the labels in the panel is getting truncated right after the second character.

It may be best to either put the labels either at the bottom or have two panels per row.

Please remove the phrase 'Metrics' from the string Metrics Overview in the changelog.

We have kept the same behavior with the previous visualization. We totally agreed on your point and we have created separate issue for that as well. Once all redis migration PRs are approved and merged we will work on that issue.
