@mgiota, do you know if we already have that mapping between these values (metrics.alert.inventory.threshold, onActiveAlert) and a human-readable from the rule registry, maybe?

@fkanout Yep there's a way. I quickly opened a draft PR #132404. Once I open it for a review, I will add you as a reviewer
