No dashboard to display changing group of items
We created a discovery rule that identifies the system bandwidth limits / QOS rules and, based on that, creates prototype items with custom keys qos.interface, qos.status, gos.downstream, qos.upstream. There is no issue with the keys and data, but there is no convenient way of displaying changing keys. The rule/key may be removed, renamed, or a new one may be added. With 70+ hosts, we try to make all dashboards change automatically. The only so-so dashboard widget to follow up with changing group of keys is "Data overview", there is no alternative that would support tags or groups of items. That's the only reason why we are not upgrading to version 7 (Data overview is deprecated and removed in version 7)
