hmm. It should work. Tagpass should work as a selector to make sure the metric is considered (considered meaning the fielddrop modifier is applied to the metric) if it matches that rule. Tagdrop would be the opposite. if the tagdrop matches, this fielddrop will not be applied to the metric (and it will continue on unedited). Here’s a link to the list of selectors and modifiers if you need it.
If I change namepass to namepass = ["sqlserver_requests"], it works with your example input above. Maybe it’s just a small naming thing.
