So if you're not running Loki, you're not going to be able to find traces using tempo? We use grafana and prom, but not loki.

Since Tempo is a k/v store that can retrieve traces given a traceID, we need either a metric system that can store traceIDs in exemplars OR any logging framework to log traceIDs that can be copied over to the Tempo Query UI.
