Indication that span limits were reached in Trace View

Grafana Tempo
1

Opentelemetry supports span limits which make sure that spans do not grow indefinitely, e.g. by limitting the number of events that are recorded. However, a counter is present to indicate that some events have been dropped and are not present on the span.

I was unable to find this in the Grafana UI. I tried getting the raw trace from Tempo API and there is a field droppedEventsCount on each span.

Am I overlooking something or is this information not present?

Hey @mladedav, I created this issue to track this request.

Thanks. I wanted to create an issue today but I was unsure if it was a UX issue, grafana/ui package issue or even a chore so I didn’t in the end.
