How to create summary of traces without needing to open subspans?

Grafana Tempo

So, I am exploring OpenTelemetry in combination with Grafana Tempo cloud.

I got my spans uploaded, and in Grafana cloud I see a nice overview of the traces.

Now I am looking to actually make this data useful. So I was expecting to easily list all the main traces with a few span attribute columns in a nice overview.
However, I am not able to do that.

The only thing I can get is a table with some predefined trace fields, and then expandable sub spans that show the fields I need. I don’t want to expand traces, I just want a simple list with extra fields I am interested in.

So what I am looking for is:

trace id | start time | service | name | duration | span custom field | span custom field |

However, I get:

trace id | start time | service | name | duration | 
>  span id | start time | service | name | duration |  span custom field | span custom field

My TraceQL query is:

{resource.service.name="service" && span.foo != nil && span.bar != nil} | select ( span.foo , span.bar)

And I use a Table in Grafana.

Am I crazy? Why can’t I just get a list of stuff I want? I don’t care about the subspans, I only care about the whole trace, and some subspan attributes.

Is this possible at all?

Also, I cant seem to rename the custom span titles from foo to Human Readable in Grafana or TraceQL?

Ah, I got a little further now. In Options in the query there is a selector for Table format which can change to Spans.

So, I got a lot further, but when switching to Spans, the displayed duration is from the span, not from the trace…

So how can I show span attributes from subspans while also displaying total trace duration? (Summarize the trace basically)
