Hello! I copy/pasted the example clickhouse query. Nothing returns, is this expected? Query from <https://signoz.io/docs/tutorial/writing-clickhouse-queries-in-dashboard/#groupby-a-tagattribute-in-distributed-tracing-data|here>.

where can I see the tables / attributes signoz stores so I can build my queries?

And, is it saving the already filtered data of traces dashboard in the roadmap? I already have a nice builder filtering what I care about, but now I have to build the query to show the same I already did in the UI :sweat_smile: :face_with_spiral_eyes:

Yes

It’s possible that `peer.service` attribute is not set in any of your service. In that case it’s expected that there’s no data.
Maybe try `http.method` if your services use REST apis.
