Show some tags on closed summary line

[ringerc]

Often the summary line of a closed span is completely uninformative.

It'd be very useful to show a (possibly abbreviated) tag and value "in line" on closed spans, between the span name and timeline. For example, for SQL query related spans, the start of the query text.

It's probably practical to just let trace providers add an extra tag like "jaeger.summary" that shows whatever they want the viewer to see. That way there's no UI configuration etc.

(Enhancement request, obviously. Can't implement right now, have my hands full trying to bring the C++ client up a bit).

Thanks for the suggestion! Interesting idea.

@yurishkuro Just wanted to call this out.

Open to suggestions, but "between the span name and timeline" doesn't really work unless we actually add an extra column that can be shown/hidden. I think we discussed elsewhere the ability to show various other columns in front of the timeline.

Yep. Something like that is what I was thinking. Sorry if it's been previously discussed, I didn't find anything of interest in a search. In many cases this info would be much more useful than a service name. Especially when your traces are entirely or predominantly from one service.
