Configure TrackEvent in UI
It would be helpful to be able to configure one or more TrackEvent data sources in the Perfetto UI. Ideally the UI would have the option to query the current set of Producers to get a list of available processes, categories, and tags, and an easy way to filter accordingly.
Currently to use TrackEvent data sources, the trace must be executed outside of the UI in order to supply a handwritten TraceConfig.
@octaviantu is working on improving the recording page with some of these features (getting the list of producers + allowing that to be used to filter the recording UI) once that's done somebody else will have to pick up the UI work for the TrackEvent recording tab specifically.
@ddrone @betasheet @altimin Seems very in your wheel house :)
Agree, this should definitely be on our radar :) Technically, the querying described by @rickvanprim should be possible after @octaviantu's improvements. We can already query the track event data source descriptor with available categories from the service. We'd probably want to extend it such that it also specifies available tags.
Would be great having the ability to configure track events from the UI. Currently we are forced to write the config separately and invoke from the terminal.
@primiano maybe you can fix this as part of your look again into recording?
Folding this into https://github.com/google/perfetto/issues/2155 which is much nicer written version of this request.
