App metrics


I am interested in using the “app metrics” feature, but not sure what to do after enabling the feature flag.

Any tips on using it?

We apologize for the confusion with this feature flag visibility, but the app metrics are not currently available.

Thanks Jaimie!

Relevant for some use cases: Since runtime version 4.85.0 journey.profiling can be enabled for an app which makes performance profiling in Chrome a lot simpler for developers. This includes:

  • Logging all queries and view functions together with their duration.
  • Adding info on the sync system overhead and digest cycles.
  • Adding info on index usage which makes it easier to see which queries can be optimized, versus running explain() individually on queries.
  • Making it possible to enable this profiling in production environments, not just testing.
