Summary

This PR fixes the issue causing (mostly) login journey stuck for 14 min waiting for Telemetry call response.

I believe the issue was in how we handle the Observables for request events. I added extra comment in the particular code change.

I no longer can reproduce it, all the events are reported correctly:
image

Logs cleaning is to log in console only performance metrics event but not all EBT elements. Also not to report some browser errors that not Kibana specific.

Testing:

run the following script 3-4 times

PERFORMANCE_ENABLE_TELEMETRY=1 node scripts/run_performance.js --journey-path x-pack/performance/journeys/login.ts
  • script is completed without delays (e.g. doesn't hang on after hook in TEST phase)
  • telemetry requests are logged with correct counter and all finished, e.g. Waiting for telemetry request #2 to complete is followed by Telemetry request #2 complete
  • only events started with Report event "performance_metric" are in console output

I made a few changes to make it work correctly:

  • telemetryTrackerCount was always returning 1 since it was misplaced before observables.
  • delete requestFailure$ since we don't have to do anything in case of Telemetry request failure event. We fully rely on kibana service to make things the right way.
  • adding timeout of 60 sec to issue error notification in case of no new emitted events;
  • log messages on both complete & error
