How to get events at Event Feed tab in Perfect UI?

[dinya]

Hello, team.

I started Prefect Server (v3.2.6) under Windows 10 (self-hosted with PREFECT_API_URL = "http://127.0.0.1:4200/api"):

$ prefect server start

and start tracking for events using:

$ prefect event stream

I try to emit custom event:

from prefect.events import emit_event
emit_event(event="test_event", resource={"prefect.resource.id": "tester"})

and see the event in the terminal with prefect event stream:

Subscribing to event stream...
{"occurred":"2025-02-20 12:41:12.099429+00:00","event":"test_event","resource":{"prefect.resource.id":"tester"},"related":[],"payload":{},"id":"cf91d3af-7b90-4684-a9db-85d5b714da32","follows":null}

But nothing happens in the Prefect UI at "Event Feed" tab and there are no records in the database tables event or event_resources.

Should I set any additional params/settings for the Project Server to see events in the Perfect UI (for automation)?

hi @dinya - this was a bug and the fix was just released in 3.2.7 - sorry about this!

tldr there was a recent change to background service discovery that resulted in:

• the EventsPersister not running by default
• events not being persisted
• events not being available in the Event Feed

Thanks! Now it works as expected :-)
