Org stats for accepted message counts stopped showing up after 24.3.0 (self-hosted)

[caseyduquettesc]

Environment

self-hosted (https://develop.sentry.dev/self-hosted/)

Steps to Reproduce

Upgraded from 23.6.2 to 24.3.0 and everything seems to be working fine. Errors and transactions show up. Alerts fire. However, as an administrator, I've lost visibility into how many events are coming in to Sentry.

24.3.0 seems to only show the number of dropped events.

I found #55786, which gave me a pointer on where to look. I checked our outcomes table in clickhouse and it had no recent rows with outcome = 0, which I expect is the successful outcome. I checked when the last accepted outcome was and it came back as just before the upgrade.

SELECT *
FROM outcomes_hourly_dist
ORDER BY timestamp DESC
LIMIT 1000

Then I tailed the outcomes kafka topic and data was flowing in, but all the messages had a non-zero outcome.

bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic outcomes --offset 16204899386 --partition 0

Was there a change in Relay to stop emitting accepted outcomes? And if not, what conditions could cause Relay not to report accepted?

Expected Result

To see accepted and dropped counts in the org stats page.

Actual Result

Only see non-accepted counts

Relay only emits negative (non-accepted) outcomes, it can't emit accepted because there are more decisions taken later on the pipeline whether an event stays or is dropped. So what you're seeing is probably only Outcomes emitted from Relay (negative, like dropped events).

If I had to randomly guess one of your Sentry consumers isn't running.

Let's see if we can get this routed to someone who can help.

Figured it out. As accepted outcomes are now considered billing outcomes, they're published to outcomes-billing, but I had nothing consuming from that topic.

    def is_billing(self) -> bool:
        return self in (Outcome.ACCEPTED, Outcome.RATE_LIMITED)

The 24.3.0 release has no such consumer (https://github.com/getsentry/self-hosted/blob/24.3.0/docker-compose.yml), but I noticed one was added after the release in getsentry/self-hosted#2909

I started up the snuba-outcomes-billing-consumer and data started populating.

@caseyduquettesc thank you for figuring this out!
