Performance based alerts just got a lot more accurate.

Starting from November 30th, alerts will be based on all the transaction events you send to Sentry, not just the ones that are stored.

How does this affect me, and my team?

Because we're potentially extracting metrics from a significantly larger number of events, existing thresholds could result in a spammy experience. Instead of waiting until November 30th, we recommend that you take action now by reviewing the thresholds of each affected alert. This will allow you to migrate alerts ahead of time with the assurance that they will work as expected.

How do I review my thresholds?

It's pretty simple really, but unfortunately, also pretty tedious (sorry about that)...

We’ve marked all your affected alerts with a "⚠" sign, so that you can quickly identify the ones that need your attention. In order to perform the review:

To get the ball rolling, we've included a shortlist of alerts that need review below, but click on "View Performance Alerts" to see the list of affected ones in Sentry.
