Performance based alerts just got a lot more accurate.

Starting from November 30th, alerts will be based on all the 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)... 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 full list in Sentry.

Performing the review will require you to edit each rule marked with a "⚠" sign. You can then verify whether current thresholds are still valid or make adjustments as needed and save the changes to finish the review.

If you need any assistance, please reply to this email or contact support@sentry.io.
