Spike detection

Learn how Bugsnag's error spike detection works.

Bugsnag email and team notification integrations can be configured to alert you when the error rate on your project increases significantly. The spike detection is particularly useful in highlighting critical issues in your app - for example a loss of connectivity to a database or a bad deploy.

How it works

Bugsnag is constantly monitoring the rate of errors in each of your projects. The notification will be triggered when there is a significant increase in error rates that is sustained for at least 5 minutes.

What isn’t detected

A significant increase in occurrences of one error won’t necessarily trigger a notification, especially if there is a high background level of errors in your project.

Additionally very brief spikes lasting less than five minutes won’t trigger a notification.

The release stage and severity filters do not apply to spike detection.
