Alerts & Notifications

Alerts notify you about errors and performance problems in your application. Notifications send emails for situations like an issue state change or if a release has deployed. Alerts are customizable to your organization's needs with options to pair with integrations, flexible configurations, and choices for both error or performance alerting.

Issue Alerts for Errors

Issue alerting sets alerts on issues. Issues are grouped automatically by Sentry based on stack trace and other factors. Create alerts for issue-level changes, such as:

  • New issues
  • Issue frequency increasing
  • Resolved and ignored issues getting unresolved

Metric Alerts for Errors & Performance

Metric alerts monitor macro-level metrics for both error events and transaction events. A metric takes a set of events and computes an aggregate value using a function such as count() or avg() applied to the event properties over a period of time. Metric alerting is triggered when a threshold is breached.

You can filter events by attributes and tags, which is particularly useful for aggregating across events that aren't grouped into single issues. Use metric alerts for alerting on:

  • New issues
  • Total errors in your project
  • Latency: min, max, average, percentile
  • Failure rate
  • Custom metrics


Notifications are emails triggered by changes in issue state, releases, and quota usage. To change the frequency of your email notifications, configure your personal Notification Settings.

Types of Sentry notifications:

  • Workflow notifications: Activity involving user actions and state changes on issues. Includes activities such as resolution, assignment, comments, and regressions.

  • Deploy notifications: When a release is deployed, Sentry automatically sends an email to users who have committed to the release.

  • Quota & Usage notifications: Emails about approaching quotas, exceeded quotas, and spike protection.
