+This feature is available only if you're in the Early Adopter program. Features available to Early Adopters are still in-progress and may have bugs. We recognize the irony. If you're interested in being an Early Adopter, you can turn your organization's Early Adopter status on/off in General Settings. This will affect all users in your organization and can be turned back off just as easily.

+The **Alert Details** page shows you the number of times an issue alert rule was triggered over time, grouped in one hour buckets. Clicking on the alert rule name in the "Alert Rules" tab, or on the notification you receive will take you to this page. The page also includes the alert rule conditions, the current status of the alert (Warning, Critical, or Resolved), and alert details such as when it was created, when it was last modified, and the team that owns the alert.

 ## Metric Alerts
 
 Metric alerts tell you when a [metric](/product/performance/metrics/) crosses a threshold, such as a spike in the number of errors in a project, or a change in a performance metric, like [latency](/product/performance/metrics/#latency), [Apdex](/product/performance/metrics/#apdex), [failure rate](/product/performance/metrics/#failure-rate), or [throughput](/product/performance/metrics/#throughput-total-tpm-tps).
 
 Metric alerts monitor macro-level metrics for both error 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. When you create a metric alert, you can filter events by attributes and <PlatformLink to="/enriching-events/tags/">tags</PlatformLink>, which is particularly useful for aggregating across events that aren't grouped into single issues.
 
-These alerts use *Critical* and *Warning* triggers to measure severity. An alert’s current status is the highest severity trigger that is active, which can be one of three values: Warning, Critical, or Resolved. Sentry notifies you whenever an alert's status changes.

 When you create an alert, all the displayed alert types (except “Issues”) may be used to create a metric alert. You can create metric alerts for Errors, Sessions (Crash Rate Alerts), and Performance:
