Datadog has introduced a new feature called tiered alerts, which allows users to configure different severity levels for their metric alerts. This feature enables the user to trigger alerts that go to different people or via different channels depending on the alert severity. With this feature, users can set up alerts to send email or chat notifications for relatively low-urgency issues and page the engineer on call if the situation gets worse. The new feature works with any integration that supports regular metric alerts and reduces alert fatigue by ensuring that the right people receive the right alerts over the right channels. Users can try out this feature by navigating to the monitors page, choosing Metric as the monitor type, defining threshold values, and configuring notification settings.
