Which of the following is an example of a notification method supported by Dynatrace?

The correct choice, PagerDuty, is a widely recognized notification method integrated with Dynatrace for incident management and alerting. Dynatrace enables users to configure alerts that automatically trigger notifications to PagerDuty, facilitating timely responses to incidents that impact application performance or user experience. This integration allows organizations to effectively manage incidents by routing alerts to the right teams, ensuring that critical issues are addressed swiftly.

Using PagerDuty, teams can also customize on-call schedules and escalate alerts based on predefined criteria, enhancing their operational responsiveness. This aligns well with Dynatrace's capabilities in monitoring and observability, making the integration seamless for incident management workflows.

The other options listed do not represent officially supported notification methods within the Dynatrace ecosystem. While Facetime, Pusher, and WhatsApp are tools that can be used for communication, they do not have native integrations with Dynatrace for alert notifications, thus making them less relevant in the context of managing and responding to system alerts effectively.
