PagerDuty introduces Workflow Extensions, allowing customers to configure custom workflows with add-ons like Datadog dashboards and graphs for dynamic incident response. Embedded Datadog dashboards provide real-time alert context, while inline metric graphs offer detailed information on metrics that triggered the alert. These features can be accessed through PagerDuty's mobile interface for convenient alert investigation on the go. By integrating these tools, users can experience improved incident handling and faster recovery times.
