Watchdog is Datadog's AI-driven engine that automatically detects performance issues in infrastructure and applications using algorithms like anomaly detection. A new feature, Impact Analysis, assesses the impact of these issues on end users by analyzing metrics from RUM SDKs. It helps prioritize troubleshooting by highlighting which performance anomalies affect the most users, thereby reducing business impact and aiding in the prevention of future issues. Impact Analysis provides detailed information on user impact, including which users were affected, and facilitates the creation of postmortems by exporting data to Datadog Notebooks. This feature is automatically available to all Datadog APM and RUM users, enhancing visibility into service performance and streamlining incident response.
