The Datadog Fundamentals certification assesses the technical proficiency of DevOps engineers, system administrators, and cloud architects in implementing observability across distributed infrastructure. Candidates must demonstrate mastery in deploying the Datadog Agent, configuring host and container monitoring for AWS, Azure, and GCP environments, and executing synthetic testing procedures. The assessment requires expertise in constructing custom dashboards, implementing tag-based data aggregation, and configuring sophisticated monitor alerts using threshold and anomaly detection algorithms. Proficiency in utilizing Datadog APM for trace analysis, log management pipelines, and infrastructure health metrics is mandatory to optimize full-stack visibility within complex, cloud-native microservices architectures.
