Datadog APM
Datadog APM (Application Performance Monitoring) is a distributed tracing and performance monitoring tool that helps developers track requests across microservices and applications in real-time. It provides detailed insights into latency, errors, and dependencies to identify bottlenecks and optimize performance. The tool integrates with Datadog's broader observability platform, allowing correlation with metrics, logs, and other telemetry data.
Developers should use Datadog APM when building or maintaining complex, distributed systems, especially microservices architectures, to monitor application health and troubleshoot performance issues efficiently. It is valuable for teams needing to reduce mean time to resolution (MTTR) by pinpointing slow database queries, external API calls, or service dependencies in production environments. Use cases include e-commerce platforms, SaaS applications, and any system where uptime and user experience are critical.
