Datadog has introduced the Host Info feature in its Application Performance Monitoring (APM) platform, which provides immediate infrastructure-level context for service requests by displaying host system metrics and tags side-by-side with request traces. This new feature brings APM and infrastructure monitoring closer together, offering full-stack observability without the need to switch tools. The Host Info panel displays host system metrics and request traces on a single pane of glass, allowing users to easily correlate slow requests with system issues, such as overloaded database servers. By showing host data inline with request traces, users can reduce time spent searching for the root cause of an issue and gain increased visibility into their full system.
