App Analytics is a new tool that provides a detailed view into application performance by capturing the level of detail across hundreds or thousands of services. It enables users to explore and analyze all their spans in one place, filter down to find specific traces using high-cardinality dimensions such as customer ID or user ID, and visualize data using high-cardinality attributes. App Analytics unifies the three pillars of observability—metrics, traces, and logs—with tags at its center, allowing users to pivot between related data sources using common tags. It provides real-time analytics views for on-the-fly troubleshooting and spot-checking, as well as the ability to add these views to dashboards for continuous monitoring. By integrating with Datadog APM, App Analytics gives users unparalleled visibility into their applications and how their customers interact with them.
