A session is a user journey on your web or mobile application. A session usually includes multiple page views with their associated telemetry.
A session expires after 15 minutes of inactivity, and its duration is limited to 4 hours. After 4 hours, a new session is automatically created.
Datadog collects all the pages visited by your end users along with the telemetry that matters: resources loading (XHRs, images, CSS files, JS scripts, etc), frontend errors, crash reports, and long tasks. All of this is included in the user session. Datadog charges per ten thousand (10,000) sessions ingested in the Datadog Real User Monitoring (RUM) service.
Yes, without any configuration on your side. Datadog RUM automatically tracks page changes.
With the out-of-the-box APM integration, you can tie any XHR/Fetch request to its corresponding backend trace.
Browser logs are automatically tied to the corresponding RUM session, enabling you to monitor when they happen during the end user journey.
