## Frequently asked about Real User Monitoring
### What is Datadog Real User Monitoring?
User Monitoring (RUM) gives you full visibility into every user session on your web and mobile applications. It helps teams detect, investigate, and resolve frontend errors, crashes, and performance issues by correlating real user behavior with backend traces, logs, and infrastructure metrics.
### Does RUM cover both web and mobile applications?
Yes. One RUM product covers browser applications, native and cross-platform mobile apps, desktop, and connected devices, with consistent metrics and a single troubleshooting workflow across both.
### Which platforms and SDKs does RUM support?
Datadog RUM supports browser applications, the Android ecosystem (including Android TV and Android Automotive OS), Apple platforms (including iOS, iPadOS, tvOS, watchOS, and visionOS), Roku, Electron, and C++. On mobile, Datadog RUM also comes with SDKs for cross platform frameworks: React Native, Flutter, Kotlin Multiplatform, Unity, and .NET MAUI. The browser SDK adds dedicated plugins for React, Angular, Vue, Next.js, Nuxt, Salesforce, and Shopify.
### What is a session?
A session is a continuous navigation on your web or mobile application, and it is the unit RUM meters and bills on. It can last up to 4 hours of continuous activity, and expires after 15 minutes of inactivity. Each session groups together every view, action, resource, error, and other events a user generates. When a mobile app contains webviews and both the web and mobile applications are instrumented, Datadog bridges them into one mobile session, and only that session is billable.
### What data does RUM collect?
RUM collects by default the views, actions, resources, errors, and long tasks, along with context like app version, device, operating system, browser, and geography. You can enrich sessions with additional events and any custom attributes. Inputs are masked by default in Session Replay, and you can apply finer masking rules to control exactly what gets recorded.
### How does RUM connect to my backend?
RUM links outgoing network requests from your application to the backend APM traces and logs generated by the same requests, so you can move from a frustrated user to the responsible service in one click. RUM is a standalone product and does not require APM or Log Management, but connecting them is what helps you seamlessly troubleshoot across the stack.
### What is the difference between Measure and Investigate?
RUM Measure applies to every session you collect. It powers 30+ metrics you can use in dashboards, monitors, and SLOs. Metrics are computed on 100% of your traffic and retained for 15 months. RUM Investigate applies only to the sessions your retention filters keep, and it gives you full session detail, error and crash tracking, profiling, and one click correlation to backend traces and logs.
### How does RUM pricing work?
RUM is billed per 1,000 sessions per month, split into two parts. RUM Measure covers your full session traffic at $0.15 per 1,000 sessions, and RUM Investigate covers the filtered sessions you retain in full detail at $3 per 1,000 sessions. Annual, month to month, and on demand rates are available, and add-ons like Session Replay are priced separately per 1,000 sessions.
### What is Session Replay?
Session Replay is a RUM add-on that records and replays any web or mobile session, so you can watch exactly what a user did before hitting an error. It shares RUM's data model, and inputs are masked by default to protect sensitive data.
### How do I get started with RUM?
You can start with a 14-day free trial of the entire Datadog platform. Instrumenting an application is as simple as importing the package and initializing the SDK. Most teams are collecting sessions within minutes, and you can create retention filters and monitors from the UI without redeploying.
