Last9 Real User Monitoring observes performance, errors, and network behavior from people using web and mobile applications, then connects frontend problems with backend traces. Its SDKs cover Web, Android, iOS, React Native, and Flutter. Web monitoring includes Core Web Vitals such as LCP, FCP, CLS, INP, and TTFB, along with JavaScript errors, rejected promises, fetch and XHR activity, and single-page application route changes. Mobile telemetry includes launch and screen timings, crashes, and DNS, TCP, TLS, and TTFB network phases; Android monitoring also detects ANRs. Each SDK adds W3C trace context through a traceparent header so requests and backend work can share a distributed trace. The service collects diagnostic telemetry without recording rendered DOM, screen video, or visual session replay. Sampling is configurable per session from 0 to 100 percent. Alerts can cover error rate, p95 latency, crashes, and ANRs. Last9 lists more than 100 integrations, emits spans and logs over OTLP, and advertises encryption, SSO, MFA requirements, role-based access, audit trails, zero-trust architecture, and 24x7 support.
