Real user session visibility
Understand how real users navigate, interact, and experience your Angular application under live traffic. Track full user sessions to identify friction points that backend monitoring cannot reveal.
Angular Error and Performance Monitoring
Get complete visibility into your Angular errors and performance issues that are impacting your end user experience. Fix critical issues sooner with in depth data points that helps you in analyzing and resolving issues with great speed.
Challenges
Get deep visibility into how real users experience your Angular app
Angular route performance insights
Monitor Angular Router navigation and virtual page loads to see which routes are slow and why. Identify delays caused by JavaScript execution, API calls, or heavy component rendering.
Frontend performance metrics
Measure real-world frontend performance including load time, interaction latency, and Core Web Vitals (LCP, CLS, INP). See how Angular performance varies across devices, browsers, and networks.
Runtime JavaScript & Angular errors
Capture runtime JavaScript errors and Angular-specific failures that don’t crash the app but break user experience. View stack traces with route, browser, and release context.
User interaction issues
Detect slow or broken user interactions such as repeated clicks, unresponsive buttons, and stalled flows. Identify UX issues caused by frontend logic rather than backend failures.
Session-to-code correlation
Connect user sessions directly to frontend errors, slow routes, and backend APIs. Quickly trace issues from real user impact to the exact Angular code path responsible.
Browser & device-level insights
Analyze Angular performance across different browsers, devices, and operating systems. Identify environment-specific issues that affect only certain user segments.
Faster frontend debugging
Use real user context to prioritize and fix Angular issues faster. Reduce time spent guessing by focusing on problems that impact real users the most.
Change Detection Execution
- Measure change detection cycle frequency at component level during real user interaction and correlate execution cost with DOM update latency.
- Identify template bindings, @Input propagation, and event handlers that trigger repeated view checks without actual state changes.
- Analyze lifecycle hook execution timing during initialization and update phases to isolate rendering delay contributors.
- Detect propagation of state updates across component hierarchies that causes redundant change detection passes and UI instability.
Zone-Based Asynchronous Execution
- Track asynchronous task execution within Angular Zone context and measure delay between task scheduling and UI rendering.
- Analyze microtask and macrotask queue behavior during API calls, timers, and user-triggered workflows.
- Identify concurrent async execution paths that block rendering and delay interaction readiness.
- Correlate asynchronous execution timing with navigation latency and screen stability issues.
Router and Lazy Module Execution
- Break down route transition timing across guards, resolvers, lazy module loading, and component bootstrap execution.
- Identify blocking operations during route initialization that delay first render and user interaction.
- Measure lazy-loaded module download and initialization latency across devices and network conditions.
- Correlate navigation execution timing with workflow interruptions and interaction delays.
RxJS Stream and Subscription Execution
- Measure latency between Observable emission, operator execution, and DOM rendering during real user sessions.
- Identify RxJS operator chains that introduce processing overhead in navigation, search, and dynamic UI updates.
- Detect persistent subscriptions that continue triggering component updates after state stabilization.
- Analyze concurrent stream execution and its impact on rendering performance and interaction responsiveness.

Angular performance monitoring collects in-depth metrics on each user-interaction and analyzes everything from page load events to HTTP requests to front-end application crashes.
Monitoring Angular apps helps you to pinpoint Angular issues, measure user experience with the key metrics provided and fix them as soon as possible.
In real-time monitoring, a small piece of code is injected into the application to collect metrics while it is in use.
The browser-based applications can be monitored by injecting a JavaScript code which tracks and detects the front-end performance issues along with the XHR requests.
It also provides you with in-depth front-end metrics which helps you in resolving the issues at a faster rate.
Atatus Real User Monitoring supports front-end frameworks such as JavaScript, AngularJS, Angular, React, Backbone, Ember, Vue, Ionic, Ionic2+ and Meteor.
Also, you can embed the JavaScript snippet in a web page inside the tag and monitor.
Yes, we collect the IP address of the browser client used by the user, which will be displayed in the users' information along with the page views, load time, error count and last seen of the user, respectively.
Yes, we do collect core web vitals metrics such as:
- First Contentful Paint (FCP)
- Last Contentful Paint (LCP)
- First Input Delay (FID)
- Cumulative Layout Shift (CLS)
- Time To First Byte (TTFB)
As part of Atatus Browser Monitoring, we have a Single Page Application (SPA) Monitoring feature that gives a 360-degree view of what customers are doing with single-page apps and AJAX-based apps.
The benefits of real-time monitoring of users are substantial.
- It provides actual end-user experiences
- Easily track high value pages
- RUM metrics can determine whether service level agreements (SLAs) are being met, and to determine how users interact with an application and how developers can simplify the user interface.
Compared to all other browser monitoring tools Atatus offers affordable pricing plans. Collaboration requires in any monitoring tool so we do not limit your capabilities by charging per user.
We collect all the data points including Spans and Traces that are necessary for you without the need for you to select which to retain. With this you can easily monitor your entire application.
Rather than stop collecting the front-end performance metrics, our sales team will contact you to discuss the requirements.
Start free and send your first trace with OpenTelemetry or the Atatus agents. APM, logs, RUM, infrastructure and SIEM, all on one timeline.
