CloudMonitor:Frontend applications

Last Updated:Sep 28, 2025

CloudMonitor 2.0 monitors frontend application performance with a focus on the user experience. It reproduces the complete user journey and tracks page load speed, API service invocations, and stability. Stability monitoring includes JavaScript (JS) errors, network errors, crashes, and Application Not Responding (ANR) errors. The service also supports log data queries to help you quickly trace and locate the cause of faults and improve the user experience.

Multi-platform support

CloudMonitor supports application monitoring across multiple platforms, including browser applications, mobile applications, and miniapps. The integration process is simple and flexible, allowing you to collect application experience data without manual instrumentation.

Quick integration

The integration process is simple and flexible. You can import the dependency package into your frontend application project and configure a short initialization code snippet. This lets you collect client-side application performance data without any additional instrumentation.

Full-link monitoring

This feature uses user sessions as the starting point for experience analysis and tracks errors, slowdowns, and abnormal issues that occur during user interactions. The integration of network analysis with server-side application monitoring provides end-to-end analysis. This helps you create a complete path for troubleshooting.

Log query

Frontend application data is stored in your Simple Log Service (SLS) instance. You can use SLS to query and use this log data. Browser Monitoring also supports integration with the Prometheus service, which lets you use Prometheus to manage Browser Monitoring metrics.

Data exploration

The data exploration feature in Browser Monitoring supports flexible analysis for troubleshooting. You can perform a combined analysis of all available dimensions and metrics and configure filters to view data for any combination of them. This helps you shorten the troubleshooting path and quickly identify the scope of a fault.

Visualization

In addition to the standard console pages for analysis, Browser Monitoring provides pre-configured, out-of-the-box dashboards. These dashboards are built on the powerful visualization capabilities of ARMS Grafana and are designed for specific scenarios. You can also use ARMS Grafana to create custom dashboards that meet your specific business needs.
