Front-end monitoring is essential for ensuring the performance and availability of web applications. By monitoring key parameters, organizations can identify and resolve issues before they impact end-users.

Recommended Parameters

The following parameters are recommended for front-end monitoring:
Page load time: The time it takes for a page to finish loading in the browser.
First byte time: The time it takes for the browser to receive the first byte of data from the server.
Time to interactive: The time it takes for a page to become interactive for the user.
DOMContentLoaded: The time it takes for the initial HTML document to be parsed and the DOM to be constructed.
Load event: The time it takes for all of the page's resources to be loaded.
Network requests: The number of network requests made by the page.
Request size: The size of each network request.
Response size: The size of each network response.
HTTP status code: The HTTP status code returned by the server for each request.
Browser errors: The number of browser errors that occur on the page.
User experience metrics: Metrics that measure the quality of the user experience, such as bounce rate and conversion rate.

Monitoring Tools

There are a number of monitoring tools available that can be used to monitor front-end performance. These tools typically provide a dashboard that displays the values of the monitored parameters in real-time. Some popular monitoring tools include:
New Relic
AppDynamics
Dynatrace
Google Analytics
Pingdom

Best Practices

When monitoring front-end performance, it is important to follow best practices to ensure that the data is accurate and reliable. These best practices include:
Use a representative sample of users: The data collected should represent the experience of the majority of users.
Monitor from multiple locations: The data collected should be representative of the experience of users in different locations.
Use a variety of monitoring tools: Different monitoring tools use different methodologies, so using a variety of tools can help to provide a more complete picture of performance.
Set realistic goals: The performance goals that are set should be realistic and achievable.
Monitor regularly: Performance should be monitored regularly to identify trends and potential issues.

Conclusion

Front-end monitoring is essential for ensuring the performance and availability of web applications. By monitoring key parameters, organizations can identify and resolve issues before they impact end-users. By following best practices, organizations can ensure that the data collected is accurate and reliable, and can be used to improve the performance of their web applications.
