This feature brings vital insight into the health of your applications so you can deliver the software experiences your customers deserve.

Here’s a look at some of the best ways to use the Response Codes tab as a measure of application health.

Provide visibility into user experience

XHR/AJAX calls are made to transfer data from the server to the browser when loading or updating a webpage. If you have a failing or poor performing XHR call, that could mean parts of your application are not behaving as intended, leading to a poor user experience with your application.

Monitoring the response codes of XHR calls is an important factor in maintaining a finger on the pulse of your application health. If you see an uptick in bad response codes, you’ll know you need to investigate.

Ensure your single page application experience is flawless

XHR/AJAX calls are heavily utilized in loading the additional page information required for virtual pages in a single page application (SPA). This is why poor performing or failing XHR calls are particularly detrimental to the user experience.

Therefore, it’s especially important when building a SPA to monitor your network responses to spot any uptick in bad network response codes quickly. For example, if you see the number of 500 responses increase, you’ll know there has been a server error that you may need to investigate.

The percentage of 2XX response codes is an important measure of the health of your application. Maintaining a finger on the pulse of this measure helps ensure your application is performing as intended, and you’re delivering a flawless user experience for your customers.
