How to Use the Real User JS and General Errors + CSP Violations Page

Summary:

The Real User JS & General Errors + CSP Violations page allows you to see what kind of errors are happening on your site, where they're coming from, and who's impacted by them. In this article, we'll walk you through the page by each section:

• JavaScript Errors by Type
• Middle Section (top locations, domains, etc.)
• JavaScript Errors Over Time
• Errors Table
• JavaScript Error Drill-down
  • JavaScript Errors Over Time
  • Pages With JavaScript Errors

Note: All filter options apply here, just like all other pages in Real User Data. All the filter options can be found in the top right corner drop down menu.

JavaScript Errors by Type

The left side (All JavaScript Errors) shows the total number of observed errors. The right side (Unique JavaScript Errors) shows the number of those errors that were unique, meaning these errors are not appearing multiple times.

Middle Section (top locations, domains, etc.)

This section shows all the top Locations, Domains, Pages, Devices, OS, and Browsers that are having errors. This section allows you to see at a glance where where the problem areas are.

JavaScript Errors Over Time

In this graph you can see what kinds of errors are happening over time and when they are happening in a simple view. For example, when you see spikes in this graph, that is something that might need to be investigated.

Errors Table

This table breaks down each error and shows you all the details such as: error type (CSP violation, XHRError, TypeError, etc.), file name, error message, number of errors, percentage of total errors, and session impacted (how many users experienced the error).

*If you want more information on a specific error, you can click the row and it will bring you to a drill down page.

*JavaScript Error Drill-Down

The drill-down section here is a new page which has nearly all of the data from the original page, but this is for the specific error you clicked on. Of course the error message is displayed above, the file name and contextual details are to the left, and to the right and below are the top locations, pages, domains, etc. that this error is happening on.

JavaScript Errors Over Time

This graph shows how many times we have seen this specific error over time. By changing the time period you can see if there are any trends in the data, or when this error is happening most often during the day.  

Pages with JavaScript Errors

This scatter plot graph shows the individual errors detected from the above line graph. You also get the same in a table below. 

Here, once again you’ll be able to click on the error and will bring up a drill down section below. Some of the columns include: Referrer, Traffic Segments, Number of Errors, Page Speed, and more.
