What is Real User Monitoring?

Real User Monitoring (or RUM) consists in measuring your site from your customers' browsers as they visit the site.

Unlike synthetic measurements, which consist in observing the performance of your site from a fixed point, feedback measurements are highly dependent on many external factors, such as the bandwidth of the visitor to your site or the performance of his browser. Nevertheless, "Real User" measures make it possible to observe a much wider range of pages, browsers, platforms, etc

The RUM will therefore allow you to observe the performance felt by your visitors!

How to activate it?

The RUM is available as an option for all licenses. We invite you to contact our sales department for any questions.

Once the RUM is activated for your license, you will find a "Real User Monitoring" section in the "Integrations" page of your site's Quanta settings. This will allow you to retrieve a tag, in the form of a piece of Javascript code, that you will need to integrate into your site or your Tag manager. You can contact your branch or our support for more information on how to proceed.


Exactly how does it look like ?

Once the RUM is installed on your site, you will start to see graphics in the "Real User Monitoring" section of the application.

The screen is divided into 3 sections:

  • An "Overview" section, allowing you to use generic KPIs.
  • A "TOPS" section allowing you to view the main metrics on different segments (by Browser, OS, City, Country and URL).
  • A section containing the graphs corresponding to the general metrics.

If the overview and graphs will allow you to quickly get relevant information on the performance felt by your users overall, you will most likely want to be able to compare different segments, that's what the Tops will help you with.

Each Top presents you with the most popular user segments (in terms of page views) on several "perspectives", this will allow you to quickly identify those for whom optimization would have the most impact.

By clicking on one of the Top values or on the small magnifying glass when you hover over the panel, you will arrive at a page with detailed graphs allowing you to compare different segments. This will allow you to answer questions such as:

  • Are users using Chrome globally faster than those using Firefox?
  • What is the average Speed Index of users under Android?
  • Which of my URLs had different loading times during the last production run?

From this page, select the values to compare and then click on "Compare" to have comparative graphs. You can also click on one of the values directly to view the metrics of that value.

The pagination and search, visible when you hover over the panel, will allow you to select the values that interest you most.


I still have some questions

Will the tag have a negative impact on my visitors ?

The Quanta tag does everything possible to minimize the impact on user performance:

  • The few lines of Javascript that you put at the top of your page will actually load a larger file that will take the measurements. This file is loaded asynchronously, so browsers will not load it first and its loading will not block the loading of other critical resources.

  • The measured data are relatively inexpensive to observe, in order to limit the impact on performance.

  • We try to keep the tag as light as possible, in order to limit the bandwidth consumption of your users.

  • Measurements are sent after the page load is completed, so that resources are not used during the loading of critical elements.

  • Finally, in the event of a possible unavailability of Quanta, the sending of the data will fail but will not impact the loading of your pages.

Is it compliant with the new data protection laws ?

We do not store any personal data such as IP addresses or cookies. The data we store is aggregated by segment and therefore anonymous.

The tag deposits cookies for its internal use (for example to detect if it is a new session)
