For technical teams, a web application can be available from an infrastructure point of view and still deliver a poor experience to end users.
A login page may load slowly. A checkout step may fail intermittently. A business-critical journey may remain technically “up” while becoming frustrating in practice for users. This is exactly the kind of gap Centreon DEM is designed to address.
Formerly known as Quanta, Centreon DEM extends observability to the digital experience itself. Its goal is not only to tell you whether a web application is reachable, but also to help you understand how it behaves for users, how it performs over time, and where improvements are needed.
A broader view of web application performance
Centreon DEM combines several complementary approaches.
The first one is Synthetic Transaction Monitoring, also called user journeys. These are automated scenarios executed in real browsers at a defined frequency. They can simulate key actions such as loading a page, logging in, navigating to a specific section, or completing a business action. This makes it possible to verify not just that a page responds, but that a complete journey remains available and stable over time.
The second one is Real User Monitoring. Instead of relying only on simulated checks, Centreon DEM can also collect technical performance data from actual user visits. This provides a more realistic view of what users experience across browsers, devices, countries, cities, and individual pages.
Taken together, these two approaches give teams both a controlled and a real-world perspective on digital performance.
From availability to actual user experience
One of the strengths of Centreon DEM is that it moves the discussion beyond basic uptime.
With synthetic journeys, availability is measured at the level of a real interaction path. That means the question is no longer only “Is the homepage up?” but rather “Can a user actually complete the expected action under good conditions?”
This is especially useful for teams that need to monitor login flows, customer portals, internal web tools, or transactional applications where a service can appear healthy while still failing at a critical step.
Performance analysis that goes deeper
Centreon DEM also helps investigate performance issues in detail.
The platform provides performance scores built from multiple indicators, including Core Web Vitals, and builds optimization recommendations that help teams understand what is slowing pages down. Blocking resources, rendering delays, heavy assets, and technical bottlenecks can all be identified more clearly.
This makes Centreon DEM useful not only for operations teams, but also for web teams, developers, and anyone involved in improving site performance and user satisfaction.
Real user visibility across pages, devices and geographies
With Real User Monitoring, teams can explore how performance differs depending on the page being viewed, the browser being used, the device type, or the user’s location.
This is valuable because the same application can behave very differently depending on the actual context of use. A page that performs well on one browser or network may degrade significantly in another situation. Centreon DEM helps surface these differences and identify where the largest impact on users really is.
A technical bridge back to infrastructure
Another interesting aspect of Centreon DEM is its ability to connect digital experience with more technical signals.
In addition to front-end monitoring, the platform can also expose system-level information such as CPU, memory, storage, or service-specific indicators. This helps teams correlate degraded user experience with underlying infrastructure behavior and better understand where issues come from.
For Centreon Infra Monitoring users, this makes DEM particularly relevant and complementary.
A digital sobriety dimension
Centreon DEM also introduces an increasingly relevant perspective regarding CSR goals : digital sobriety.
Alongside performance indicators, the platform can help assess the environmental footprint of a page load and provide visibility into the efficiency of a site from a sustainability standpoint. For teams that want to combine performance optimization with more responsible digital practices, this is a decisive additional layer of value.
Want to see it in action?
If you would like a more concrete walkthrough of the solution, a product tour is available and shows how Centreon DEM approaches synthetic monitoring, real user monitoring, performance analysis, and system data from within the interface.
And if you want to explore the platform more directly, a 30-day free trial of the SaaS version is also available.
These two resources are a good way to better understand how Centreon DEM can complement infrastructure monitoring with a more user-centric view of web application performance.
