Gartner defines digital experience monitoring (DEM) tools as those that measure the availability, performance and quality of the user experience (human user or digital agent) of critical applications. This can include internal users (employees and contractors), external users (customers and partners) or a digital agent connecting to an API. In addition to performance, DEM technologies enable observability of user behavior and journey based on their interaction with applications.
Infrastructure monitoring tools capture the health and resource utilization of IT infrastructure components, no matter where they reside (e.g., in a data center, at the edge, infrastructure as a service [IaaS] or platform as a service [PaaS] in the cloud). This enables I&O leaders to monitor and collate the availability and resource utilization data of physical and virtual entities — including servers, containers, network devices, database instances, hypervisors and storage. These tools collect data in real time and perform historical data analysis or trending of the elements they monitor.
