Gartner defines digital experience monitoring (DEM) as the measurement of the availability, performance and quality of the user experience of applications. This can include internal users (employees), external users (customers and partners) or a digital agent connecting to an API. In addition to performance, DEM enables observability of user behavior and journeys based on their interaction with applications. DEM tools allow I&O leaders to understand the availability, performance and reliability of business applications, networks and infrastructure by focusing on understanding the user experience. This is in contrast to other performance monitoring approaches, such as observability platforms, that understand the inner workings of 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.
