Gartner’s view is focused on transformational technologies or approaches delivering on the future needs of end users. It is not focused on the market as it is today.
Gartner defines the application performance monitoring (APM) and observability market as software that enables the observation and analysis of application health, performance and user experience. The targeted roles are IT operations, site reliability engineers, cloud and platform teams, application developers, and product owners. These solutions may be offered for self-hosted deployment, as a vendor-managed hosted environment, or via SaaS.
