About Cisco Application Experience
Cisco Application Experience (AX) allows you to monitor the health of an application. Application health is measured using a score value, which is calculated based on the application's qualitative metrics—packet loss, network latency, and jitter.
AX is based on the Application Visibility records exported by routers, switches, and WLCs. Only application performance profiles that include application client-server stats, application response time and media type monitors are supported.
Based on the relevancy of an application, it is classified as Business Relevant, Business Irrelevant, or Default. This classification is done based on the NBAR standard. See "Business-Relevance Groups" in the Cisco Digital Network Architecture Center User Guide.
To view AX, you must enable Application Visibility on the Cisco network device. See Enable Application Visibility.
Cisco DNA Center supports configuring Application Visibility on routers, switches, and WLCs. You can view this identification in the Cisco DNA Center Inventory window under Device Role.
