Understanding Application Delivery Analysis

CA Application Delivery Analysis is the application performance management module of the CA Performance Center (CA PC) and the CA NetQoS Performance Center (CA NPC). CA Application Delivery Analysis tracks and measures end-user response time--without desktop or server agents. CA Application Delivery Analysis passively monitors IPv4-based TCP packets traversing the network between clients and servers, providing metrics such as network, server, and application latency for all mission critical applications.

When a TCP transaction flows across your infrastructure, it essentially flows through three main components of your infrastructure – the network, the server, and the application. When performance degrades on any of these components, it can adversely affect the transaction times to the end users.

CA Application Delivery Analysis measures TCP transaction time from the server switch, between each TCP client and the application port on a server. As shown in the example below, response times between the server switch and the client are network response times (indicated with a green arrow), and response times between the server switch and the server are server response times (indicated with a red arrow). The combined network and server response times (indicated with a yellow arrow) reflect the end-user’s experience with the application.

CA Application Delivery Analysis reports on the unique combination of time frame, application port, server, network, and performance metric. For example, you can report on the average Network Connection Time for all applications and servers that communicated with the Development I client network in the last 24 hours.

CA Application Delivery Analysis can be registered as a data source with the CA PC or the CA NPC when it is used with performance management. When CA Application Delivery Analysis is not used with performance management, it should be registered with the CA NPC. The CA PC or CA NPC security features--including users, roles, product privileges, and groups--let you control which users can view specific data in the management console.
