Detecting application performance issues that require mitigation

An HTTP application service's performance issues might be caused by changes in a pool member's status. Issues with a pool member can lead to increases in application response time, server-side round trip time (RTT), incomplete transactions, and server errors. An application that sustains these increases can result in a critical or moderate health status. You can use application alerts to isolate managed objects, such as pool members, or virtual servers that reported issues. You can use your findings to adjust your application's managed objects (LTM pool members) in order to improve performance.

You identify an application with changes in pool member status by using the application health status screen (

). Once an application and application service (either HTTP or TCP) is identified, you can further evaluate which pool member(s) is affecting performance.
