Obi Ezechukwu — Mon, 30 Nov 2009 03:24:32 -0500

Functional requirements for mission critical applications often include software service level agreements (SLAs), which specify the maximum allowable latency for specific operations. Such requirements necessitate the monitoring of application performance, either at system testing stage or post deployment. This article will demonstrate how real-time performance tracing/monitoring can be achieved for spring applications using the functionality provided in Spring AOP and the Apache Log4j toolkit.

proceed(conn);
}
