摘要
To increase visibility into an application's performance, an application performance management system monitors transactions of an application at runtime to identify components or methods which significantly contribute to the execution of the transaction but are not instrumented. Since these methods are uninstrumented, the application performance management system has no visibility into and does not receive performance metrics for the methods. Identified components which contribute to the transaction are instrumented to decrease the visibility gap and provide additional performance information about the transaction of the application. During visibility gap detection, the agent analyzes runtimes of instrumented components to identify a component with a largest attributable runtime. The component is analyzed to identify uninstrumented, children components which it invokes. One or more of these children components may be instrumented and reloaded into an application to provide performance information during a subsequent execution of the component.
