Question 8 of 73
A system administrator suspects that the slow performance of an application might be caused by lock contention.
To debug this further, what can the administrator do using IBM Support Assistant?
    Correct Answer: A
    The IBM Monitoring and Diagnostic Tools for Java - Health Center is a lightweight tool that monitors active IBM Virtual Machines for Java with minimal performance overhead. The Health Center suggests live tuning recommendations for Garbage Collection, profiles methods including call stacks, and highlights contended locks. This information can help you optimize performance, improve stability and optimize system resource usage.
    The tool is provided in two parts:
    ✑ An agent, which collects data from a running application. Java applications are monitored by the Health Center agent
    The Health Center client, an Eclipse-based GUI which connects to the agent. The client interprets the data that is obtained by the agent and provides
    Exam C9510-401: Question 8 - Image 1 recommendations to improve the performance of the monitored application. The client is available as an Eclipse plug-in and as part of IBM Support Assistant
    (ISA).
