IBM Health Center for Java is a low overhead agent included with the WebSphere Application Server Java SDK that collects Java configuration and performance data. The data collected includes CPU, native memory, method profiling, garbage collection, locks, threads and others. Configured in headless mode, the agent continuously collects performance data into Health Center files (.hcd). This data is valuable not only for performance tuning, but also serves as a performance "flight recorder" for root cause analysis of production incidents. The WebSphere Commerce Health Center Report tool uses the Health Center file (.hcd) to generate a web-based report of the performance data with WebSphere Commerce specific insight.
Tip In case of errors, validate the Health Center file (.hcd) by opening it with the Health Center Eclipse client and review its contents.
