Java Profiling for Disk Usage

Question

I want to currently profile my application which uses JCS for caching.I have used the default profiler which comes with netbeans IDE and it proves satisfactory for memory.But I want to profile my application for disk usage,because my app caches items in disk I want to verify its performance.Is there a way to do this using the profiler that comes with netbeans or using any commercial profiler such as JProfiler. Thanks in advance

Answer 1

JProfiler has a file probe that will show you:

• a time line of files and the I/O activities on them
• a list of all files with their I/O statistics
• "hot spots", i.e. files on which most read/write operations are performed together with cumulated back traces to your code
• telemetries for total read and write throughput
• an "events" view showing single I/O operations

You can do this using one of the built-in probes in JProfiler.
