How can I get system/hardware info via Java?

I need to get system and hardware info via a Java application.

I'm interested in:

• Os details;
• Processors count, names, processor load in percents;
• Memory status (total/free);
• Os process (threads) count and CPU/Memory usage for each of them;
• Network statistic (for each interface);

Is there a Java library that can do this?

1. Using Java to get os level system Information will get you started in right direction.
2. Finding Operating System Information
