I often have several java programs running and I can't tell which one needs to be killed. The command section of the process table only shows java, but doesn't tell me which jar or class files it is running. Edit: Is there a way to see more of the command call from withing KSysGuard?
A GUI alternative to Ksysguard is qps. It's perhaps less visually appealing that ksysguard, but it shows a lot more information, including the whole command line.
