I need to profile Java programs with following metrics

System time
User time

The JVM is a process like any other - some of those metrics are only valid for the underlying OS. 'top', 'ps', 'time' would be good places to look

what are those where should I look those?'top', 'ps', 'time' would be good places to look
Re: profiling java programs in eclips (Linux Ubuntu)
They're command line tools. 'top' gives you an automatically-refreshing view of all the processes and the resources they're using, plus some aggregate statistics. 'ps' can be invoked a lot of different ways and gives you a list in process-id order. See 'man ps' for more help on ps arguments. 'time' can be used to get a record of how long a Java process took, in terms of user time, wall time and system time. Use it like 'time java MyProgram'.

If you want something visual, try jconsole and jvisualvm - although since they operate at the JVM level and up, they won't give you precisely what you asked for. In Ubuntu System..Administration..System Monitor also has a process list which can give you some per-process stats as well as memory maps and open files in the 'Processes' tab.
