The graphs it produces are the following:

• CPU: graphs idle, user, sys and wait time
• CS: graphs the context switches/s
• IN: graphs the interrupts/s
• IO: graphs the block read and written to disk per second
• Memory: graphs the memory usage (swapped, free, buffers, cache)
• Procs: graphs the number of running and blocked processes
• Swap: graphs swap in and swap out activity
