swapoff -a as root to swap all memory back in. Don't forget to run swapon -a afterwards to make swap available again. Note that swapoff will fail if there is not enough physical memory available to swap everything back in.

how to monitor that i have tried this commands sar -r/sar-s both not showing the swap memory details and too SI and SO. right now temporarily rebooted the server and swap memory back to 0 dont know whether it will be fix or not.
