By default, the processes are ordered by percentage of CPU usage, with only the "top" CPU consumers shown. This is much similar to Linux top command but it has some rich features like user friendly interface to manage process, shortcut keys, vertical and horizontal view of the processes and Also go through /proc/cpuinfo file. Assuming your application is running and looks healthy, let’s now check that it is listening for network connections. have a peek here

Finally, you grep the line containing the CPU percentages and then use gawk to sum user, system and nice processes: top -bn 2 -d 0.01 | grep '^%Cpu' | tail -n So, we can run top in batch mode which allows us to parse its output.
