 'cpu_host' can monitor the cpu usage of the host-machine/virtual-machine. It makes use of /proc/stat command for 60 seconds and redirect the command output to a text file. Then sum the required column values from the text file using ’awk’ command and calculate the cpu utilization (%) per minute.
 
-'cpu_host_process' can monitor the cpu usage of a process running on a host-machine/virtual-machine. The script is written to monitor the cpu usage of the Virtual Box VM process running on host. It makes use of /proc/<\pid of the process>/stat for 60 seconds and redirect the command output to a text file. Then sum the required column values from the text file using ’awk’ command and calculate the cpu utilization (%) per minute. U_server_5 is the Virtual Box process name, for which the cpu utilization (%) per minute is desired to calculate. vbox.txt is the file name to which the output is redirected. 
+'cpu_host_process' can monitor the cpu usage of a process running on a host-machine/virtual-machine. The script is written to monitor the cpu usage of the Virtual Box VM process running on host. It makes use of /proc/(pid of the process)/stat for 60 seconds and redirect the command output to a text file. Then sum the required column values from the text file using ’awk’ command and calculate the cpu utilization (%) per minute. U_server_5 is the Virtual Box process name, for which the cpu utilization (%) per minute is desired to calculate. vbox.txt is the file name to which the output is redirected. 
 Note: Change the name U_server_5 to the process which the cpu utilization (%) per minute is desired to calculate. However, changing the file name vbox.txt is optional.

+The scripts are written to estimate the utilization of cpu and memory till 60 seconds. However, the number of seconds can be scaled in the 'for' loops by editing its condition to: for value in {2..(mention the number of seconds)}.
