[Root@xen-host01 ~]# sh/opt/tools/real_time_status.sh

The default is sorted by outgoing traffic (column fourth), displaying the top 6 names.

If you want to sort by a different column, connect the column numbers directly after the script, and if you want to display more virtual machines, then the number of items to display after the column number.
The following commands are sorted by IO read requests (column fifth), displaying the top 10:
[root@xen-host01 ~]# sh/opt/tools/real_time_status.sh 5 10

Note:
Default does not show the virtual machine CPU utilization, if you want to display, please edit the script, the following two lines of comments (#) removed, save exit, and then execute the script.
