Do you have like these questions with you?
-> Say there are 500VM, how do you check health of all 500VM without ping cmd?
-> How do you see number of open files without using lsof cmd?
ping can't check the VM health status, you can use VMWare tools to check the VM health status or you can use Monitoring tools to check 500 VM health status.
lsof is only the command to see the open files, i do not know without the command how to check open files.
