we have in our cluster more then 800 rhel machines - version 7.2
since lsof | wc -l
take too much time ( sometimes 3-4 min ) , in order to get the current open files
we want to know if there are other approach that can give the total current open files in short time
note - in our case , we have 835 linux machines , so it will be very bad to use lsof | wc -
l on all machines , according to our calculation it will take 40~hours
