The output of the free command that I fired on my linux host is as belows:
free
total used free shared buff/cache available
Mem: 263846320 47746620 3290072 1140808 212809628 214382420
Swap: 0 0 0
I am not able to figure out what this available part is specifying. The free memory is very less shown i.e around 1.24% even though the total memory is way high and used memory is around 18.09% only.
free -h
total used free shared buff/cache available
Mem: 251G 45G 3.1G 1.1G 202G 204G
Swap: 0B 0B 0B
Does it mean I wont be able to start more applications as free memory is very less. The used memory is 18% only. So shouldn't free memory be 72% and not 1.24% as the command is showing above.
I am confused. Can anyone help?
