How to check swappiness value on Linux Box.



[root@sankar-test ~]# cat /proc/sys/vm/swappiness
60 -- default value



FYI,
swappiness can have a value of between 0 and 100

swappiness=0 tells the kernel to avoid swapping processes out of physical memory for as long as possible

swappiness=1 tells the kernel to Minimum swappiness without disabling it entirely

swappiness=100 tells the kernel to aggressively swap processes out of physical memory and move them to swap cache

swappiness=60
(default) the swap file will be used fairly often if the memory usage is around half of my RAM.
