I am trying to get the current (not the average) free memory size of SUN SPARC remote server, but I don't have the permission to use free -m
command or prtconf
. So, I used command vmstat 2
and the result is
kthr memory page disk faults cpu
r b w swap free re mf pi po fr de sr vc vc vc vc in sy cs us sy id
0 0 0 46981864 20824288 311 416 51 1 1 0 0 27 6 0 18 16070 33290 17580 12 2 87

and vmstat| awk '{print $5}'
and the result is 20824288 which is the average not the current value ,so how to get the actual value ?
