onstat -d chunks perl monitor

I have a file I need to monitor with a perl script with the following format. I need to send off a 0 if it is above 95 in the 5th colum and a 1 if it is below. Any help on a simple perl script would be great.

75424958       999975         983170         /dev/rmetrochunk00 98.32
760c2dd8       512000         511947         /dev/rmetrochunk01 99.99
760c3018       512000         511947         /dev/rmetrochunk02 99.99
760c31f0       512000         511947         /dev/rmetrochunk03 99.99
760c33c8       1024000        969376         /dev/rmetrochunk04 94.67
760c35a0       1024000        867971         /dev/rmetrochunk05 84.76

$a="75424958 999975 983170 /dev/rmetrochunk00 98.32";
@ar = split(' ',$a);

if ($ar[4]>95)
{
print "0 ";
}
else
{
print "1";
}

My example is of the contents of the file so no this won't work.....

Here is a better example.

bash-3.00$ more onstat.log | awk '{print($5,$4)}'
98.32 /dev/rmetrochunk00
99.99 /dev/rmetrochunk01
99.99 /dev/rmetrochunk02
99.99 /dev/rmetrochunk03
94.67 /dev/rmetrochunk04
84.76 /dev/rmetrochunk05
100.00 /dev/rmetrochunk06
99.99 /dev/rmetrochunk100
99.22 /dev/rmetrochunk101
90.93 /dev/rscout_dbs
