I've been plotting the this value by MRTG with a small script

My MRTG page is
http://cache.jp.apan.net/MRTG/cache01.jp.apan.net/hitratio.html

The script is http://cache.jp.apan.net/script/MRTG/hit

One problem is that occasionally ServerInKb is bigger than HttpOutKb,
therefore, the return value is negative.
