I'm meassuring the commited RAM on my server
It gives perfect values but....

let's say you've got 6000 mb total and MRTG measures 1500 used
then there's 4500 avaiable I want to let this value get calculated automaticly in my HTML page
Any ideas on how this can be accomplished

A=total
B=commited
C= available

A - B = C

Is it possible to use these values as a variable one????????
and make it appear next to the graph in my html page

Some way to make calculations would be good as wel

for example that i can take my maxbytes value minus my target value so i got the available bytes but i don't have any idea how this could be done in the cfg file

for example :

i've got 6000 max bytes and the OID logs a value of 1200
is it possible to do : maxbytes - OID value = what I Need

and then place that value in an alternative place in my HTML file

HTML does not support calculation on fly as it is not a computer language like php or perl. However it is possible to modify the perl code (mrtg) to do this job
