It looks like you are monitoring the total number of seconds.
This is a COUNTER so you should definately drop the GAUGE option.

There is another problem.
You are monitoring something that won't update more than once a
second. Therefore, when dividing it by the number of seconds, you
will always get a number below one. MRTG will round this down to
zero.

Problem number three: You've defined maxbytes. How can you be sure it
won't go over 100 ?


So:
Drop the gauge and maxbytes.
Start using per minute or perhour, or multiply by 300.

Alex
