This may be something stupid, but I'm trying to just write basic reports and I can't seem to find any documentation anywhere on the basics.
I am trying to write a report that will show me all of the Max bits per interface and I'm ending up with the Ki and Mi. Ideally I would like to to see a max % utilization, but I haven't been able to get that far yet.
thanks in advance
Here's what I have....

Ki and Mi .... standardized, binary prefixes. 
Ok, back to your task. At first switches and routers usually return bytes not bits. So in this case we've to multiply it with 8 to get Bits/s. To calculate the max. utilization we've to see the maximum traffic in relation to the bandwidth, which results in :
"f_max*8/maxValue".
IMO it's recommend to use decimal SI-Prefixes in this case.
Best regards

| That seemed to do it. Is there a way to sort the data as it's coming up.

Ooops, I took a look at the formula and saw that we've forgotten to multiply it with 100. At the moment you should get something like '0.45'.
So change it to "(f_max*8/maxValue)*100".
Sorry, but I didn't understand your second question. Maybe I should drink a cup of coffee first.  Have you seen the arrows right beside the unit, which allow to sort the results?
Best regards

... my coffee is ready!

Dear browniebraun.
First of all I want to thank you for your good work and your excellent plugin reportit.
As far as I can see it works very good for most of the people.
But I have got a problem that many others have too.
I and many others need documentation or a howto.
It would really be kind of you if you could find some time to write at least some introducing stuff for beginners like me, explaining some basic steps to a report and working with measurands or variables.
Thank you in advance
Frank
