I had this problem 3 years ago and didn't quickly find a MIB which exposed CAR's byte counts. Netflow data collection works and you can create the same groupings of traffic that your CAR policy has though depending upon the complexity of the policies it is extra lifting. Netflow combined with a changing need meant I didn't need to spend time finding the CAR data. The router is collecting it as you can see the byte counts in "sh int rate" output. Some folks find traffic %'s to fit their needs fairly well. I don't like it much but you could take the % of total traffic that is CAR'ed in each class and use that to make approximate guesses to the volume of any given CAR class in any sampling period. Really not a lot of fun and not very accurate, if you're CAR'ing traffic to keep it under control, you've probably shifted some of that offered demand into other time periods. Thus, the colored glasses you use to look at the data this way over estimates the usage of a CAR class during overall peak demand periods and underestimates the amount of CAR'ed class during the overall low demand periods. I'd be interested in hearing if the CAR byte counts are exposed in any MIB. Or hearing about what you decide to do to solve your need.
