How to determine total size of ASP.Net cache?

I am looking at my performance monitor and under the ASP.NET Apps v2.0.50727 category I have the following cache related counters:

Cache % Machine Memory Limit Used

Cache % Process Memory Limit Used

There are also a lot of other cache related metrics under this category.

These should be able to get you the percentage, then if you can get the total allowed with Cache.EffectivePrivateBytesLimit or some other call you should be able to figure it out. I do not have personal experience with these counters so you will have to do some research and testing to verify.

Here is a quick start article on reading from performance counters:
