filesystem cache metrics in OEM 10g

I've got a report that mamagement wants listing statistics on various hardware resources over time and trending future use. Easy enough, especially with OEM 10g for cross platforms, as I've now got a procedure to query sysman.mgmt$metric_hourly/daily. The problem is with memory, in that as discussed before, normally it shows nearly fully allocated due to filesystem cache. I'd subtract that number out but it seems that OEM 10g doesn't gather that info, at least by default.

Anyone have a good way of dealing with this? Should I create user metric to pull in "vmstat" buff and cache values, used to subtract from used memory to get a more real picture? Seems like a dumb fix but I can't come up with any other way. I know managment won't understand that just because memory shows as 99% used all the time its really not.

Thanks in advance for any ideas.
