setHistoryLimitForAttribute help please.


I am doing something very basic and have been struggling for a few days now.  I am just trying to set history for an attribute and view the history.  I am sure it is a user error and would love for someone to slap me upside the head and let me know what I am doing wrong.  I googled for this and could not find anything helpful.  

All I am trying to do is get historical information about the OperatingSystem/SystemCpuLoad attribute.

I know this is a user error, as it is very basic, but I am at a total loss on how to get history to show up on the read operation.  If anyone can help me out I would be very grateful!!
