    @markap14 - Counters are currently protected in access policies using a 
global resource. This is due to the fact that there are instance based Counters 
and a corresponding type based Counter. The type base Counters aggregate the 
values from all instances of that type reporting that Counter. Because type 
based Counters lose the association to the underlying instance, we are 
currently requiring a global permission. 
    
    Access to stats and status history is available to any user with 
permissions to the UI (protected in access policies with the /flow resource). 
Because of this, I think we need to filter only allowable Counters into the 
status history. We will need to decide what is allowable in this context.


> Processor Counters should be included in the Status Reports

> This would allow a Processor's Status HIstory to show counters that were 
> maintained over time periods instead of having only a single count since 
> system start.
