Re: agrigated view of multiple devices

You may want to try using mtargets  with mtargets-ops of  "sum()".   
mtarget is  kind of a virtual target that  is only used by the grapher.
Common to graph multiple data sources in a single graph in this manner.  
This allows you to add/delete targets in future without losing past 
data.  You can also set unknown-is-zero if you want to show missing data 
as 0 instead of NaN.

Sample config
target sumDslLinks
        target-type     =<same target type as your individual dsl targets>
        mtargets        = "dsl1; dsl2; dsl3; dsl4"
        mtargets-ops    = sum()
        unknown-is-zero = true


See http://cricket.sourceforge.net/support/doc/reference.html for more 
detail.
