Cricket Summation

I have a number of routers, each with an interface to an upstream provider. I'd like to show a graph with the three providers aggregated. This is a config I did to do so:

target --default--
   devicename           = statistics
   directory-desc       = ""
   interface-name       = ""
   long-desc            = %short-desc%
   short-desc           = ""
   target-type          = standard-interface

target ProviderAggregate
  mtargets  = "/routers/router1/fastethernet2_0;
               /routers/router2/serial1_0;
               /routers/router3/atm2_0.1-aal5_layer"
  mtargets-ops = "sum()"
  short-desc "sum(Prov1, Prov2, Prov3)"

The above is the content of a file located in the /routers subdirectory. This turned out to be easier than I thought. The file needs the target --default-- section to start. Then one or more of the aggregate targets can be present. The 'mtargets' simply needs to know the directory and interface. The basic Default configurations in each subdirectory were created with devConfig tool from Acktomic.
