As indicated above, you want to use the EXEC datasource type.

http://cricket.sourceforge.net/support/doc/reference.html#datasource

An example from my configuration is that I have a script that obtains  
the number of current NAT translations from a router. This script  
simply outputs a single number --

$ /usr/local/cricket/bin/check_nat_trans -H my.router.foo
147

Defaults confguration to use it looks like --

datasource nat-trans-ds
         ds-source       =       "EXEC:0:/usr/local/cricket/bin/ 
check_nat_trans -H %router%"
         rrd-ds-type     =       GAUGE


targetType nat-trans
         ds = "nat-trans-ds"
         view = "Nat Translations: nat-trans-ds"

Target definition to use it looks like --

target --default--
   router = my.router.foo

target Nat_Trans
   display-name = Nat-Trans
   long-desc = "Total Nat Translations"
   target-type = nat-trans
