Maybe not yesterday, but as long as I can manipulate the time

Can I grab specific Data Sources (cpu_idl) from RRDs::fetch, or would I have to unload the RRD to a file and parse the file with a split or awk?  also how can I combine multiple servers and apply the perl script to all of them at once?  

In the end I just want to be able to gauge a percentage of how much CPU % we are using and what our servers primarily sit at.
