Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Add the "resource metric graph" portlet to dashboard (either global or resource specific)
2. Click on the live data icon in the top-right corner.
Actual results:
uncaught exception in the message center

Expected results:
no exceptions

Additional info:

The problem is maybe two-fold.  The exception results from not protecting
against an empty metric value return.  I will fix this.  The second
problem is that there really shouldn't be an empty value returned.

Interestingly, Lukas was just "lucky" in that the graphing actually
seems to work for all resource types other than the one he used: CPU.
At least all the ones I tried until I asked him what he used :)

So, with the fix for problem 1 the graph does not generate an exception
but it also does not display any data.  I'll look at seeing if 
CpuComponent can be tweaked to provide something for a live data
request.  The issue is due to the fact that we already do some
complex work to generate CPU metrics.

master commit 69e2b1d81dc42b0bfc12ee8e32b08d7b2beba38d

- Fixed the live graph code to throw out metric requests returning no values
  so we should be safe from the type of exception reported.
- Fixed CpuComponent to return valid data on a live metric request, instead
  of null, so CPU resources should now give proper live graphs.
