Have you confirmed that carbon is actually getting data? There are a couple of ways to do this:
* Look for .wsp files corresponding to your metrics. They should be in a directory structure similar to the metric name beneath /var/lib/carbon/whisper/ or /opt/graphite/storage/whisper.
* ls those files. When were they last updated? If it's not recently make sure carbon can write to them. (don't forget SELinux)
* Try tailing /var/log/carbon/*. See what pops up. Pay special attention to /var/log/carbon/listener.log as this should have an entry when carbon receives data.


If the above doesn't get you anywhere dump some of the data in those files using /usr/bin/whisper-fetch.py. Look for null values. This may indicate a problem with your aggregation rules.
