New question #208411 on Graphite:
https://answers.launchpad.net/graphite/+question/208411


I am net to Graphite and have obviously done something stupid, please help

I have installed 0.9.10 in line with http://graphite.readthedocs.org/en/latest/ and got pretty far, however I am not getting any data.

/opt/graphite/storage/log/carbon-cache/carbon-cache-a/console.log is full of messages like the below.  The files all exist and it does not matter if I run carbon as a user or as root.  If I delete the files they get re-created empty and I get the same error.  

Any idea where I am going wrong?
