New question #217200 on Graphite:
https://answers.launchpad.net/graphite/+question/217200

I'm polling ifHCInOctets (64bit counter) from a switch via SNMP using collectd 5.1.0, writing to Graphite 0.9.10. Data is getting in fine, and I see an ever-increasing line on the graph. If I apply derivative() as the documentation says to, I have no data. Looking at &rawData=true, it clearly says 'none', yet the data was certainly there before the function was applied (looking at rawdata=true again).

I must be missing something. Any suggestions?
