We've been using NAV 4.3 for a while now. Then after upgraded to 4.4.3, there no graph data. What when wrong?

You don't offer a lot of information to go on here.

* What OS version are you using? * Did you install NAV from source or from a package? * Did you set up Graphite on the same server as NAV, or on different one? * Which version of Graphite are you using? * Are there any errors in ´ipdevpoll.log´? * Are your graphs just empty, or do they display an error, or do they not display at all? * Are you able to browse the graphite-web interface yourself?
