The new install was successful and Graphite appears to be working properly. NAV on the other hand renders system metrics graphs but returns empty graphs for port metrics even though Graphite (via browser) presents no issues with port metrics rendering. Given this would probably fall under a rendering issue, I'll see what I can find in the archives on this. Will send out an email in the event I'm unable to sort the "port metrics" issue.
Is your Carbon correctly configured with the `storage-schemas.conf` supplied by NAV? If not, your Whisper files will have been generated with the wrong schemas, and that will impact the port stats worse than the system stats - the default resolution in Carbon's config, I think, is 1 minute interval data points, while NAV port counters are only collected every 5 minutes, and displayed using Graphite's derive-functions. That may cause your graphs to look pretty empty.
If your Whisper files have the wrong schema, the only useful way to fix it is to install the correct Carbon `storage-schemas.conf`, restart Carbon and delete all the Whisper files in the nav subtree.
