Hi Morten,

Thanks for responding. Graphite-carbon was installed via the Debian package while the graphite-web was installed using pip. I was able to trace the source of the problem to the webapp's config file as suggested. I ended up performing a new install on a different machine in an attempt to save some time.

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.

Thanks for your time.

Sincerely,

Ukeme Noah

This error usually means NAV has a problem contacting the Graphite web
interface. Is the base URL specified correctly in NAV's `graphite.conf`,
and is that IP address/port combination open for for access from the NAV
server?

That is, however, a bit strange. Did you install all the Graphite
components (whisper, carbon, graphite-web) using pip or Debian packages?

If your data is in `/var/lib/graphite/whisper/nav`, it sounds like you
installed the graphite-carbon Debian package. Then you say you have
`/opt/graphite/bin/run-graphite-devel-server.py`, which sounds like you
installed graphite-web from source or using pip.

Is graphite-web correctly configured to look for whisper files in
`/var/lib/graphite/whisper/`, or is it looking in
`/opt/graphite/storage/whisper`? Under Graphite's typical /opt layout,
the webapp's config is found in `/opt/graphite/webapp/graphite/`.
