Hi,
We are running NAV 5.6.0 (from av Debian package) on a local Debian 11 machine, set up with postgresql and apache2. Initially we had some problem with the error message "Graphite unreachable", but followed the solution suggested by datagutten: https://github.com/Uninett/nav/discussions/2535
Now, a lot looks nice. Graphs display fine, but we have problems with Netmap, which is empty.
For the router e.g. the "Ports" tab is missing info about "To Device" and "To Port". "Port details" do not provide any options for "Two IP device".
Regards, Ole Harald
