Hi Brian,
Wow, that looks great! Yes you're right about the difficulty of maintaining
vendor model specific solutions.
A long time ago (2009 era) I had a patch to Netdisco 1.x which added
"frontpanel" graphics as well. It was a lot of fun to do, and had a cute
XML domain specific language to describe devices and how they should be
visualised (ports, groups of ports, counting direction, line cards,
background images, etc), making full use of the "Modules" (entity) data we
get in Netdisco to find the chassis, ports and line cards. For example:
https://github.com/ollyg/Net-Appliance-Frontpanel/blob/master/share/xml/chassis.xml
Anyway, it was not very realtime and not very easy to get working for lots
of different types of devices.
@brian please do send over to me (oliver at cpan dot org) your patches, I'm
always interested in seeing how different people approach and solve the
same problems and if we can take any ideas forward into new features (with
permission).
regards
oliver.

I've managed to get everything working on Debian Buster
nice!
The only remaining problem I have with this setup is that some of the
reports go away and never come back, just showing "Processing..."
forever. Most of the inventory type reports but also things like "Port
Utilization". Seems like about half the reports aren't working and there
isn't an error that hits any of the logs. Any idea what would have
changed on the underlying perl etc side to wreck the reporting for me?
Any extra debugging I should turn on to help troubleshoot?
You can check the postgres logs to see if an illegal query hits the
database. The file should be somewhere in /var/log/postgresql/ on Debian.
You can enable the developer tools in the browser (e.g. F12 in Firefox),
there is a Console tab there that will show javascript/ajax crashes.
You can start the web server with some debugging and sql output like so:
~/perl5/bin/localenv bash
DBIC_TRACE=1 plackup -p 5001 -R share,lib,~/environments bin/netdisco-web-fg
(this is from https://github.com/netdisco/netdisco/wiki/Developing,
maybe you need to fiddle with the PATH and -R flags for it to work on
the cpan installation instead of the git checkout)
In one of these you should be able to see what's going wrong.
Good luck!
