1. Referencing an external database? (Johnson, Neil M)

--- Begin Message ---
Is there a way to integrate data from an external database into Netdisco?
I'd like to include information for our facilities management system so that
when someone looks up a node or device they can see information like the jack,
room, and building information for the switch port.'
Is there a way to do this? I'm willing to put some effort to figure it out.
Thanks!

Hi
Yes there is something called "custom fields", which you can set on
various things:
https://github.com/netdisco/netdisco/wiki/Configuration#custom_fields
E.g. we use this to put some information from ACI/APIC into the datbase,
with sql like
UPDATE device_port
SET custom_fields = jsonb_set custom_fields, '{dn}',
'"topology/pod-1/node-102/sys/phys-[eth1/26]"' ::jsonb
WHERE ip = '10.5.1.22' AND port = 'Ethernet1/26';
The tricky bit is when and how to run this SQL. The best option is to
put it into a discover hook
(https://github.com/netdisco/netdisco/wiki/Configuration#hooks), it will
run whenever a device is freshly discovered or updated.
Another option is to use "external links":
<https://github.com/netdisco/netdisco/wiki/Configuration#external_links>.
As the name suggests they don't show attributes directly but just add a
link to another system, but they are easier to deal with. Plus they work
for nodes as well while custom fields currently don't.
Cheers
Christian
