--- Begin Message ---
well, the table device_port_properties keeps all interfaces it seems, so i can
just diff those against device_port.
perhaps i'll just extend device_port_properties with 'ignore_reason' or
something....

Nick,
As an idea - Add debug flag to your .yml config file and grep it later?

ok, so 2 minutes later i see i'm testing with the wrong config.
netdisco-do discover -D shows the interfaces being removed:

so that only leaves me with question 4: how do i get a list of removed
interfaces?
thx

Subject: [Netdisco] how does ignore_interfaces work
heya,
a few questions about how the ignore_interfaces setting is supposed to work,
since i'm getting back more interfaces as expected.
1) are interfaces listed here supposed to be not discovered and thus not added
to the inventory, or are they discovered, added to the inventory but further
ignored?
2) is it supposed to work on all devices or only on select snmp::info classes?
3) what's the difference between i_ignore & if_ignore? netdisco seems to use
i_ignore only, but snmp::info only has i_ignore for a few modules, snmp::info
seems to use if_ignore for that purpose:
https://metacpan.org/pod/SNMP::Info#$info-%3Eif_ignore()
4) how do i actually get a list of ignored interfaces? i checked on several
devices but they all turn up empty lists. one of the devices i tested on is a
oneaccess router, which has i_ignore overrides in it's snmp::info module, but
even there i'm not getting anything back from i_ignore, if_ignore or the module
specific version:

i did add a few extra ones in my configuration, but it seems they parsed
correctly?

another example is a cisco router with a bri interface. ignore interfaces has
"BRI\S+-Signaling", but it still shows up (did a new discover just to be sure):
