We have a corporate environment with 35+ varying logical business units
amongst which we assign various subnets.
We have a table (call it our_networks) which maps network (type CIDR) to
Business unit (bu type text) and State (state type text).
We need to perform searches/run reports against all devices in a given BU.
Trying to do this we end up having top make 35 reports and make a new one
every time we add or subtract a bu. it would be preferable to be able to
make a single report, add a field to devices for the bu, update that bu via
nightly task and add a dropdown on the sidebar allowing filtering based on
unique bu values. I've tried as few approaches but have been bouncing off
this wall for months like a racquetball. I'm not finding a means of adding
this bu to devices and making it filterable without significant base code
changes.. am I missing something? I'm starting to feel like I missed some
simple detail.. I did add bu to our netdisco devices table as part of my
efforts and populated it as well. so the database part should be addressed,
it's just the display and filter part that has me baffled.

We are having a serious problem in latest versions: I can't see IP
addresses in device info; a switch list shows only mac addresses at
ports and some private IP addresses (not all), but public addresses are
not provided.
Interestingly, this only happens to remote campuses. The Netdisco server
is at campus A but it monitors both campus A and remote campus B. The
issue happens only with devices at campus B.
I am not sure at which version it started. I am also not sure if it is a
Netdisco-caused problem or it is pertinent to our environment.
We have had some ISP-related changes lately at campus B edge, but they
should have affected only the physical layer.
I have not changed (as far as I can remember) the Netdisco configuration.
I did a fresh Discover All, ArpNip All, Macsuck All without success (on
campus B devices).
Netdisco info:
-------------------------------
Software Version
App::Netdisco 2.44.3
SNMP::Info 3.70
DB Schema 61
PostgreSQL 11.00.5
Perl 5.10.1
66 devices with 140 IPs
1,844 interfaces of which 906 are up
55 layer 2 links between devices
3,278 nodes logged, of which 1,826 are active
12,750 IPs logged, of which 5,740 are active
Statistics last generated on 2019-10-23
Do you have any ideas on what may be wrong? What should I check and what
should I try?
This is important, as it seems I have lost not only current, but also
historical data of real IP Address usage on remote site (campus B). IP
inventory / Subnet Utilization reports (for subnets used at campus B)
are empty. Shouldn't such reports still display older IP Addr usage data?
Please advise!
Thanks in advance,
Nick

Hi Joe
I'm probably not seeing the whole picture yet. If you just add a report
like shown in
https://github.com/netdisco/netdisco/wiki/Configuration#reports
E.g.
reports:
- tag: power_inventory
label: 'Power Supply Inventory'
category: Device
columns:
- {name: 'Name'}
- {ps1_type: 'PS1 Type'}
- {ps1_status: 'PS1 Status'}
- {bu: 'Business Unit'}
query: |
SELECT d.name, d.ps1_type, d.ps1_status, d.bu
FROM device d
ORDER BY name
and then filter the BU with the "Filter records.." box in the HTML page,
what is it exactly that you're missing from there?
In general, if the simple reports configuration in deplyoment.yml
doesn't cut it, you might have more luck with making a specific Web
Plugin as described in
<https://github.com/netdisco/netdisco/wiki/Web-Plugins>.. but maybe
you've looked at this already as well?
If you can post some details of where you're stuck at, what these
searches/report exactly should contain etc. we can give you better advice.
Cheers
Christian

Hey All I’ve been messing around with this, is there a way to change the
way port count shows? In some cases ports might be down but configured and
would like this excluded from free ports.
Also is there a way that I’m able to report a cost metric on a given
interface for isis costing?
