Subject: Re: [Netdisco] perl script for custom reports
Hi Oliver, thanks for the reply.
I was kind of afraid that it would be a new feature...I am stuck on an old
branch due to too many changes I haven't been able to upstream...I may end up
doing something like a custom javascript patch to dynamically create the links
for now or just live with having to copy/paste. Its a custom CVE tracking
database I also host in my netdisco db. Would an old version have an easy way
to define a field to automatically hotlink to eg. the nodes view with the
column value as the url parameter?
As an aside, I've developed a collector plugin that may be useful in this age
of limited-or-no-arp-table devices (Aruba CX is the main culprit for me):
netdisco-flowcollector. I have created a platform file for NFDump, since that's
what I'm using.
It grabs the source mac/ip of every flow with just the SYN flag set and filters
out any macs that are associated with more that one IP or that reference a
known device IP/Alias, which seems to reduce false-positives to basically zero.
I also created a netdisco-apicollector, but the CX series API didn't yield any
better arp data through the API than the CLI so I abandoned the experiment, but
the code is mostly complete and working.
Would there be any interest in the code for this?

Hi Brian
No problem asking again! A lot has been developed in the past couple of years
which might help.
One problem with making anything a hyperlink by using Perl munging is that the
output is then HTML escaped for safety by Netdisco, rendering the link useless.
This is why the old Plugins I released for Observium and RANCID were quite a
bit of work, adding template code and so on.
Since then, we have the new external_links and custom_fields features which
allow these plugins to be entirely replaced by deployment.yml config!
https://github.com/netdisco/netdisco/wiki/Configuration#external_links
https://github.com/netdisco/netdisco/wiki/Configuration#custom_fields
I'm not quite understanding how you attach a CVE number to a device, or do you
mean you have a separate database to look them up in?
Anyway, you can easily nowadays push some data into a custom field (for a
device or port), either via API or in a Hook, and then use that custom field in
a device or port hyperlink, using above config options.
https://github.com/netdisco/netdisco/wiki/Hooks
https://github.com/netdisco/netdisco/wiki/API#update-a-custom-field
If you have another scenario in mind, please elaborate, as this is where the
features come from! :-)
regards
oliver.

Hi list, I know this is a _very_ old thread, but it just kind of ended up with
a link to the Wiki which, while an excellent source of a lot of things to do
with custom reports, still doesn't have an example .pm for column munging.
I'd love to be able to do a few things like make some columns into hotlinks
(eg. CVE numbers going to NIST definitions), but I'm not sure where to get
started with the "munging".

Hi Oliver !
Thanks a lot !
Maybe a Perl script as an example to mung the data that is called up in this
way? I can't see how to access the input for the script, and I don't know what
the output should look like either. I only know that the Perl script should
have the same name as the report tag and must be located under site_plugins.
Thanks in advance,

I created one :) https://github.com/netdisco/netdisco/wiki/Custom-Reports

Probably nice to make a /contrib directory for these folks could drop into a
repo for other user-created reports they find useful.
Reading this thread, I was wondering about looking at making a custom report to
fix nbt node views. It's really quite annoying it doesn't give the ip address
in the main view, would be nice to add a like report with just that if not
adding to the existing one.

Subject: Re: [Netdisco] perl script for custom reports
Hi,
There is a simple way to make custom reports...
My way to create custom reports is to place yml code at the end in
environments/deployment.yml file like this:
reports:
- tag: List_of_devices
label: 'List of devices'
category: Device
columns:
- { name: Device}
- { ip: ip}
- { creation: First_seen}
- { last_discover: Last_discover}
query: |
SELECT name, ip, creation::timestamp(0), last_discover::timestamp(0) from
device
ORDER BY name
After that you can find a report on the web interface "Reports -- > Device -- >
List of devices".
I hope it helps.

Hello !
Can anyone post some simple perl script example for them ?
Thanks a lot.
https://github.com/netdisco/netdisco/wiki/Configuration#reports
You can munge the data retrieved from the database by placing a Perl script
with the same name as the reports key into the “site_plugins” directory of
Netdisco’s home area. The script can access $config for its configuration and
@data for the retrieved data. It should return a list of munged data
