Ok cool
J
I will spend some time gathering the OID’s for at least the LDP and BFD adjacencies as soon as I get a spare moment then. And can think about the MPLS service
related ones later.
Completely agree that the db schema needs to be logical, so fingers crossed the OID mappings are reasonably consistent across the main vendors at least, to allow
easy injection into a schema.
And in the mean time we will remain quietly hopeful that “circuit-id” groupings might be pondered over for the Core page ;)
Thanks again for your thoughts,
Andy.

I think an LDP/BDF/CDP requirement for this to work is reasonable. Make use of data that’s already available per-device vs. trying to reinvent the wheel.

This is actually all stuff I wanted to do too last time I worked for an SP/Telco. Most of it was "definitely going to add in the next 6 months",
but since I stopped having a network, it's difficult to do.
All of these things are ok to add, but you need to build database schemas which can be used for multiple vendors, otherwise they end up being abandoned.
LDP and BFD seem the easiest, they're just another per-port thing. If you look at a bunch of vendor mibs for these things, you can work out what
needs to be stored for all of them, and we can come up with a table schema.

Hi Adam,
A CDP/LLDP driven page sounds nice. How would you envision it?
Would it be a dedicated “Links” page that shows graphs like the existing “Core” page, but with only a single graph per logical link?
Or an enhancement to the existing Map where you could hover over the link and the Graph appears?
Naturally it’s your project and I’m sure you already have future plans in mind for how you want things to be, but I’m thinking that adding in some logic to the existing Core page to group/merge links which have the exact same ‘circuit-id’ string would give more control to the admins?
Many people (including ourselves) may not be able to run CDP or LLDP everywhere due filtering on pseudowires, EVPL circuits etc which do not support them, or just because of security policies etc.. L
I built an Observium system for my previous “Enterprise” employer, but I’m now working for a small Colo/Service Provider, and so I’m thinking about scaling with Observium. This is one of the first things that came up to be able to view links as links, and not just multiple ports.. J
Also if I was to go and spend a bunch of time working out all the OID’s and how they all map together, would you be receptive to adding some extra pages for things like displaying;
- LDP Sessions (Protected and Targeted) – Ideally with ability to alert on unprotected and failed sessions
- VPLS Instances with VFI MAC address counters
- Traffic Engineering Tunnels and RSVP info
- BFD Neighbors
Thanks for your time and work on this project J
Cheers, Andy.

This would be best done as a page which showed cdp/lldp/etc "links" as opposed to the core page, which his based on port descriptions. We already use this logic when drawing the map, so as not to draw links twice.
We don't have such a page yet, but it probably wouldn't be terribly difficult to create.

Maybe you could also include something about an A and Z side of
each link. This won't work directly with the port description
parsing, but you could easily make a group of A side links and
use the group for aggregation.
