[ixpmanager] Multi IXP - Graphing

[Mike Hammett]

We've just done each IX as a separate install. Maybe we should have done separate infrastructures. *shrugs*

The history of multi-IXP functionality is that it was added under a 
commercial support arrangement with an organisation that never ended up 
using IXP Manager. 

Multi-IXP functionality is not functionality that INEX / the main 
developers want or need and nor is it something that the core target 
market for IXP Manager needs. The core/target market being small to 
medium IXPs. 

The unfortunate reality is that we have a feature list as long as our 
arms of things we want and need and so there is no possibility of that 
specific functionality being re-implemented in v4. 

It's not all dark and gloomy though:

We have conscientiously dropped support for the explicit "multi-IXP" 
functionality. There is too much overhead and too little time to 
maintain code that is not core to the project. 

But:

In the main, multi-IXP functionality provided ways of generating 
configuration for ancillary services on a per-IXP basis. As we move 
stuff from the older code base to the newer code base, we've generally 
stopped doing stuff on a per-IXP basis and now generate scripts as 
appropriate on a per-infrastructure or per-VLAN basis (VLANs being 
children of infrastructure). 

In other words, the multi-IXP functionality is mostly implemented by 
using infrastructures. 

One of the few things that I can think of that this doesn't include is 
graphing which, right now, is an 'all or nothing' system. 

We have however written a new graphing backend: 

http://docs.ixpmanager.org/features/grapher/ 

It should be relatively easy for an experienced PHP programmer to copy 
the MRTG backend to create a new one that works on a per infrastructure 
basis. 

If you want to do this and the code is fit for purpose, we'd be happy to 
accept a pull request that includes: 

- the code 
- updates to the documentation 

See: 

https://github.com/inex/IXP-Manager/blob/master/CONTRIBUTING.md 

To ensure a PR is successful, it would be advisable to link in with us 
on the planned methodology. 

Cheers, 
- Barry
