There are some caveats here which are probably poorly documented:

  - switch names should be alphanumeric only with now spaces or special 
characters (periods/dots, dashes and underscores are all fine though)

  - switch names should be lower case only -> this may actually be your 
issue as you're using Mumbai in one example, change this to: mumbai

  - the aggregate graph name in infrastructures should be alphanumeric only

These are mostly due to crud build up over a ~10 year development cycle 
and we'll try and weed some of these out.

The overall NIXI aggregate graph should work fine if the above are okay 
AND you set the aggregate graph name to a lower case single-word 
alphanumeric at: http://nixi.org.in/ixp/ixp/edit/id/1

This is platform specific. The recommended OS' are FreeBSD and Ubuntu, 
both of which include a service container for mrtg. You'll need to ask 
someone who knows CentOS more than I.

It only really needs to be run after a change. At INEX we do it twice a 
day by cron and manually when we want to rush it.

Aside: over the course of V4 development this will no longer be necessary.
