ISIS Monitoring & Visualisation Requirements

Hi,

I am currently doing some research into the monitoring and visualisation requirements for networks running ISIS. I am primarily interested in what you feel are the key requirements for monitoring and viewing ISIS within a network and why? (I guess it would include stuff like Adjacency and DR changes & area, mesh group, DR visualisation etc).

If you could let me know your thoughts that would be most useful.

regards,
Matt.
