We ended up in large part developing our own tools in-house.

One is an SQL database to store and link network elements (routers,
interfaces/ports, circuits, IP addresses, contacts, etc) with hooks into
other internal databases and other outward-facing applications, such as
our rwhois server.

Another is a tool that polls our network devices once every few hours and
backs up their configuration into an RCS filestore so we have journaling
capabilities.

We do use some commercial tools, but those are mainly for customer
presentation (VitalSuite) and up/down reporting and event correlation
(Netcool).

jms, your message highlights the extent to which various systems with different
missions in life come to interact with one another - 0R NOT. To wit, event
correlation, network performance, line and port configs & inventory, etc. What
I've not seen here spoken about much (if at all) has been the link between
billing systems and all of the above. I recently undertook to reconcile billing
discrepancies for a business unit in a large corporate account (a very large intl
bank with 132 pops around the globe), and I found that there was no linkage
between their *multiple,* internal bill-back systems (which naturally factored in
markups to leased line costs that are paid by IT) and the circuit inventory
systems. This has to be an issue with BBPs and ISPs, too, I'd imagine, if
accurate and up to date billing is an interest. The manual processes that I had
to endure in tallying the live circuit charges, and separating those charges from
those being assessed for the "dead wood pile" were quite unbelievable in this day
and age.
