Storage Monitoring/Reporting?

Hi.

How do you guys, monitor/report your Storage environment? I have people (don't we all? ) that like to have monthly reports on space (raw/assigned/available), ports available/used, switches and the such.

Do you use anything special? Or are you like me, a nice big Excel spreadsheet? How about something like Onaro's Sanscreen? Other solutions out there that you know of/use that could do the job?

Thanks.

this depends on what hardware you have, what you can program/script for yourself or how much money you are willing to spend...
