Also, if you own a M-series appliance that you use in conjunction with the C-series and X-series and centralized reporting/tracking, you can see the current disk usage in the web and the CLI.
For the M-series on the web, you can go to "System Administration > Disk management" and see the total space allocated for the services.
For the M-series on the CLI, type "diagnostic > disk_usage" to see how much disk space each service is using.
Just wanna thank to IronPort for this new numbers about the system (Monitor, System Capacity). This informations are really helpfull.
