Would it be possible to have Site24x7 report the current value that is reported back for any server Check e.g. file size, folder size.

Site24x7 must receive this value to determine if a threshold  has been exceeded therefore the value should be able to display within the portal.

This would also be helpful (if the polled values are recorded) to determine the rate of growth/change in value

With MIBS on network devices it is possible receive a current reported value to test that a meaningful value is received.
