Monitoring Large File Systems

By default, Resource Manager uses the Host Resources MIB to monitor file systems. A defect in the implementation of the Host Resources MIB in net-snmp causes file systems larger than 16TB to report incorrect utilization metrics, such that you might observe file system utilization values greater than 100%.

To work around this deficiency, Resource Manager can instead use the UCD dskTable MIB to monitor file system utilization.
