Disk Utilization reports compare disk storage capacity to actual utilization for devices with on-disk storage. These reports are useful for assessing current needs and predicting future trends for storage resources.
Tip: If you want to return disk utilization metrics for a Hyper-V guest VM, you must enable the VM to record WMI or SNMP metrics as described in a community article titled Hyper-V Disk Utilization Information May Not Be Available. Outside of this requirement, WhatsVirtual also includes read/write metrics in the Virtual Machines Disk Activity report.
To display additional measurements, click a column heading () for column selection (). You can also include:
Choose Device. Choose one or more host devices you want Disk Utilization measurements for.
Choose time constraints. (,) Choose times for the Disk Utilization. (For recently observed measurements, select Last Polled from the Date Range drop down list.)
Choose, filter, and reorder columns. Choose and hide columns, reorder columns, and customize your data view.
Chart, adjust output, and visualize. Fine tune report presentation and range of values displayed using the Report Settings dialog (optional).
Note: This report only returns disk utilization metrics for devices that already have the appropriate performance monitoring enabled. To enable these polled measurements, see Disk Utilization Monitor.
Tip: You can gain access to "root" (/) partition metrics for Linux and UNIX OS by using the SSH Monitor or by assigning the SNMP user (as designated in snmp.conf) with appropriate Sudoer privileges. Disk utilization measurements for a Linux or UNIX "root" partition (/) are at first typically not included in this report. When "root" (/) partition totals are not included, total disk capacity in the report typically appears 5% less than the physical disk.
Most generated Disk Utilization report data can be printed, shared, and exported when selecting Expand () from the Dashboard Options () menu. After the report has been expanded, select export () to access the following options:
