Disk Utilization

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.

(Report Options). Jump to a detailed dashboard or control panel for:
Device. Device hostname/IP address.
Disk. Disk label (device index in parenthesis).
Size. Disk capacity.
% Used. Average percent of disk used for the selected date range. For understanding how to report the freshest measurements for storage associated with virtual machines, see VM considerations.

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, Virtual Monitoring 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:

% Min. Minimum percent used for the selected date range.
% Max. Maximum percent disk used for the selected date range.
Avg. Average disk space used since polling began.
Min. Minimum disk space used since polling began.
Max. Maximum disk space used since polling began.
Avg Free. Average free space since polling began.
Last Poll. Duration since last sample.

Generate a report

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.

Control	Description
Device	Table/chart(s) of disks and usage metrics. Choose a single device to display all disks and their capacity usage.
Device Group	Ranked list. Choose to return the top-ranked disk with respect to capacity usage for each device in the selected group. You can also create custom or dynamic groups.
Network	Ranked list. Choose to display the top-ranked disk with respect to capacity usage for each WhatsUp Gold managed device.

Control	Purpose
Date Range	Choose or define an overall date range.
Business hours	Focus on specific days of the week and periods within each day. Reveal trends that are sensitive to business hours, time zones, and other periodic attributes in the observed data.

Control	Purpose
Columns.	Click a check box to display the column. Clear the check box to hide it.
Move Column.	Click on a column heading and drag it to reorder your table's columns.

Control	Purpose
Show Top n Items	Limit items to the samples with the highest (or lowest) utilization.
Threshold Type	Switch between minimum or maximum mode for cutoff values for the ranked list. At or Over. Show peak usage period. (Utilization percentage equal to or greater than Threshold.) At or Under. Show usage periods where resources are unused or possibly down. (Utilization percentage equal to or less than Threshold.)
Threshold (percent)	Baseline value used to trim ranked device list based on peak or subpeak capacity when returning the Top n.

Control	Purpose
Display Options	Present data as a chart, a table grid, or both.
Chart Type	Gauge charts. Available when you select a Date Range of Last Polled . Time series. Available when you select a Date Range interval (Today , for example). Line/Area. Scatter graph that connects adjacent measurements with straight lines. Spline/Area Spline. Choose a graph with a smoothed appearance where adjacent samples exhibit a gradual slope.
Chart Options	Legend, Grid Lines, Range Selector. Include legend, grid lines, and range selector for readability. Trend Lines. Present data with a smoothed average to show trend.
