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.

Device. Device hostname/IP address.
Disk. Disk label (device index in parenthesis).
Size. Usable disk size.
Average Used. Average disk space used during the specified time period.
Average Free. Average free disk space during the specified time period.

Generate a report

Choose device. Choose one or more host devices you want to see 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.)

Filter and reduce by row and by column. Sort and remove columns, group rows based on specific column values, and remove noise and chaff from the table.

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 WMI or SNMP credentials. For more information, see Using Credentials.

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	Purpose
Device	Browse and choose a single device.
Single Interface	Choose an interface on a device.
Device Group	Choose an existing group of one or more devices. You can also create custom or dynamic groups.

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
Sort.	Sort column in ascending or descending order.
Columns.	Pick the columns you want to view. Click a check box to display the column. Clear the check box to hide it.
Group by this field.	Group table into collapsible rows wherever the current column contains identical data ("field") values.
Filters.	Provide a keyword to view only rows that contain the keyword for this column.

Control	Purpose
Show Top n Items	Limit items to the samples with the highest 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 devices at peak or subpeak capacity from the Top n list.

Control	Purpose
Display Options	Present data as a chart, a table grid, or both.
Chart Type	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 (percent)	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.
