The data definition process includes adding properties, metrics, policies, or data that adapters provide to a view. These are the items by which vRealize Operations Manager collects, calculates, and presents the information for the view.

To add data to a view, select Content > Views in the left pane. On the Views toolbar, click the plus sign to add a view or the pencil to edit the selected view. In the workspace, on the left, click Data. If you create a new view, complete the required previous steps.

If you selected more than one subject, specify the subject for which you add data. Double-click the data from the tree in the left panel to add it to the view. For each subject the data available to add might be different.

The data configuration options depend on the view and data type that you select. Most of the options are available for all views.

Data Configuration Options

Configuration Option

Description

Metric name

Default metric name.

Available for all views.

Metric label

Customizable label as it appears in the view or report.

Available for all views.

Units

Depends on the added metric or property. You can select in what unit to display the values. For example, for CPU|Demand(MHz) from the Units drop-down menu, you can change the value to Hz, KHz, or GHz. If you select Auto, the scaling is set to a meaningful unit.

Available for all views.

Sort order

Orders the values in ascending or descending order.

Available for List view and Summary view.

Transformation

Determines what calculation method is applied on the raw data. You can select the type of transformation:

Minimum. The minimum value of the metric over the selected time range.

Maximum. The maximum value of the metric over the selected time range.

Average. The mean of all the metric values over the selected time range.

Sum. The sum of the metric values over the selected time range.

Last. Ignores all the data except the data you receive most recently and that is within the selected time range.

Standard Deviation. The standard deviation of the metric values.

Metric Correlation. Displays the value when another metric is at the minimum or maximum. For example, displays the value for memory.usage when cpu.usage is at a maximum.

Forecast. Performs a regressive analysis and predicts future values. Displays the last metric value of the selected range.

Available for all views, except Trend.

Data Series

You can select whether to include historical data, trend of historical data, and forecast for future time in the trend view calculations.

Available for Trend view.

Series Roll up

The time interval at which the data is rolled up. You can select one of the available options. For example, if you select Sum as a Transformation and 5 minutes as the roll-up interval, then the system selects 5-minute interval values and adds them.

This option is applicable to the Transformation configuration option.

Available for all views.

Projects

A project contains scenarios and is a supposition about how capacity and load change if certain conditions are changed without making actual changes to your virtual infrastructure. If you implement the project, you know in advance what your capacity requirements are.

Available for all views. Depends on the selected metrics and properties.

Use the time settings to select the time interval of data transformation. These options are available for all view types, except Image.

You can set a time range for a past period or set a future date for the end of the time period. When you select a future end date and no data is available, the view is populated by forecast data.

Time Settings Options

Configuration Option

Description

Time Range Mode

In Basic mode you can select date ranges.

In Advanced mode you can select any combination of relative or specific start and end dates.

Relative Date Range

Select a relative date range of data transformation.

Available in Basic mode.

Specific Date Range

Select a specific date range of data transformation.

Available in Basic mode.

Absolute Date Range

Select a date or time range to view data for a time unit such as a complete month or a week. For example, you can run a report on the third of every month for the previous month. Data from the first to the end of the previous month is displayed as against data from the third of the previous month to the third of the current month.

The units of time available are: Hours, Days, Weeks, Months, and Years.

The locale settings of the system determine the start and end of the unit. For example, weeks in most of the European countries begin on Monday while in the United States they begin on Sunday.

Available in Basic mode.

Relative Start Date

Select a relative start date of data transformation.

Available in Advanced mode.

Relative End Date

Select a relative end date of data transformation.

Available in Advanced mode.

Specific Start Date

Select a specific start date of data transformation.

Available in Advanced mode.

Specific End Date

Select a specific end date of data transformation.

Available in Advanced mode.

Currently selected date range

Displays the date or time range you selected. For example, if you select a specific date range from 5/01/2016 to 5/18/2016, the following information is displayed: May 1, 2016 12:00:00 AM to May 18, 2016 11:55:00 PM.

You can break down data in List views by adding interval or instance breakdown columns from the Group By tab.

Group By Options

Option

Description

Add interval breakdown column (see data for column settings)

Select this option to see the data for the selected resources broken down in time intervals.

In the Data tab, select Interval Breakdown to configure the column. You can enter a label and select a breakdown interval for the time range.

Add instance breakdown column (see data for column settings)

Select this option to see the data for all instances of the selected resources.

In the Data tab, select Instance Name to configure the column. You can enter a label and select a metric group to break down all the instances in that group. Deselect Show non-instance aggregate metric to display only the separate instances. Deselect Show only instance name to display the metric group name and instance name in the instance breakdown column.

For example, you can create a view to display CPU usage by selecting the metric CPU:0|Usage. If you add an instance breakdown column, the column CPU:0|Usage displays the usage of all CPU instances on separate rows (0, 1 and so on). To avoid ambiguity, you can change the metric label of CPU:0|Usage to Usage.

The filter option allows you to add additional criteria when the view displays too much information. For example, a list view shows information about the health of virtual machines. From the Filter tab you add a risk metric less than 50%. Then the view will show the health of all virtual machines with risk less than 50%.

To add filter to a view, select Content > Views in the left pane. On the Views toolbar, click the plus sign to add a view or the pencil to edit the selected view. In the workspace, on the left, click Data and click the Filter tab in the main panel. If you create a new view, complete the required previous steps.

Each subject has a separate filter box. For Alerts Rollup, Alert, and Symptom subjects not all applicable metrics are supported for filtering.

Filter Add Options

Option

Description

Add

Adds another criteria to the criteria set. The filter returns results that match all of the specified criteria.

Add another criteria

Adds another criteria set. The filter returns results that match one criteria set or another.

The summary option is available only for List and Summary views. It is mandatory for the Summary views. You can add more than one summary row or column and configure each to show different aggregations. In the summary configuration panel, you select the aggregation method and what data to include or exclude from the calculations.

To add a summary row or column to a view, select Content > Views in the left pane. On the Views toolbar, click the plus sign to add a view or the pencil to edit the selected view. In the workspace, on the left, click Data and click the Summary tab in the main panel. If you create a new view, complete the required previous steps.

For the List view, the summary row shows aggregated information by the specified subjects.

For the Summary view, the summary column shows aggregated information by the items provided on the Data tab.
