Sparkline Chart Widget

The Sparkline Chart widget displays graphs that contain metrics for an object in vRealize Operations. You can use vRealize Operations to create one or more graphs that contain metrics for objects that you add to your custom dashboards.

How the Sparkline Chart Widget and Configurations Options Work

If the metrics in the Sparkline Chart are for an object that another widget provides, the object name appears at the top right of the widget. If you select a metric when you edit the widget configuration, the widget uses the metric and its corresponding object as the source for dashboard interactions. The line in the graphs represents the average value of the selected metric for the specified time period. The boxed area in the graph represents the dynamic threshold of the metric.

Point to a graph in the Sparkline Chart widget to view the value of a metric in the form of a tool tip. You can also view the maximum and minimum values on a graph. The values are displayed as orange dots.

You can add the Sparkline Chart widget to one or more custom dashboards and configure it to display data that is important to different dashboard users. The data that appears in the widget is based on the configured options for each widget instance.

The metrics shown in sparkline widget is the current value, to view the average value you can use transformations in list views or distribution charts to calculate an average. Another way to get to an average value is to double click on the sparkline to open the metric chart, click and drag to select a range, keep the mouse button depressed and hover for a few seconds, you should see a popup that has average value.

Input Data
Metrics	Select metrics on which you want to base the widget data. You can select an object and pick its metrics. Click the Add New Metrics icon to add metrics for the widget data. Select an object to view its metric tree and pick metrics for the object. The picked metrics appear in a list in this section. The metric tree shows common metrics for several objects when you click the Show common metrics icon. While selecting objects for which you want to pick metrics, you can use the Filter text box to search for objects. You can also expand the Tag Filter pane on the left hand side to select one or more object tag values. A list of objects with the selected tag values appears. If you select more than one value for the same tag, you can choose objects that have any of the tags applied. If you select more than one value for different tags, you can choose only the objects that have all the tags applied. Optionally, select metrics from the list and click the Remove Selected Metrics icon to remove the selected metrics. Click the Select All icon to select all the metrics in the list. Click the Clear Selection icon to clear your selection of metrics in the list. Optionally, you can customize a metric and apply the customization to other metrics in the list. Double-click a metric box in the list to customize the metric and click Update. You can use the Box Label text box to customize the label of a metric box. You can use the Unit text box to define a measurement unit of each metric. You can use the Color Method option to define a coloring criteria for each metric. If this option is set to Custom, you can enter color values in the Yellow, Orange, and Red text boxes. You can also set coloring by symptom definition. If you do not want to use color, select None. For example, to view the remaining memory capacity of a VM, select Virtual Machine as an object type, expand the Memory from the metric tree and double-click Capacity Remaining(%). Define a meaningful label name and measurement unit to help you when you observe the metrics. You can select Custom from the Color Method drop-down menu and specify different values for each color, for example 50 for Yellow, 20 for Orange, and 10 for Red. Select a metric and click the Apply to All icon to apply the customization for the selected metric to all the metrics in the list.

In the second drop-down menu, select the option based on which you want to define the filter criteria. For example, if you select Metrics for the Datacenter object type, you can define a filter criteria based on the value of a specific metric for data centers. In the drop-down menus and text boxes that appear, select or enter values to filter the objects. To add more filter criteria, click Add. To add another filter criteria set, click Add another criteria set.
