How the Metric Chart Widget and Configuration Options Work

You can add the Metric Chart widget to one or more custom dashboards and configure it to display the workload for your objects. The data that appears in the widget is based on the configured menu items for each widget instance.

You edit the Metric Chart widget after you add it to a dashboard. The changes you make to the menu items create a custom widget with the selected metrics that display the workload on your objects.

To select metrics, you can select an object from the object list, then select the metrics. Or, you can select a tag from the object tag list to limit the object list, then select an object. You can configure multiple charts for the same object or multiple charts for different objects.

To use the metric configuration, which displays a set of metrics that you defined in an XML file, the dashboard and widget configuration must meet the following criteria:

The dashboard

Widget Interaction

menu items are configured so that another widget provides objects to the target widget. For example, an Object List widget provides the object interaction to a chart widget.

The widget

Self Provider

options are set to

Off

.

The custom XML file in the

Metric Configuration

drop-down menu is in the

/usr/lib/vmware-vcops/tools/opscli

directory and has been imported into the global storage using the import command.

Metric Chart Widget Toolbar Options

On the title bar of the widget, click the

Show Toolbar

icon to access the toolbar options.

The toolbar contains icons that you can use to change the view of the graphs.

Option	Description
Split Charts	Displays each metric in a separate chart.
Stacked Chart	Consolidates all charts into one chart. This chart is useful for seeing how the total or sum of the metric values vary over time. To view the stacked chart, ensure that the split chart option is turned off.
Dynamic Thresholds	Shows or hides the calculated dynamic threshold values for a 24-hour period.
Show Entire Period Dynamic Thresholds	Shows or hides dynamic thresholds for the entire time period of the graph.
Static Thresholds	Shows or hides the threshold values that have been set for a single metric.
Anomalies	Shows or hides anomalies. Time periods when the metric violates a threshold are shaded. Anomalies are generated when a metric crosses a dynamic or static threshold, either above or below.
Trend Line	Shows or hides the line and data points that represents the metric trend. The trend line filters out metric noise along the timeline by plotting each data point relative to the average of its adjoining data points.
Show Data Values	Activates the data point tooltips if you switched to a zoom or pan option. Show Data Point Tips must be activated.
Zoom All Charts	Resizes all the charts that are open in the chart pane based on the area captured when you use the range selector. You can switch between this option and Zoom the View .
Zoom the View	Resizes the current chart when you use the range selector.
Pan	When you are in zoom mode, allows you to drag the enlarged section of the chart so that you can view higher or lower, earlier or later values for the metric.
Zoom to Fit	Resets the chart to fit in the available space.
Remove All	Removes all the charts from the chart pane, allowing to you begin constructing a new set of charts.
Refresh Charts	Reloads the charts with current data.
Date Controls	Opens the date selector. Use the date selector to limit the data that appears in each chart to the time period you are examining. Select Dashboard Time to activate the dashboard time panel. The option chosen in the dashboard time panel is effective. The default time is 6 hours. Dashboard Time is the default option.
Generate Dashboard	Saves the current charts as a dashboard.
Save as PDF	Saves the current metric chart as a PDF file. If you have added many metrics for different objects to a metric chart, you can quickly download and share the PDF file with another user or VM owner. You can create ad-hoc reports when analyzing metrics. You can also add notes to the metrics to provide context to the user.

Metric Chart Widget Graph Selector Options

The graph selector options determine how individual data appears in the graph.

Option	Description
Close	Deletes the chart.
Save a snapshot	Creates a PNG file of the current chart. The image is the size that appears on your screen. You can retrieve the file in your browser's download folder.
Download comma-separated data	Creates a CSV file that includes the data in the current chart. You can retrieve the file in your browser's download folder.
Save a full screen snapshot	Downloads the current graph image as a full-page PNG file, which you can display or save. You can retrieve the file in your browser's download folder.
Units	You can display the data with dots or as a percentage.
Thresholds	You can choose to show/hide Critical , Immediate , and Warning thresholds in the current chart.
Scales	You can choose a scale for a stacked chart. Select Linear to view a chart in which the Y axis scale increases in a linear manner. For example, the Y axis can have ranges from 0 to 100, 100 to 200, 200 to 300, and so on. Select Logarithmic to view a chart in which the Y axis scale increases in a logarithmic manner. For example, the Y axis can have ranges from 10 to 20, 20 to 300, 300 to 4000, and so on. This scale gives a better visibility of minimum and maximum values in the chart when you have a large range of metric values. If you select a logarithmic scale, the chart does not display data points for metric values less than or equal to 0, which leads to gaps in the graph. Select Combined to view overlapping graphs for the metrics. The chart uses individual scales for each graph instead of using a relative scale, and displays a combined view of the graphs. Select Combined by Unit to view a chart that groups the graphs for similar metric units together. The chart uses a common scale for the combined graphs.
Move Down	Moves the chart down one position.
Move Up	Moves the chart up one position.

You can take the following actions on the Metric Chart graph.

Option	Description
Y Axis	Shows or hides the Y-axis scale.
Chart	Shows or hides the line that connects the data points on the chart.
Data Point Tips	Shows or hides the data point tooltips when you hover the mouse over a data point in the chart.
Zoom by X	Enlarges the selected area on the X axis when you use the range selector in the chart to select a subset of the chart. You can use Zoom by X and Zoom by Y simultaneously.
Zoom by Y	Enlarges the selected area on the Y axis when you use the range selector in the chart to select a subset of the chart. You can use Zoom by X and Zoom by Y simultaneously.
Zoom by Dynamic Thresholds	Resizes the Y axis of the chart so that the highest and the lowest values on the axis are the highest and the lowest values of the dynamic threshold calculated for this metric.
Vertical resize	Resizes the height of a graph in the chart.
Remove icon next to each metric name in a stacked chart	Removes the graph for the metric from the chart.

If the objects have an input transformation applied, you define filter criteria for the object types of the transformed objects. In the first drop-down menu, select an object type. 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 .
