Working with Charts

Data charting enables you to create pre-defined and customizable charts that let you access and analyze collected data.

This section describes the options available when you are adding charts to a dashboard or report that you have created.

Creating a Metrics Chart

To create a metrics chart:

1 Drag each metric from the Data tab in the action panel into its own chart, as shown below.

Figure 17

• The metrics in the chart are indicated by different-colored lines at the left side of the chart under count and percentage (%).

• The line for the currently displayed metric (by default, the first one chosen) is bold. To highlight other metrics in the chart, click on the lines in the legend.

The legend below the chart changes to indicate the name of the highlighted metric.

• When you hover over a line in the chart, a dwell indicates the name of the metric, as well as the count or percentage and the specific date and time when it was collected.

User Guide

The Y axis shows the units for the metric. If there is more than one metric in the chart, the Y axis shows the units for the first metric that was charted, unless you have

unchecked the Layout check box in the Metric Chart Default dialog (see “ Setting Metric

Chart Labels ” on page 88 for details).

By using the Customizer function you have the option to export metric data for charts to

CSV format. See “ Exporting Data from Charts and Tables ” on page 57.

Zooming Into Charts

For plot or bar charts, you can zoom into an area to view data at different levels of detail by using CTRL + drag. You can also drag on an axis to specify the region you would like to zoom into (a zoom region).

To zoom into a chart:

1 In a line graph, zoom in to the area of the chart. Select one of the following methods to specify a zoom region:

• press CTRL + drag on the area

• drag on the axes of the chart

2 The chart will zoom into the range selected and will locally change the time range so vFoglight displays all data points. Now you can view the data for the selected metric at a more granular level.

3 To zoom out and return the line chart to its original view, click the Reset Zoom icon in the top right corner.

Changing the Chart Type

If the Customizer icon is enabled for charts, you have the option to dynamically change the chart to a different chart type (bar, plot, area, stacking area). For example, choose the chart type to Area to emphasize the magnitude of change over time and illustrate the metric parts in relation to the whole graph.

Note To access the customizer it needs to be enabled. By default, chart customizers are not enabled.

To change the chart type:

2

Click the Customizer icon in the top right hand corner of the chart.

In the Chart Type dialog box, click the chart type to change.

The chart dynamically changes to the selected chart type.

Show Thresholds If a metric has a threshold, it is displayed.

You can choose to show thresholds only for the selected metric.

Grouping Metrics with Many Parent Hosts

When you have many metrics on a chart from different parent hosts, the parent label will appear in the legend when metrics are grouped. For example, in the chart on the left below, if you drag metrics from a Windows_Host and from a Windows_CPU, the parent label shows up in the metric labels themselves since the metrics are mixed. In the chart on the right below, if you drag metrics from the Windows_CPU host only, the legend does not refer to the parent.
