Once per day, HPCA takes a snapshot of the compliance scanning results across your enterprise. Based on this snapshot, an average default score is calculated for each benchmark, version, and profile among the devices to which that profile applies. This information pane shows you the average default score for each benchmark version over time.
Historical Compliance Assessment
If a particular benchmark version contains multiple profiles, an “average of averages” calculation is performed. The average score for all profiles in that benchmark version is calculated.
The vertical axis represents the average default score. The horizontal axis represents time. Each colored line represents a different benchmark and version. The following benchmark versions are displayed in this chart:
The colors are assigned dynamically and are not always the same for a specific benchmark and version. See the legend to see the current color assignments.
When you rest the cursor on one of the colored lines, a tool tip shows you the following information:
To hide a particular line in the chart view, click the corresponding item in the legend. Hidden items are shown in non-bold, italic text in the legend. To show this line again in the chart, click the legend item again.
In the following image, only benchmarks pertinent to Internet Explorer 7 are displayed in the chart:
You can use the sliders to zoom in on a particular region in the data. The sliders determine how much data appears in the chart. The range (scale) of the axis changes to represent only that range selected by the sliders. When you move or click one of the sliders, a tooltip shows you the date or score.
By default, the date range displayed runs from the date of the earliest compliance scanning snapshot to the date of the most recent snapshot. The average score range runs from zero to 100 by default.
When the triangles () are at opposite ends of a slider, the entire data range is visible. When the triangles are closer together, only a subset is visible. You can adjust both triangles on each slider.
If no data appear in the chart, move the triangles to the opposite ends of all three sliders to expose the entire data range.
Note: This pane will not contain data if a fewer than three daily compliance scanning snapshots have been taken—or if no devices have yet been scanned.
If you have just started collecting historical data, you can switch to the grid view to see that data. The grid view for this pane lists the daily average default score for each benchmark version. The table is initially sorted by date, with the most recent snapshot date listed first.
If you narrow down the data range displayed in the chart by using the sliders or by hiding some benchmark versions, the grid view will honor your customizations, and it will only contain the restricted data set.
If you refresh the chart by clicking on the circular arrow icon, the chart is restored to its initial state. The sliders return to the full-range position, all available data is displayed, and all benchmark versions are displayed.
If you click the Launch Report button in this pane, the Historical Compliance Assessment report opens. This report lists all profiles for which there are scan results. The average score for each profile is shown.
