From the Features page, the Usage History tab shows statistics for license usage during any period that usage was tracked. In addition, you can see monthly percentage of use under the Utilization History tab. The settings you make on this page (for example, filters) are retained for the next time you log into License Statistics.

To choose the feature for which to view statistics, use the License Server and Feature pick lists in the Select License Server and Feature section at the top of the page. You can select either an individual license server or a license server group from the License Servers pick list. After selecting the license server/license server group, the Feature pick list will then contain all features within that license server/license server group for you to choose from. To compare multiple usage history reports, see Usage History Comparison report.

General Information

The General Information area includes identifying information for the feature, the last update time, a share code if sharing is in use (for example, "Shared on: HOST"), and the license type.

Advanced Filtering

The Advanced Filtering area lets you filter the information that displays in the Feature Usage History grid and graph by specified intervals. Using the pick lists in the Advanced Filtering area, you can choose to show results in the Feature Usage History grid by the following intervals and selecting the desired dates from the Date range calendar: 

• Yearly (may be grouped by quarter, month, week, day, or hour)
• Quarterly (may be grouped by month, week, day, or hour)
• Monthly (may be grouped by week, day, or hour)
• Weekly (may be grouped by day or hour)
• Daily
• Custom (lets you select the start date and end date for which to view statistic and may be grouped by quarter, month, week, day, or hour)

 For example, if you choose to group results by quarters in a selected year, your results will look similar to the following:

The Advanced Filtering area also lets you choose whether to show used, borrowed and total licenses on the graph. For more information about graphs, see Feature usage graphs. 

Average usage calculation 

The average usage (Avg Used column value) is computed differently depending on how the usage history data is grouped. 

• When data is grouped by Day, the average usage is the weighted average of licenses used in particular day. For example, if you use 1 license for 8 minutes, then use 6 licenses for 2 minutes, the average usage is calculated as (1*8 + 6*2) / (2+8) = 2.
• When data is grouped by Week, the value displayed is the mathematical average of the weighted averages.

Feature Usage History grid

The Feature Usage History grid includes both the number and percentage of minimum, average, and maximum license usage and minimum and maximum borrowed licenses. The grid also includes the total number of licenses for the selected feature, the number of hours at least one license for a particular feature was used and/or borrowed, as well as information about denials. 

The color of the text in the license usage columns helps you quickly recognize the level of utilization:

1. Red: 90% - 100% utilization
2. Yellow: 70% to 89% utilization
3. Green: 0% to 69% utilization

Note that if you filter the grid data using the grid columns, those filters will also be used in the graph and when downloading the data to a file. For more information, see Introduction to using License Statistics pages and User preferences. 

Feature Usage History graph

The Feature Usage History graph plots the number of licenses used, giving you a quick picture of license usage fluctuation during the selected time period. The graph reflects the advanced filters, certain grid filters, and the number of rows you select to display in the grid. For example, if you filter the Min Borrowed column to show only values greater than 1 and limit the number of rows displayed to 20, the graph results will also be limited to Min Borrowed values greater than 1 and the 20 rows of data.

Note: When the Feature Usage History graph is hidden, License Statistics does not have to push the high volume of data that is normally loaded into the chart. Therefore, hiding the display of this graph increases the performance of License Statistics, causing it to run faster.
