This subtab shows a historical table of the data usage in the DME system, by month. Note that the date filter does not apply in this subtab. You can sort the table by clicking the table headers. The statistics show the following (by column):
The year and number of the month for which the data are shown.
The totals line shows the total number of months for which statistics are shown.
This column shows the number of data requests made by devices within the month in question. A request could be one act of synchronization, or an application download (client upgrade). Next to the actual number of requests is a graph showing that particular month's share of the overall number of requests made to the server. If you let the mouse pointer rest on the colored part of the graph, a tooltip text will reveal the month's share of the total requests made as a percentage.
The totals line shows the total number of requests made to the server.
This column shows the amount of DME data transferred within the month in question. After the actual number, a graph shows the month's share in the overall DME data traffic. The graph is filled with two shades of blue: A dark blue (the left-hand end) showing the percentage of Incoming data (for instance calendar entries created on the device and synchronized to the server), and a lighter blue showing the percentage of Outgoing data (synchronized or downloaded to the device). If you let the mouse pointer rest on either color, a tooltip text will reveal the actual percentage.
The hatched area (
) of the graphs shows the standard deviation and the mean (the solid blue line) of the total set of data.
The totals line shows the total amount of data moved.
This column shows the average amount of DME data transferred within the month in question - that is, the average amount of data per request. The percentage number in parentheses indicates the month's average request size in relation to the total average shown in the totals line.
The first number in the totals line shows the total amount of data (the Data column) divided by the total number of months (the Month column), resulting in the average amount of data moved per month. The second number shows the total number of requests (the Requests column) divided by the total amount of data, resulting in the average request size.
