If no data is output as a result of data analyses by a variety of operations, a "No data for this period" message is displayed.
For other messages, refer to "17.2 Usage Analysis Function".
Changing the analysis period
When the analysis period is changed, data analysis is performed so that editing results for a number of periods can be displayed. Also, as with the normal analysis page, the analysis period can be changed on the "Summary" window and advanced analysis page.
To change the analysis period, operate "the required period unit from the Unit box", then select "the required period from the Period selection list". When a period is selected from the period selection list, a data analysis is carried out and an analysis page of the edited results is displayed.
Carrying out advanced analysis
Advanced analysis is analysis focusing on a specific URL, clients or error numbers.
To perform an advanced analysis, you select a table line from the analysis page and then from the "Advanced analysis destination" box you select the analysis method of the advanced analysis destination. The advanced analysis is executed and the editing results extracted from the selected items are then displayed.
For example, if you select an arbitrary line from the table in the URL-based analysis page of the session status and select [Breakdown for each client host name] from the "Advanced analysis destination box" an analysis page for each client host name extracted using only the URL name of the line is displayed.
On this page, the total sessions for each client of the specific URLs is displayed.
Advanced analysis can be performed only for analysis pages listed on the "Pages where the advanced analysis can be carried out".
[Window display of the advanced analysis page]
In the analysis information section (above the graph), displayed after an advanced analysis is performed, the name selected from a table is displayed below the analysis type name as the extraction name.
For example, if an advanced analysis is performed from a URL based analysis page, the selected URL name is displayed there.
[Analysis page where the advanced analysis can be carried out]
On analysis pages where the advanced analysis can be performed, the table lines can be selected using the mouse.
On analysis pages of the response status, the lines of a table cannot be selected.
Line selection from a table in the response analysis is intended for graph display switching instead of the advanced analysis. For details, refer to "11.2.5.2 Response analysis page ".
[Operation method]
Display an analysis page where the advanced analysis can be carried out.
Select a line to be subjected to advanced analysis (extracted) from the displayed table.
Click "Advanced analysis destination" and from the drop-down list select the required analysis method for the advanced analysis destination.
An advanced analysis (data analysis) is performed and the data analysis page is updated and displayed. The contents displayed are analysis results (analysis page) based on the line selected from the table.
[Initial window]
The window displayed immediately after the advanced analysis is performed has the following details:
Box | Status |
|---|---|
Analysis target server | Selected server |
Data type | Selected analysis data type |
Analysis method | Analysis method selected from the "Advanced analysis destination box" |
Extraction name | Item name selected from the table line |
Period unit | Same period unit/period as that of the previous analysis page |
Period unit box
The period box is displayed as "xx:yy" units. "xx" indicates the analysis period and "yy" indicates the unit (time axis unit) for plotting on graphs.
For example, if a data analysis is performed as "Week: day" unit, the result is:
Table: The total of results of one week.
Graph: Data for one week is plotted for each day.
Note that the "yy" unit does not apply to the pie chart and "Summary" window. Refer to "Period unit for pie chart and summaries" in the later section.
If the unit of analysis period is selected from the period unit box, the display of the period selection list changes so that a specific analysis period can be selected. No data analysis is executed when you select only the period unit.
Period selection list
In the period selection list, time intervals of the Unit selected on the analysis page are displayed. For example, a 'Week: day unit' setting results in 7-day Sunday-to-Saturday periods being displayed such as "2000/11/7 - 2000/11/13". When a period is selected from the list, a data analysis of the period is performed and the result analysis page is displayed. The analysis type is the same as that of the previous analysis page.
Period units that can be selected and the contents of period selection list when selected
Period unit | Displayed contents of the period selection list | Explanation of format |
|---|---|---|
Year: half-year unit | yyyy | yyyy: year m: month (1 to 12) d: day (1 to 31) |
Year: quarter unit | yyyy | |
Year: month unit | yyyy | |
Half-year: month unit | yyyy/1 - yyyy/6 yyyy/7 - yyyy/12 | |
Quarter: month unit | yyyy/1 - yyyy/3 : yyyy/10 - yyyy/12 | |
Month: day unit | yyyy/m | |
Week: day unit | yyyy/m/d - yyyy/m/d (from Sunday to Saturday) | |
Day: hour unit | yyyy/m/d |
[Operation method]
Click the "Unit" box and select the required unit from the drop-down list.
The period selection list is updated according to the unit selected.
(No data analysis is performed at this step.)
Select a specific period from the period selection list.
Data analysis is performed for the selected period and the analysis page is displayed.
(As other settings on the left side of the page have not been changed, the analysis type is the same as that of the analysis page previously displayed.)
[Period selection list paging]
If the required period is not currently displayed in the period selection list, the list can be scrolled to display the required period.
You scroll the list by clicking the Up button above the list or the Down button below the list.
Click the Up button to scroll to earlier dates. Click the Down button to scroll to later dates.
If the upper limit or lower limit of the display period of the period selection list is reached, each paging button becomes disabled (grayed), as follows:
When the upper limit (any period including 1/1/1980) is displayed, the Up button becomes disabled.
When the lower limit (any period including the current year/month/day) is displayed, the Down button becomes disabled.
[Future period]
No future period can be selected from the period selection list.
Since the current year/month/day is determined based on the client machine time, the client machine time must be correct so that the latest analysis results can be obtained.
For the client machine time, refer also to "11.2.7.1 Date and time".
Period unit for pie chart and summaries
On analysis pages where pie chart is displayed, the total of the selected period is displayed in graphical form.
Thus, editing results are the same for the period units shown below. In addition, a graph totaled for one year is displayed.
Year: half-year unit
Year: quarter unit
Year: month unit
Displaying values for the previous period as graph
Values for the previous period are the comparison reference for graphical analysis. These values are not displayed by default.
By selecting the previous period value box, they can be displayed on the graphs. Previous-period values are always plotted as broken lines, regardless of the graph type.
Three modes are available for the display of pervious-period values depending on the display/calculation methods. The display mode can be selected for each analysis type. The selected display mode is stored for each analysis type while the analysis window is active.
On analysis pages that display a pie chart, previous-period values cannot be displayed.
[Display modes for previous-period values]
The following display types of previous-period values are available. They can be selected on all analysis pages, except for the "Summary" page and "Page Navigation Status" page.
Display mode for previous-period values | Graph display |
|---|---|
Non-display | Previous-period values are not plotted. This is the default state. |
Display | The total for each unit of one period prior to the analysis period is plotted as the previous-period value. For example, if the analysis period is "week: day unit", the total for Monday of last week is plotted for Monday. |
Average value | The total for one period prior to the analysis period divided by the number of units is plotted as the previous-period value. For example, if the analysis period is "week: day unit", the value for the previous period is "total of the previous week/7". |
[Operation method]
Click the "Value of pre-period" box.
Select the required display mode from the drop-down list.
The display of values for the previous period is updated according to the display mode selected.
If data for the previous period is unavailable, values for the previous period are not plotted.
[What is the previous period ?]
