Analyzing transaction file usage

You can analyze the file usage for one or more Transaction IDs and display the output as a pie chart, a bar chart, or a timeline chart.

Pie charts

Pie charts are displayed in the Transaction detail view and show detailed information about a single transaction ID.

To display a Transaction detail view, see the Pie charts section in the Analyzing data topic.

The following screen capture shows the Transaction detail view with the File usage pie chart selected, and showing detailed file request information for the selected Transaction ID.

The file analysis pie chart displays the following information:
  • A section title, containing the type of analysis and the name of the transaction being analyzed.
  • A pie chart consisting of a number of sectors, one for each type of file request.
  • A table containing the file request total count average, and a breakdown of the requests. When you click a sector in the pie chart, the relevant entry in the table is highlighted.

By selecting one or more of the check boxes in the view you can choose to hide irrelevant data from the table.

Note: The values displayed in the table are the actual values from the CSV file. Because of rounding errors when the data was captured, the sum of the detail might not match the total value. In addition, the percentage figures might not total 100% because of rounding errors.

Bar charts

Bar charts show summary information for multiple Transaction IDs. The Transaction IDs are displayed in the order in which they are shown in the selection.

To display a File usage bar chart, see the Bar charts section in the Analyzing data topic.

The following screen capture shows a File usage bar chart view containing six different transaction IDs.

The chart displays the following information:
  • A view title, containing the name of the analysis; in this case, File usage.
  • An information bar in the view, containing the name of the source file that contains the data.
  • A stacked bar for each Transaction ID selected. Each bar in a stack consists of one or more sectors, each representing a different file request. You can hover over a sector to show the type and count average for each file request.
  • A Legend icon The legend icon in the chart. Click this icon to display the chart legend.

You can use the zoom bar in the chart to change the time scale on the Y-axis to show more detail.

You can perform further analysis on a single Transaction ID by selecting a stacked bar, right-clicking, and clicking Performance history > Detail breakdown in the pop-up menu. The new information displays as a pie chart in the Transaction detail view.

Alternatively, you can select multiple transaction IDs using the Shift or Ctrl keys. Right-click the selection and click one of the options in the pop-up menu.

Timeline charts

Timeline charts show all instances of a Transaction ID in the selected application ID across the whole data file, or a range of dates specified using the Date dialog when selecting the data.

To display a File usage timeline chart, see the Timeline charts section in the Analyzing data topic.

The chart displays the following information:
  • A view title, containing the name of the analysis; in this case, File usage.
  • An information bar in the view, containing the path and name of the CSV or database file that contains the data.
  • A stacked bar for each Transaction ID selected. Each bar in a stack consists of one or more sectors, each representing a different file request. You can hover over a sector to show the type and count average for each file request.
  • A Legend icon The legend icon in the chart. Click this icon to display the chart legend.

You can use the zoom bar in the chart to change the time scale on the Y-axis to show more detail.

You can perform further analysis on a single Transaction ID by selecting a stacked bar, right-clicking, and clicking Performance history > Detail breakdown in the pop-up menu. The new information displays as a pie chart in the Transaction detail view.

Alternatively, you can select multiple Transaction IDs using the Shift or Ctrl keys. Right-click the selection and click one of the options in the pop-up menu.

The performance history works primarily from the performance summary rather than statistics tables. However, you can access performance history records from the Reports view or other perspectives (for example CICS® IA).
