Analyzing the performance summary by using charts
You can use the CICS® PA plug-in for CICS response time, user CPU time, threadsafe, storage usage, and file request activity analysis. You can view the data selected for analysis as pie charts, bar charts, or timeline charts. You can also view the properties and values of a transaction ID.
Before you begin, check that the analysis that you want is available. By default, all charts are available, but you can set CICS PA plug-in preferences to disable specific categories of analysis and restrict the associated charts. If the analysis you require is not available, check the Categorization enablement preferences. See CICS Performance Analyzer Preferences.
Pie charts
Pie charts are displayed in the Transaction detail view. The pie charts show a detailed breakdown of a single transaction ID in the time period selected.
To display the Transaction detail view, right-click a transaction summary record in the Sheet view, then click Performance summary. Click on a pie chart thumbnail to view a full sized pie chart and its associated details. For more information about this view, see Transaction detail view.

Bar charts

- Right-click a selected record, click Transaction performance,
then click the required analysis type from the following options:
- CICS Response time
- User CPU time
- Threadsafe
- Storage usage
- File Request activity
A bar chart for the selected analysis, with a bar for
each selected transaction, is displayed in a new view. Depending on
the type of analysis, a bar might have more than one segment. Click
the Legend icon to display the segment descriptions.
The following example screen capture shows a CICS response time analysis.

- The view title shows the source of the data and the analysis type.
- The information line shows the selection criteria for the data the records were selected from, for example, APPLID and time period.
- Legend icon
. Click this icon to display the chart legend for the segments in the current chart.
- A stack of bars for each selected transaction ID. Each bar in a stack has one or more segments to represent different fields for the transaction ID. You can hover over a segment to show further information about the field.
To change the time scale on the vertical axis of the chart and show more detail, you can use the zoom bar.
To analyze a transaction ID further, right-click a bar, then use the menu options to select a performance summary (pie chart) or timeline analysis.
For more information about bar chart details for a specific analysis type, see the related links at the end of this information.
Timeline charts
A timeline chart displays all instances of a transaction ID in the selected APPLID across either all the data, or the data in a specified period. To display a timeline chart, use the following procedure:
- To restrict the analysis to a specific period, click the Performance
