Viewing Trend Reports

The Topaz for Java Trend Reports page is used to view and manage trend reports to understand the Java program performance over a series of measurement time frames. The reports summarize Topaz for Java Performance measurements to help identify trends based on data gathered from measurements. The reports are rendered using the Eclipse-based Business Intelligence and Reporting Tool (BIRT). Information about BIRT can be found at the Eclipse website (http://www.eclipse.org/birt).

The Topaz for Java Trend Reports page shows the following trend reports:

  • Java CPU and Heap Performance: Provides an overview of all samples taken for a given date range.

  • Java CPU and Heap Performance for Time Interval: Provides an overview of all samples taken for a given date range but further specifies a particular clock time period for those days within the date range.

To access the Trend Reports page

From the Topaz for Java Performance landing page, do one of the following:

  • Click .

  • Click and then select Trend Reports.

The Topaz for Java Trend Reports page appears, showing the following reports for the measurements that have been run:

  • Java CPU and Heap Performance

  • Java CPU and Heap Performance for Time Interval

To specify a data range

From the Date range list, select a date range or click in the From or To boxes and modify the dates to create a custom range.

To specify a time range

Note: This functionality applies to the Java CPU and Heap Performance for Time Interval report.

From the Time range boxes, select a time by clicking the time and specifying the hour or minute. Use the directional arrows in the box to move between hours and minutes. Click the button in the center of the directional arrows to automatically select the current time.

To use filtering on the Topaz for Java Trend Reports page
