12.6 Customizing Default Performance Chart Settings

Various properties can be set in the applet_params.xml to customize default chart settings such as suppressing end data point display, filling in time line holes as needed and setting the maximum outstanding requests to retrieve performance data.

To set custom properties for native performance data:

  1. In a text editor, open the /OperationsCenter_install_path/html/applet_params.xml file.

  2. Do any of the following:

    • To extend the last data point until the end of the time line window in numeric charts (not condition charts), add the following line:

      <param name="BSAChartPanel.extendLastDataPoint" value="true" />
    • To control whether native performance data extends to the end of the chart time line by replicating the last data point AND fill time line holes as needed, add the following line :

      <param name="BSAChartPanel.nativePerformanceExtendAndFillHoles" value="true" />

      This setting overrides any value as set for the BSAChartPanel.extendLastDataPoint property above.

    • To override the maximum number of requests queued per chart to retrieve performance data as the chart time line is adjusted and drawn, add the following line and specify the desired maximum number of requests to queue:

      <param name="BSAChartPanel.requestQueueMaxSize" value="Max" />

      The system default is 4 outstanding requests. We recommend keeping the value low. Specifying zero or lower makes the performance data request queue unbounded.

  3. Save the file.
