Adding new events to the Events to Collect list
Streamline uses the list of counters in the Events to Collect list to determine what data to collect during a capture session. If an event you want does not appear on the list, you can add it using the Counter Configuration dialog box.
To add events to the list:
- Open the Counter Configuration dialog box using the button in the Streamline Data view.
Double-click on an event, or select and drag events from the Available Events list and drop them in the
Events to Collect area.
The added events appear in the Events to Collect list under their category name.
The more counters that you select, the greater the probe effect is.
Streamline generates charts for all counters in the Events to Collect list. These are called auto-generated charts. Sticky Snippets are customized charts that the user has chosen to be displayed in the Live and Timeline views in every new capture or report. If the same counters are used by both an auto-generated chart and a Sticky Snippet, then the Sticky Snippet is displayed in the view rather than the auto-generated chart.
In cases where a counter can be collected on one of a number of different
cores or interfaces, a drop-down menu appears next to the counter in the
Events to Collect list. Use this menu to select a
specific core or interface.
For example, the ARM® Versatile™ Express TC2 hardware, featuring CCI-400 coherent interconnect, enables you to collect counters over a number of different interfaces. The interface drop-down menu in the Events to Collect list is specific to this hardware.
