Counter Configuration dialog box structure

The Counter Configuration dialog box contains two main areas, Available Events and Events to Collect. Select counters in the Available Events list to populate the Events to Collect list.

Counter Configuration dialog box

The dialog box contains the following areas:

Available Events

The Available Events list contains categorized events offered for each core on your target, as well as a list of other hardware and OS-specific events. The events contained in the processor lists are based on the PMU counters of the core, so can vary depending on the type of processor, as can the number of events that you can add. Events that are already in the Events to Collect list appear in gray.


Streamline supports hwmon counters, for example temperature and energy consumption, if they are available on your target hardware.

The maximum number of available events and the amount remaining are shown in the upper right hand corner of the header for each category section in the Available Events list. When you have reached the maximum, all entries in the category list are grayed out and you cannot add any more events to the Events to Collect list.


If problems occurred during gator setup, for example if the target is running a version of gator that does not support some counters, a warnings tag is displayed beside the filter field.
Events to Collect

This list of categories and events is used by the Timeline view for its graphs. Each event listed here is available for display in a chart in the Timeline view.

Event Based Sampling

This field is active only if an event in the Events to Collect list has event-based sampling turned on. In this case, the Threshold value indicates the number of times the event must be triggered in order for Streamline to sample it.
