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.

Figure 4-2 The Counter Configuration dialog box

The 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 current target as well as a list of other hardware and OS-specific events. The events contained in the processor lists depend on the type of processor as does the number of events that you can add. Events that appear in gray are already in the Events to Collect list.

Note

Streamline supports hwmon counters, 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.

Note

The events that appear in this list are based on the PMU counters of the core.
Events to Collect

This list of categories and events is what the Timeline view uses for its graphs. Each event listed here is available for display in the Timeline view using the Chart Configuration 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.
