Perf metrics

The Perf metrics use the Linux kernel perf_event_open() system call to provide additional CPU related metrics available for Linaro Performance Reports.

They can be used on any system supported by the Linux perf command (also called perf_event). These cannot be tracked on typical virtual machines.

Linaro Performance Reports generally requires no extra configuration for Perf metrics before use. For more information about Perf metrics, and specific settings for generating Perf metrics in the reports, see Configurable Perf metrics.
