This has certain adventages when application runs on\nisolated cores with nohz_full kernel parameter.\n\nEvents can be read directly using rte_pmu_read() or using dedicated\ntracepoint rte_eal_trace_pmu_read(). The latter will cause events to be\nstored inside CTF file.\n\nBy design, all enabled events are grouped together and the same group\nis attached to lcores that use self monitoring funtionality.\n\nEvents are enabled by names, which need to be read from standard\nlocation under sysfs i.e\n\n/sys/bus/event_source/devices/PMU/events\n\nwhere PMU is a core pmu i.e one measuring cpu events.
