Performance counters are CPU hardware registers that count hardware events such as instructions executed, cache-misses suffered, or branches mispredicted. They form a basis for profiling applications to trace dynamic control flow and identify hotspots. Linux perf interface provides rich generalized abstractions over hardware specific capabilities. The intel_pmu plugin collects performance counters data on Intel CPUs using Linux perf interface. All events are reported on a per core basis. For a full description of available options please refer to the collectd.conf(5) manual page.
