System core metricset

The System core metricset provides usage statistics for each CPU core.

This metricset is available on:

  • FreeBSD
  • Linux
  • macOS
  • OpenBSD
  • Windows

Configuration

core.metrics
This option controls what metrics are reported for each CPU core. The value is a list and two metric types are supported - percentages and ticks. The default value is core.metrics: [percentages].
use_performance_counters

This option enables the use of performance counters to collect data for the CPU/core metricset. It is only effective on Windows. You should use this option if running beats on machins with more than 64 cores. The default value is use_performance_counters: true

metricbeat.modules:
- module: system
  metricsets: [core]
  core.metrics: [percentages, ticks]
  #use_performance_counters: false
