CPU Input Plugin

The cpu plugin gather metrics on the system CPUs.

macOS Support

The gopsutil library, which is used to collect CPU data, does not support gathering CPU metrics without CGO on macOS. The user will see a "not implemented" message in this case. Builds provided by InfluxData do not build with CGO.

Users can use the builds provided by Homebrew, which build with CGO, to produce CPU metrics.

Configuration

# Read metrics about cpu usage
[[inputs.cpu]]
  ## Whether to report per-cpu stats or not
  percpu = true
  ## Whether to report total system cpu stats or not
  totalcpu = true
  ## If true, collect raw CPU time metrics
  collect_cpu_time = false
  ## If true, compute and report the sum of all non-idle CPU states
  report_active = false
  ## If true and the info is available then add core_id and physical_id tags
  core_tags = false

Metrics

On Linux, consult man proc for details on the meanings of these values.

• cpu
  • tags:
    • cpu (CPU ID or cpu-total)
  • fields:
    • time_user (float)
    • time_system (float)
    • time_idle (float)
    • time_active (float)
    • time_nice (float)
    • time_iowait (float)
    • time_irq (float)
    • time_softirq (float)
    • time_steal (float)
    • time_guest (float)
    • time_guest_nice (float)
    • usage_user (float, percent)
    • usage_system (float, percent)
    • usage_idle (float, percent)
    • usage_active (float)
    • usage_nice (float, percent)
    • usage_iowait (float, percent)
    • usage_irq (float, percent)
    • usage_softirq (float, percent)
    • usage_steal (float, percent)
    • usage_guest (float, percent)
    • usage_guest_nice (float, percent)

Troubleshooting

On Linux systems the /proc/stat file is used to gather CPU times. Percentages are based on the last 2 samples. Tags core_id and physical_id are read from /proc/cpuinfo on Linux systems
