CPU

CPU 采集器用于系统 CPU 使用率等指标的采集。

配置

采集器配置

成功安装 DataKit 并启动后，会默认开启 CPU 采集器，无需手动开启。

进入 DataKit 安装目录下的 conf.d/host 目录，复制 cpu.conf.sample 并命名为 cpu.conf。示例如下：

[[inputs.cpu]]
  ## Collect interval, default is 10 seconds. (optional)
  interval = '10s'

  ## Collect CPU usage per core, default is false. (optional)
  percpu = false

  ## Setting disable_temperature_collect to false will collect cpu temperature stats for linux. (deprecated)
  # disable_temperature_collect = false

  ## Enable to collect core temperature data.
  enable_temperature = true

  ## Enable gets average load information every five seconds.
  enable_load5s = true

[inputs.cpu.tags]
  # some_tag = "some_value"
  # more_tag = "some_other_value"

配置好后，重启 DataKit 即可。

可通过 ConfigMap 方式注入采集器配置 或 配置 ENV_DATAKIT_INPUTS 开启采集器。

也支持以环境变量的方式修改配置参数（需要在 ENV_DEFAULT_ENABLED_INPUTS 中加为默认采集器）：

  • ENV_INPUT_CPU_INTERVAL

    采集器重复间隔时长

    Type: TimeDuration

    ConfField: interval

    Default: 10s

  • ENV_INPUT_CPU_PERCPU

    采集每一个 cpu 核

    Type: Boolean

    ConfField: percpu

    Default: false

  • ENV_INPUT_CPU_ENABLE_TEMPERATURE

    采集 cpu 温度

    Type: Boolean

    ConfField: enable_temperature

    Default: true

  • ENV_INPUT_CPU_ENABLE_LOAD5S

    每五秒钟获取一次平均负载信息

    Type: Boolean

    ConfField: enable_load5s

    Default: false

  • ENV_INPUT_CPU_TAGS

    自定义标签。如果配置文件有同名标签，将会覆盖它

    Type: Map

    ConfField: tags

    Example: tag1=value1,tag2=value2

指标

以下所有数据采集，默认会追加名为 host 的全局 tag（tag 值为 DataKit 所在主机名），也可以在配置中通过 [inputs.cpu.tags] 指定其它标签：

 [inputs.cpu.tags]
  # some_tag = "some_value"
  # more_tag = "some_other_value"
  # ...

  • 标签
Tag Description
cpu CPU core ID. For cpu-total, it means all-CPUs-in-one-tag. If you want every CPU's metric, please enable percpu option in cpu.conf or set ENV_INPUT_CPU_PERCPU under K8s
host System hostname.
  • 指标列表
Metric Description Type Unit
core_temperature CPU core temperature. This is collected by default. Only collect the average temperature of all cores. float C
load5s CPU average load in 5 seconds. int -
usage_guest % CPU spent running a virtual CPU for guest operating systems. float percent
usage_guest_nice % CPU spent running a nice guest(virtual CPU for guest operating systems). float percent
usage_idle % CPU in the idle task. float percent
usage_iowait % CPU waiting for I/O to complete. float percent
usage_irq % CPU servicing hardware interrupts. float percent
usage_nice % CPU in user mode with low priority (nice). float percent
usage_softirq % CPU servicing soft interrupts. float percent
usage_steal % CPU spent in other operating systems when running in a virtualized environment. float percent
usage_system % CPU in system mode. float percent
usage_total % CPU in total active usage, as well as (100 - usage_idle). float percent
usage_user % CPU in user mode. float percent
