CPU

CPU 采集器用于系统 CPU 使用率的采集。

配置

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.
  ##
  # disable_temperature_collect = false
  enable_temperature = true
  ##
  enable_load5s = true
  ##
  [inputs.cpu.tags]
    # some_tag = "some_value"
    # more_tag = "some_other_value"

配置好后，重启 DataKit 即可。

Kubernetes 中支持以环境变量的方式修改配置参数：

环境变量名 对应的配置参数项 参数示例
ENV_INPUT_CPU_PERCPU percpu true/false
ENV_INPUT_CPU_ENABLE_TEMPERATURE enable_temperature true/false
ENV_INPUT_CPU_TAGS tags tag1=value1,tag2=value2 如果配置文件中有同名 tag，会覆盖它
ENV_INPUT_CPU_INTERVAL interval 10s
ENV_INPUT_CPU_DISABLE_TEMPERATURE_COLLECT disable_temperature_collect false/true。给任意字符串就认为是 true，没定义就是 false。
ENV_INPUT_CPU_ENABLE_LOAD5S enable_load5s false/true。给任意字符串就认为是。给任意字符串就认为是 true，没定义就是 false。

指标集

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"
  # ...
