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。

主机部署Kubernetes

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

字段类型: Duration

采集器配置字段: interval

默认值: 10s
ENV_INPUT_CPU_PERCPU

采集每一个 CPU 核

字段类型: Boolean

采集器配置字段: percpu

默认值: false
ENV_INPUT_CPU_ENABLE_TEMPERATURE

采集 CPU 温度

字段类型: Boolean

采集器配置字段: enable_temperature

默认值: true
ENV_INPUT_CPU_ENABLE_LOAD5S

每五秒钟获取一次平均负载信息

字段类型: Boolean

采集器配置字段: enable_load5s

默认值: 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

字段类型: String

采集器配置字段: tags

示例: 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"
  # ...

`cpu`¶

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
core_temperature	CPU core temperature. This is collected by default. Only collect the average temperature of all cores. Type: float Unit: temperature,C
load5s	CPU average load in 5 seconds. Type: int Unit: -
usage_guest	% CPU spent running a virtual CPU for guest operating systems. Linux only Type: float Unit: percent,percent
usage_guest_nice	% CPU spent running a nice guest(virtual CPU for guest operating systems). Linux only(>=3.2.0) Type: float Unit: percent,percent
usage_idle	% CPU in the idle task. Type: float Unit: percent,percent
usage_iowait	% CPU waiting for I/O to complete. Linux only Type: float Unit: percent,percent
usage_irq	% CPU servicing hardware interrupts. Type: float Unit: percent,percent
usage_nice	% CPU in user mode with low priority (nice). Linux only Type: float Unit: percent,percent
usage_softirq	% CPU servicing soft interrupts. Linux only Type: float Unit: percent,percent
usage_steal	% CPU spent in other operating systems when running in a virtualized environment. Linux only Type: float Unit: percent,percent
usage_system	% CPU in system mode. Type: float Unit: percent,percent
usage_total	% CPU in total active usage, as well as (100 - usage_idle). Type: float Unit: percent,percent
usage_user	% CPU in user mode. Type: float Unit: percent,percent
