DataKit 自身指标采集

· Version-1.11.0


Datakit 采集器用于自身基本信息的采集,包括运行环境信息、CPU、内存占用、各个核心模块指标等。

配置

Datakit 启动后。默认会暴露一些 Prometheus 指标,没有额外的操作需要执行,本采集器也是默认启动的,替代了之前的 self 采集器。

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

[[inputs.dk]]

  # See https://docs.guance.com/datakit/datakit-metrics/#metrics for all metrics exported by Datakit.
  metric_name_filter = [
    ### Collect all metrics(these may collect 300+ metrics of Datakit)
    ### if you want to collect all, make this rule the first in the list.
    # ".*",

    "datakit_http.*",       # HTTP API
    "datakit_goroutine.*",  # Goroutine

    ### runtime related
    "datakit_cpu_.*",
    "datakit_.*_alloc_bytes", # Memory
    "datakit_open_files",
    "datakit_uptime_seconds",
    "datakit_data_overuse",
    "datakit_process_.*",

    ### election
    "datakit_election_status",

    ### Dataway related
    #"datakit_io_dataway_.*",
    #"datakit_io_http_retry_total",

    ### Filter
    #"datakit_filter_.*",

    ### dialtesting
    #"datakit_dialtesting_.*",

    ### Input feed
    #".*_feed_.*",
  ]

  # keep empty to collect all types(count/gauge/summary/...)
  metric_types = []

  # collect frequency
  interval = "30s"

[inputs.dk.tags]
   # tag1 = "val-1"
   # tag2 = "val-2"

配置好后,重启 DataKit 即可。

可通过 ConfigMap 方式注入采集器配置配置 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_DK_ENABLE_ALL_METRICS

    采集所有指标,任意非空字符串

    字段类型: Boolean

    采集器配置字段: -

    示例: true

    默认值: -

  • ENV_INPUT_DK_ADD_METRICS

    追加指标列表,可用的指标名参见这里

    字段类型: List

    采集器配置字段: -

    示例: ["datakit_io_.*", "datakit_pipeline_.*"]

    默认值: -

  • ENV_INPUT_DK_ONLY_METRICS

    只开启指定指标

    字段类型: List

    采集器配置字段: -

    示例: ["datakit_io_.*", "datakit_pipeline_.*"]

    默认值: -

指标

Datakit 自身指标主要是一些 Prometheus 指标,其文档参见这里
