磁盘

磁盘采集器用于主机磁盘信息采集，如磁盘存储空间、Inode 使用情况等。

配置

成功安装 DataKit 并启动后，会默认开启 Disk 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 disk.conf.sample 并命名为 disk.conf。示例如下：

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

  ## Physical devices only (e.g. hard disks, cd-rom drives, USB keys)
  ## and ignore all others (e.g. memory partitions such as /dev/shm)
  only_physical_device = false

  ## Deprecated
  # ignore_mount_points = ["/"]

  ## Deprecated
  # mount_points = ["/"]

  ## Deprecated
  # ignore_fs = ["tmpfs", "devtmpfs", "devfs", "iso9660", "overlay", "aufs", "squashfs"]

  ## Deprecated
  # fs = ["ext2", "ext3", "ext4", "NTFS"]

  ## We collect all devices prefixed with dev by default,If you want to collect additional devices, it's in extra_device add
  # extra_device = ["/nfsdata"]

  ## exclude some with dev prefix (We collect all devices prefixed with dev by default)
  # exclude_device = ["/dev/loop0","/dev/loop1"]

  [inputs.disk.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_DISK_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_DISK_EXTRA_DEVICE

    额外的设备前缀。（默认收集以 dev 为前缀的所有设备）

    字段类型: List

    采集器配置字段: extra_device

    示例: /nfsdata,other_data

  • ENV_INPUT_DISK_EXCLUDE_DEVICE

    排除的设备前缀。（默认收集以 dev 为前缀的所有设备）

    字段类型: List

    采集器配置字段: exclude_device

    示例: /dev/loop0,/dev/loop1

  • ENV_INPUT_DISK_ONLY_PHYSICAL_DEVICE

    忽略非物理磁盘（如网盘、NFS 等，只采集本机硬盘/CD ROM/USB 磁盘等）

    字段类型: Boolean

    采集器配置字段: only_physical_device

    默认值: false

  • ENV_INPUT_DISK_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: Map

    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.disk.tags] 指定其它标签：

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

disk
