disk 采集器用于主机磁盘信息采集，如磁盘存储空间、inodes 使用情况等。

配置

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。

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_DISK_EXCLUDE_DEVICE exclude_device "/dev/loop0","/dev/loop1" 以英文逗号隔开
ENV_INPUT_DISK_EXTRA_DEVICE extra_device "/nfsdata" 以英文逗号隔开
ENV_INPUT_DISK_TAGS tags tag1=value1,tag2=value2 如果配置文件中有同名 tag，会覆盖它
ENV_INPUT_DISK_ONLY_PHYSICAL_DEVICE 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）任意给一个字符串值即可
ENV_INPUT_DISK_INTERVAL interval 10s

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.disk.tags] 指定其它标签：

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