Lsblk
lsblk 采集器用于 Linux 主机块设备信息采集，如设备名称、主次设备号、文件系统可用大小、文件系统类型、文件系统已用大小、文件系统使用百分比、设备挂载位置等。
配置¶
进入 DataKit 安装目录下的 conf.d/samples 目录，复制 lsblk.conf.sample 并命名为 lsblk.conf。示例如下：
[[inputs.lsblk]]
##(optional) collect interval, default is 10 seconds
interval = '10s'
# exclude_device = ['/dev/sda1','/dev/sda2']
[inputs.lsblk.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_LSBLK_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_LSBLK_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
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.lsblk.tags] 指定其它标签：
