    "use_sudo" : true,
    "exclude_devices": [
      "/dev/sda",
    ]
  }
```

The `smartmon` collector reads the data from the command `smartctl`. It retrieves S.M.A.R.T data from disks

Metrics:
* `smartmon_temp`: Temperature of the device (`unit=degC`)
* `smartmon_avail_spare`: Amount of spare left (`unit=percent`)
* `smartmon_percent_used`: Percentage of the device is used (`unit=percent`)
* `smartmon_data_units_read`: Read data units
* `smartmon_data_units_write`: Written data units
* `smartmon_host_reads`: Read operations
* `smartmon_host_writes`: Write operations
* `smartmon_power_cycles`: Number of power cycles
* `smartmon_power_on`: Seconds the device is powered on (`unit=seconds`)
* `smartmon_unsafe_shutdowns`: Count of unsafe shutdowns
* `smartmon_media_errors`: Media errors of the device
* `smartmon_errlog_entries`: Error log entries
* `smartmon_warn_temp_time`: Time above the warning temperature threshold
* `smartmon_crit_temp_time`: Time above the critical temperature threshold
