Functions

func ComponentTypes 

func ComponentTypes() []string

func FormatProductName 

func FormatProductName(s string) string

Return a normalized product name given a product name

nolint:gocyclo // This list is expected to be long.

func FormatVendorName 

func FormatVendorName(name string) string

FormatVendorName compares the given strings to identify and returned a known vendor name. When a match is not found, the string is returned as is.

Note: This method will most likely return incorrect matches if the given vendor string is too short and or not unique enough.

func VendorFromString 

func VendorFromString(s string) string

Return the product vendor name, given a product name/model string

type DriveSmartAttributes 

type DriveSmartAttributes struct {
	// Name is the SMART attribute name.
	Name string `json:"name,omitempty"`

	// Each vendor uses their own algorithm to convert this "Raw" value to a "Normalized" value
	// in the range from 1 to 254. Please keep in mind that smartctl only reports the different Attribute types,
	// values, and thresholds as read from the device. It does not carry out the conversion between "Raw" and
	// "Normalized" values: this is done by the disk's firmware.
	NormalizedValue int `json:"normalized_value,omitempty"`

	// Each Attribute also has a "Worst" value shown under the heading "WORST".
	// This is the smallest (closest to failure) value that the disk has recorded at any time during its lifetime when SMART was enabled.
	// [Note however that some vendors firmware may actually increase the "Worst" value for some "rate-type" Attributes.]
	Worst int `json:"worst,omitempty"`

	// Each Attribute also has a Threshold value (whose range is 0 to 255) which is printed under the heading "THRESH".
	// If the Normalized value is less than or equal to the Threshold value, then the Attribute is said to have failed.
	// If the Attribute is a pre-failure Attribute, then disk failure is imminent.
	Threshold int `json:"threshold,omitempty"`

	// If the Normalized value is less than or equal to the Threshold value, then the Attribute is said to have failed.
	// If the Attribute is a pre-failure Attribute, then disk failure is imminent.
	PreFailure bool `json:"prefailure,omitempty"`

	// Some SMART attribute values are updated only during off-line data collection activities;
	// the rest are updated during normal operation of the device or during both normal operation and off-line testing.
	UpdatedOnline bool `json:"updated_online,omitempty"`
}

DriveSmartAttributes holds SMART attributes for a drive.
