Types

type Duration added in v0.8.0 

type Duration time.Duration

Duration wraps time.Duration. It is used to parse the custom duration format from YAML. This type should not propagate beyond the scope of input/output processing.

func ParseDuration added in v0.8.0 

func ParseDuration(durationStr string) (Duration, error)

ParseDuration parses a string into a time.Duration, assuming that a year always has 365d, a week always has 7d, and a day always has 24h.

func (Duration) MarshalJSON added in v0.8.0 

func (d Duration) MarshalJSON() ([]byte, error)

MarshalJSON implements the json.Marshaler interface.

func (*Duration) MarshalText added in v0.8.0 

func (d *Duration) MarshalText() ([]byte, error)

MarshalText implements the encoding.TextMarshaler interface.

func (Duration) MarshalYAML added in v0.8.0 

func (d Duration) MarshalYAML() (interface{}, error)

MarshalYAML implements the yaml.Marshaler interface.

func (*Duration) Set added in v0.8.0 

func (d *Duration) Set(s string) error

Set implements pflag/flag.Value

func (Duration) String added in v0.8.0 

func (d Duration) String() string

func (*Duration) Type added in v0.8.0 

func (*Duration) Type() string

Type implements pflag.Value

func (*Duration) UnmarshalJSON added in v0.8.0 

func (d *Duration) UnmarshalJSON(bytes []byte) error

UnmarshalJSON implements the json.Unmarshaler interface.

func (*Duration) UnmarshalText added in v0.8.0 

func (d *Duration) UnmarshalText(text []byte) error

UnmarshalText implements the encoding.TextUnmarshaler interface.

func (*Duration) UnmarshalYAML added in v0.8.0

UnmarshalYAML implements the yaml.Unmarshaler interface.

type Interval added in v0.8.0 

type Interval struct {
	Start, End Time
}

Interval describes an interval between two timestamps.

type LabelName 

type LabelName string

A LabelName is a key for a LabelSet or Metric. It has a value associated therewith.

func (LabelName) IsValid 

func (ln LabelName) IsValid() bool

IsValid is true iff the label name matches the pattern of LabelNameRE. This method, however, does not use LabelNameRE for the check but a much faster hardcoded implementation.

func (*LabelName) UnmarshalJSON 

func (ln *LabelName) UnmarshalJSON(b []byte) error

UnmarshalJSON implements the json.Unmarshaler interface.

func (*LabelName) UnmarshalYAML 

func (ln *LabelName) UnmarshalYAML(unmarshal func(interface{}) error) error

UnmarshalYAML implements the yaml.Unmarshaler interface.

type LabelNames 

type LabelNames []LabelName

LabelNames is a sortable LabelName slice. In implements sort.Interface.

func (LabelNames) Len 

func (l LabelNames) Len() int

func (LabelNames) Less 

func (l LabelNames) Less(i, j int) bool

func (LabelNames) String 

func (l LabelNames) String() string

func (LabelNames) Swap 

func (l LabelNames) Swap(i, j int)

type LabelPair 

type LabelPair struct {
	Name  LabelName
	Value LabelValue
}

LabelPair pairs a name with a value.

type LabelPairs 

type LabelPairs []*LabelPair

LabelPairs is a sortable slice of LabelPair pointers. It implements sort.Interface.

func (LabelPairs) Len 

func (l LabelPairs) Len() int

func (LabelPairs) Less 

func (l LabelPairs) Less(i, j int) bool

func (LabelPairs) Swap 

func (l LabelPairs) Swap(i, j int)

type LabelSet 

type LabelSet map[LabelName]LabelValue

A LabelSet is a collection of LabelName and LabelValue pairs. The LabelSet may be fully-qualified down to the point where it may resolve to a single Metric in the data store or not. All operations that occur within the realm of a LabelSet can emit a vector of Metric entities to which the LabelSet may match.

func (LabelSet) Before 

func (ls LabelSet) Before(o LabelSet) bool

Before compares the metrics, using the following criteria:

If m has fewer labels than o, it is before o. If it has more, it is not.

If the number of labels is the same, the superset of all label names is sorted alphanumerically. The first differing label pair found in that order determines the outcome: If the label does not exist at all in m, then m is before o, and vice versa. Otherwise the label value is compared alphanumerically.

If m and o are equal, the method returns false.

func (LabelSet) Clone 

func (ls LabelSet) Clone() LabelSet

Clone returns a copy of the label set.

func (LabelSet) Equal 

func (ls LabelSet) Equal(o LabelSet) bool

Equal returns true iff both label sets have exactly the same key/value pairs.

func (LabelSet) Merge 

func (ls LabelSet) Merge(other LabelSet) LabelSet

Merge is a helper function to non-destructively merge two label sets.

func (LabelSet) String 

func (ls LabelSet) String() string

func (*LabelSet) UnmarshalJSON 

func (ls *LabelSet) UnmarshalJSON(b []byte) error

UnmarshalJSON implements the json.Unmarshaler interface.

func (LabelSet) Validate 

func (ls LabelSet) Validate() error

Validate checks whether all names and values in the label set are valid.

type LabelValue 

type LabelValue string

A LabelValue is an associated value for a LabelName.

func (LabelValue) IsValid 

func (lv LabelValue) IsValid() bool

IsValid returns true iff the string is a valid UTF8.

type LabelValues 

type LabelValues []LabelValue

LabelValues is a sortable LabelValue slice. It implements sort.Interface.

func (LabelValues) Len 

func (l LabelValues) Len() int

func (LabelValues) Less 

func (l LabelValues) Less(i, j int) bool

func (LabelValues) Swap 

func (l LabelValues) Swap(i, j int)
