type Graphite ¶

type Graphite struct{}

func (Graphite) Id() db.ResourceType

func (Graphite) Name() string

func (Graphite) Scripts() []string

func (Graphite) Templates() string

type GraphiteDaemon ¶

type GraphiteDaemon struct {
	// Base is the URL where the server can be found. Base should have a
	// trailing slash, with the expectation that the render API endpoint is
	// at Base + "render".
	Base string
}

GraphiteDaemon represents a remote Graphite server. For more information, see http://graphite.readthedocs.org/ .

func (g GraphiteDaemon) Query(target string, from, until time.Time) ([]GraphiteSeries, error)

func (g GraphiteDaemon) QueryRecent(target string, d time.Duration) ([]GraphiteSeries, error)

func (g GraphiteDaemon) RenderURL(targets []string, args map[string]string) string

type GraphiteResource ¶

type GraphiteResource struct {
	Graphite
	URL string
}

func (g GraphiteResource) Serialize() (string, error)

func (g GraphiteResource) Type() ResourceType

func (g GraphiteResource) Validate() []string

type GraphiteResourceDBModel ¶

type GraphiteResourceDBModel struct {
	URL string
}

Eventually implemented in DB layer

type GraphiteSeries ¶

type GraphiteSeries struct {
	Name       string
	Start, End time.Time
	Step       time.Duration
	Values     []float64
}

GraphiteSeries encapsulates the data returned by Graphite for a particular series. The values in Values correspond to the times between Start and End, inclusive, that are Step times apart. Null values are represented by NaN.

XXX(eefi): It is possible to store NaN in Graphite, and encoding nulls as NaN makes those cases indistinguishable. However, actual NaNs should be rare, and encoding nulls as NaN removes the need for an extra layer of pointer indirection.

type Resource ¶

type Resource interface {
	ResourceType
	Serialize() (string, error)
	Type() ResourceType
	Validate() []string
}

func Blank(id db.ResourceType) (Resource, error)

func Default() (Resource, error)

func LoadFromDB(id db.ResourceType, dsJson string) (Resource, error)

func LoadFromParams(id db.ResourceType, dsParams string) (Resource, error)

type ResourceType ¶

type ResourceType interface {
	Id() db.ResourceType
	Name() string

	Templates() string
	Scripts() []string
	// contains filtered or unexported methods
}

ResourceType and Resource define a common display abstraction for all Resources.

type VM ¶

type VM struct {
	Resource
	ResourceParams string
	ResourceType   db.ResourceType
	ResourceID     db.ResourceID
	Delete         bool
}

The VM struct is practically identical in purpose to its counterparts in the vm package, as it represents the intermediate structure between Revere's DB representation of the Resource and its front end representation of the Resource.

func All(DB *db.DB) ([]*VM, error)

func AllOfTypes(DB *db.DB, ids []db.ResourceType) ([]*VM, error)

func (*VM) ComponentName() string

func (vm *VM) Id() int64

func (vm *VM) IsCreate() bool

func (vm *VM) IsDelete() bool

func (vm *VM) Save(tx *db.Tx) error

func (vm *VM) Validate() (errs []string)
