func SerializeCells Uses

func SerializeCells(cells []types.Cell, now time.Time) []*pb.MetricsCollection

SerializeCells creates a MetricsCollection message from a slice of cells.

func SerializeDataSet Uses

func SerializeDataSet(c types.Cell) *pb.MetricsDataSet

SerializeDataSet creates a new MetricsDataSet without any data, but just with the metric metadata fields populated.

func SerializeValue Uses

func SerializeValue(c types.Cell, now time.Time) *pb.MetricsData

SerializeValue creates a new MetricsData representing this cell's value.

type Fake Uses

type Fake struct {
    CS      int
    Cells   [][]types.Cell
    SendErr error
}

Fake is a fake Monitor.

func (*Fake) ChunkSize Uses

func (m *Fake) ChunkSize() int

ChunkSize returns the fake value.

func (*Fake) Close Uses

func (m *Fake) Close() error

Close always works.

func (*Fake) Send Uses

func (m *Fake) Send(c context.Context, cells []types.Cell) error

Send appends the cells to Cells, unless SendErr is set.

type Monitor Uses

type Monitor interface {
    // ChunkSize returns the maximum number of metrics this Monitor can Send in
    // one go.  If there are more metrics, they will be broken up into chunks and
    // Send will be called multiple times.  A ChunkSize of 0 disables chunking.
    ChunkSize() int

    Send(ctx context.Context, cells []types.Cell) error

    // Close closes any resources held by the monitor.
    //
    // Close need not be called at program exit.
    Close() error
}

A Monitor can send a collection of metrics somewhere.

func NewDebugMonitor Uses

func NewDebugMonitor(path string) Monitor

NewDebugMonitor returns a Monitor that outputs metrics to a log, and optionally a file on disk.

func NewHTTPMonitor Uses

func NewHTTPMonitor(ctx context.Context, client *http.Client, endpoint *url.URL) (Monitor, error)

NewHTTPMonitor creates a new Monitor object that sends metric to an HTTP (or HTTPS) endpoint. The http client should be authenticated as required.

func NewNilMonitor Uses

func NewNilMonitor() Monitor

NewNilMonitor returns a Monitor that does nothing.
