Types

type Adapter

type Adapter struct {
	// contains filtered or unexported fields
}

Adapter allows querying and writing Stackdriver metrics.

func NewAdapter

func NewAdapter(ctx context.Context, lookbackInterval time.Duration) (*Adapter, error)

NewAdapter returns a new Stackdriver adapter.

func (*Adapter) Close

func (a *Adapter) Close() error

Close closes the underlying metric client.

func (*Adapter) CreateTimeseries

func (a *Adapter) CreateTimeseries(ctx context.Context, project, name string, desc *metricpb.MetricDescriptor, series []*monitoringpb.TimeSeries) error

CreateTimeseries writes time series data (new data points) for a given metric into Stackdriver. It also creates a metric descriptor if it does not exist.

func (*Adapter) LatestTimestamp

func (a *Adapter) LatestTimestamp(ctx context.Context, project, name string) (time.Time, error)

LatestTimestamp determines the timestamp of a latest point for a given metric in SD. If metric does not exist, a timestamp which is `lookBackInterval` ago in the past is returned to backfill some data.

type MetricClient

type MetricClient interface {
	CreateMetricDescriptor(context.Context, *monitoringpb.CreateMetricDescriptorRequest) (*metricpb.MetricDescriptor, error)
	GetMetricDescriptor(context.Context, *monitoringpb.GetMetricDescriptorRequest) (*metricpb.MetricDescriptor, error)
	DeleteMetricDescriptor(ctx context.Context, req *monitoringpb.DeleteMetricDescriptorRequest) error
	CreateTimeSeries(context.Context, *monitoringpb.CreateTimeSeriesRequest) error
	ListTimeSeries(context.Context, *monitoringpb.ListTimeSeriesRequest) ([]*monitoringpb.TimeSeries, error)
	Close() error
}

MetricClient defines Stackdriver functions used by the metric adapter.
