Types

type Capture

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

Capture polls data sources (resource/method pairs) and writes the responses files. There must be only one Capture per DataManager.

The lifecycle of a Capture is:

- New - Reconfigure (any number of times) - Close (any number of times).

func New

func New(
	clock clock.Clock,
	logger logging.Logger,
) *Capture

New creates a new capture manager.

func (*Capture) Close

func (c *Capture) Close()

Close closes the capture manager.

func (*Capture) FlushCollectors

func (c *Capture) FlushCollectors()

FlushCollectors flushes collectors.

func (*Capture) Reconfigure

func (c *Capture) Reconfigure(
	ctx context.Context,
	collectorConfigsByResource CollectorConfigsByResource,
	config Config,
)

Reconfigure reconfigures Capture. It is only called by the builtin data manager.

type CollectorConfigsByResource

type CollectorConfigsByResource map[resource.Resource][]datamanager.DataCaptureConfig

CollectorConfigsByResource describes the data capture configuration of the resources/mathod pairs which data capture should capture data from.

type Config

type Config struct {
	// CaptureDisabled if set to true disables all data capture collectors
	CaptureDisabled bool
	// CaptureDir defines where data capture should write capture files
	CaptureDir string
	// Tags defines the tags that should be added to capture file metadata
	Tags []string
	// MaximumCaptureFileSizeBytes defines the maximum size that in progress data capture
	// (.prog) files should be allowed to grow to before they are convered into .capture
	// files
	MaximumCaptureFileSizeBytes int64
}

Config is the capture config.
