Variables

var MapAttributeState = map[string]AttributeState{
	"free":     AttributeStateFree,
	"reserved": AttributeStateReserved,
	"used":     AttributeStateUsed,
}

MapAttributeState is a helper map of string to AttributeState attribute value.

Functions

func WithStartTime

func WithStartTime(startTime pcommon.Timestamp) metricBuilderOption

WithStartTime sets startTime on the metrics builder.

Types

type AttributeState

type AttributeState int

AttributeState specifies the a value state attribute.

const (
	AttributeStateFree AttributeState
	AttributeStateReserved
	AttributeStateUsed
)

func (AttributeState) String

func (av AttributeState) String() string

String returns the string representation of the AttributeState.

type MetricSettings

type MetricSettings struct {
	Enabled bool `mapstructure:"enabled"`
}

MetricSettings provides common settings for a particular metric.

type MetricsBuilder

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

MetricsBuilder provides an interface for scrapers to report metrics while taking care of all the transformations required to produce metric representation defined in metadata and user settings.

func NewMetricsBuilder

func NewMetricsBuilder(settings MetricsSettings, buildInfo component.BuildInfo, options ...metricBuilderOption) *MetricsBuilder

func (*MetricsBuilder) Emit

func (mb *MetricsBuilder) Emit(rmo ...ResourceMetricsOption) pmetric.Metrics

Emit returns all the metrics accumulated by the metrics builder and updates the internal state to be ready for recording another set of metrics. This function will be responsible for applying all the transformations required to produce metric representation defined in metadata and user settings, e.g. delta or cumulative.

func (*MetricsBuilder) EmitForResource

func (mb *MetricsBuilder) EmitForResource(rmo ...ResourceMetricsOption)

EmitForResource saves all the generated metrics under a new resource and updates the internal state to be ready for recording another set of data points as part of another resource. This function can be helpful when one scraper needs to emit metrics from several resources. Otherwise calling this function is not required, just `Emit` function can be called instead. Resource attributes should be provided as ResourceMetricsOption arguments.

func (*MetricsBuilder) RecordSystemFilesystemInodesUsageDataPoint

func (mb *MetricsBuilder) RecordSystemFilesystemInodesUsageDataPoint(ts pcommon.Timestamp, val int64, deviceAttributeValue string, modeAttributeValue string, mountpointAttributeValue string, typeAttributeValue string, stateAttributeValue AttributeState)

RecordSystemFilesystemInodesUsageDataPoint adds a data point to system.filesystem.inodes.usage metric.

func (*MetricsBuilder) RecordSystemFilesystemUsageDataPoint

func (mb *MetricsBuilder) RecordSystemFilesystemUsageDataPoint(ts pcommon.Timestamp, val int64, deviceAttributeValue string, modeAttributeValue string, mountpointAttributeValue string, typeAttributeValue string, stateAttributeValue AttributeState)

RecordSystemFilesystemUsageDataPoint adds a data point to system.filesystem.usage metric.

func (*MetricsBuilder) RecordSystemFilesystemUtilizationDataPoint

func (mb *MetricsBuilder) RecordSystemFilesystemUtilizationDataPoint(ts pcommon.Timestamp, val float64, deviceAttributeValue string, modeAttributeValue string, mountpointAttributeValue string, typeAttributeValue string)

RecordSystemFilesystemUtilizationDataPoint adds a data point to system.filesystem.utilization metric.

func (*MetricsBuilder) Reset

func (mb *MetricsBuilder) Reset(options ...metricBuilderOption)

Reset resets metrics builder to its initial state. It should be used when external metrics source is restarted, and metrics builder should update its startTime and reset it's internal state accordingly.

type MetricsSettings

type MetricsSettings struct {
	SystemFilesystemInodesUsage MetricSettings `mapstructure:"system.filesystem.inodes.usage"`
	SystemFilesystemUsage       MetricSettings `mapstructure:"system.filesystem.usage"`
	SystemFilesystemUtilization MetricSettings `mapstructure:"system.filesystem.utilization"`
}

MetricsSettings provides settings for hostmetricsreceiver/filesystem metrics.

func DefaultMetricsSettings

func DefaultMetricsSettings() MetricsSettings

type ResourceMetricsOption

type ResourceMetricsOption func(pmetric.ResourceMetrics)

ResourceMetricsOption applies changes to provided resource metrics.

func WithStartTimeOverride

func WithStartTimeOverride(start pcommon.Timestamp) ResourceMetricsOption

WithStartTimeOverride overrides start time for all the resource metrics data points. This option should be only used if different start time has to be set on metrics coming from different resources.
