Functions

func WithStartTime added in v0.50.0 

func WithStartTime(startTime pcommon.Timestamp) metricBuilderOption

WithStartTime sets startTime on the metrics builder.

Types

type MetricSettings added in v0.50.0 

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

MetricSettings provides common settings for a particular metric.

type MetricsBuilder added in v0.50.0 

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 added in v0.50.0 

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

func (*MetricsBuilder) Emit added in v0.50.0 

func (mb *MetricsBuilder) Emit(ro ...ResourceOption) 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 added in v0.50.0 

func (mb *MetricsBuilder) EmitForResource(ro ...ResourceOption)

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 ResourceOption arguments.

func (*MetricsBuilder) RecordMemcachedBytesDataPoint added in v0.50.0 

func (mb *MetricsBuilder) RecordMemcachedBytesDataPoint(ts pcommon.Timestamp, val int64)

RecordMemcachedBytesDataPoint adds a data point to memcached.bytes metric.

func (*MetricsBuilder) RecordMemcachedCPUUsageDataPoint added in v0.50.0 

func (mb *MetricsBuilder) RecordMemcachedCPUUsageDataPoint(ts pcommon.Timestamp, val float64, stateAttributeValue string)

RecordMemcachedCPUUsageDataPoint adds a data point to memcached.cpu.usage metric.

func (*MetricsBuilder) RecordMemcachedCommandsDataPoint added in v0.50.0 

func (mb *MetricsBuilder) RecordMemcachedCommandsDataPoint(ts pcommon.Timestamp, val int64, commandAttributeValue string)

RecordMemcachedCommandsDataPoint adds a data point to memcached.commands metric.

func (*MetricsBuilder) RecordMemcachedConnectionsCurrentDataPoint added in v0.50.0 

func (mb *MetricsBuilder) RecordMemcachedConnectionsCurrentDataPoint(ts pcommon.Timestamp, val int64)

RecordMemcachedConnectionsCurrentDataPoint adds a data point to memcached.connections.current metric.

func (*MetricsBuilder) Reset added in v0.50.0 

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 added in v0.50.0 

type MetricsSettings struct {
	MemcachedBytes              MetricSettings `mapstructure:"memcached.bytes"`
