Functions

func DefaultMetricData 

func DefaultMetricData() pdata.Metrics

DefaultMetricData produces MetricData with a default config.

func GenerateMetricDatas 

func GenerateMetricDatas(metricPairsFile string) ([]pdata.Metrics, error)

GenerateMetricDatas takes the filename of a PICT-generated file, walks through all of the rows in the PICT file and for each row, generates a MetricData object, collecting them and returning them to the caller.

func GenerateResource 

func GenerateResource(rscID PICTInputResource) otlpresource.Resource

GenerateResource generates a OTLP Resource object with representative attributes for the underlying resource type specified by the rscID input parameter.

func GenerateResourceSpan 

func GenerateResourceSpan(tracingInputs *PICTTracingInputs, spanPairsFile string,
	random io.Reader) (*otlptrace.ResourceSpans, error)

GenerateResourceSpan generates a single OTLP ResourceSpans populated based on the provided inputs. They are: 

tracingInputs - the pairwise combination of field value variations for this ResourceSpans
spanPairsFile - the file with the PICT-generated parameter combinations to generate spans for
random - the random number generator to use in generating ID values

The generated resource spans. If err is not nil, some or all of the resource spans fields will be nil.

func GenerateResourceSpans 

func GenerateResourceSpans(tracePairsFile string, spanPairsFile string,
	random io.Reader) ([]*otlptrace.ResourceSpans, error)

GenerateResourceSpans generates a slice of OTLP ResourceSpans objects based on the PICT-generated pairwise parameters defined in the parameters file specified by the tracePairsFile parameter. The pairs to generate spans for for defined in the file specified by the spanPairsFile parameter. The random parameter injects the random number generator to use in generating IDs and other random values. The slice of ResourceSpans are returned. If an err is returned, the slice elements will be nil.

func GenerateSpan 

func GenerateSpan(traceID data.TraceID, parentID data.SpanID, spanName string, spanInputs *PICTSpanInputs,
	random io.Reader) *otlptrace.Span

GenerateSpan generates a single OTLP Span based on the input values provided. They are: 

traceID - the trace ID to use, should not be nil
parentID - the parent span ID or nil if it is a root span
spanName - the span name, should not be blank
spanInputs - the pairwise combination of field value variations for this span
random - the random number generator to use in generating ID values

The generated span is returned.

func GenerateSpans 

func GenerateSpans(count int, startPos int, pictFile string, random io.Reader) ([]*otlptrace.Span, int, error)

GenerateSpans generates a slice of OTLP Span objects with the number of spans specified by the count input parameter. The startPos parameter specifies the line in the PICT tool-generated, test parameter combination records file specified by the pictFile parameter to start reading from. When the end record is reached it loops back to the first record. The random parameter injects the random number generator to use in generating IDs and other random values. Using a random number generator with the same seed value enables reproducible tests.

The return values are the slice with the generated spans, the starting position for the next generation run and the error which caused the spans generation to fail. If err is not nil, the spans slice will have nil values.

func MetricDataFromCfg 

func MetricDataFromCfg(cfg MetricCfg) pdata.Metrics

MetricDataFromCfg produces MetricData with the passed-in config.

Types

type MetricCfg 

type MetricCfg struct {
	// The type of metric to generate
	MetricDescriptorType pdata.MetricDataType
	// If MetricDescriptorType is one of the Sum, this describes if the sum is monotonic or not.
	IsMonotonicSum bool
	// A prefix for every metric name
	MetricNamePrefix string
	// The number of instrumentation library metrics per resource
	NumILMPerResource int
	// The size of the MetricSlice and number of Metrics
	NumMetricsPerILM int
	// The number of labels on the LabelsMap associated with each point
	NumPtLabels int
	// The number of points to generate per Metric
	NumPtsPerMetric int
	// The number of Attributes to insert into each Resource's AttributesMap
	NumResourceAttrs int
	// The number of ResourceMetrics for the single MetricData generated
	NumResourceMetrics int

	// The start time for each point
	StartTime uint64
	// The duration of the steps between each generated point starting at StartTime

}

MetricCfg holds parameters for generating dummy metrics for testing. Set values on this struct to generate metrics with the corresponding number/type of attributes and pass into MetricDataFromCfg to generate metrics.

func DefaultCfg 

func DefaultCfg() MetricCfg

DefaultCfg produces a MetricCfg with default values. These should be good enough to produce sane (but boring) metrics, and can be used as a starting point for making alterations.
