Functions

func ComposeBucketFieldName

func ComposeBucketFieldName(lower, upper float64, isPositive bool) string

ComposeBucketFieldName generates the bucket count field name for histogram metrics.

func ComputeBucketBoundary

func ComputeBucketBoundary(fieldName string, isPositive bool) (float64, error)

ComputeBucketBoundary computes the bucket boundary from a field name.

func ComputeBuckets

func ComputeBuckets(multiValues models.MetricFloatValues, isPositive bool) (bucketBounds []float64, bucketCounts []float64)

ComputeBuckets computes the bucket boundarys and counts.

func IsInternalField

func IsInternalField(fieldname string) bool

func IsInternalTag

func IsInternalTag(tagname string) bool

When count is less than 20, direct comparison faster than map.

func ReverseSlice

func ReverseSlice[T comparable](s []T)

func SeverityTextToSeverityNumber

func SeverityTextToSeverityNumber(severityText string) plog.SeverityNumber

SeverityTextToSeverityNumber can convert a provided serverityText into its corresponding serverity number. It is case-insensitive and can accept the following serverityText values: Trace, Trace2, Trace3, Trace4, Debug, Debug2, Debug3, Debug4, Info, Info2, Info3, Info4, Information, Information2, Information3, Information4, Warn, Warn2, Warn3, Warn4, Warning, Warning2, Warning3, Warning4, Error, Error2, Error3, Error4, Fatal, Fatal2, Fatal3, Fatal4, and Unspecified. If the provided serverityText is not in this list, the function will return Unspecified by default.
