Functions ¶

func AreIdenticalSeriesFast ¶ added in v1.66.0

func AreIdenticalSeriesFast(s1, s2 string) bool

AreIdenticalSeriesFast returns true if s1 and s2 contains identical Prometheus series with possible different values.

This function is optimized for speed.

func GetRowsDiff ¶ added in v1.66.0

func GetRowsDiff(s1, s2 string) string

GetRowsDiff returns rows from s1, which are missing in s2.

The returned rows have default value 0 and have no timestamps.

func MustParsePromMetrics ¶ added in v1.102.15

func MustParsePromMetrics(s string, offsetMsecs int64) []prompb.TimeSeries

MustParsePromMetrics parses metrics in Prometheus text exposition format from s and returns them.

Metrics must be delimited with newlines.

offsetMsecs is added to every timestamp in parsed metrics.

This function is for testing purposes only. Do not use it in non-test code.

func UnmarshalWithMetadata ¶ added in v1.110.16

func UnmarshalWithMetadata(dstRows Rows, dstMeta MetadataRows, s string, errLogger func(s string)) (Rows, MetadataRows)

UnmarshalWithMetadata unmarshals Prometheus exposition text into dstRows and dstMeta. See https://github.com/prometheus/docs/blob/e39897e4ee6e67d49d47204a34d120e3314e82f9/docs/instrumenting/exposition_formats.md#comments-help-text-and-type-information.

s shouldn't be modified while dstRows and dstMeta are in use.

type MetadataRows struct {
	Rows []Metadata
}

MetadataRows contains parsed Prometheus metadata rows.

func (*Rows) UnmarshalWithErrLogger ¶ added in v1.34.0

func (rs *Rows) UnmarshalWithErrLogger(s string, errLogger func(s string))

UnmarshalWithErrLogger unmarshals only samples from Prometheus exposition text.

See https://github.com/prometheus/docs/blob/e39897e4ee6e67d49d47204a34d120e3314e82f9/docs/instrumenting/exposition_formats.md#line-format
