Functions ¶

func FailureMetricLabels ¶ added in v1.6.6

func FailureMetricLabels(base map[string]string, phase string, extra ...map[string]string) map[string]string

FailureMetricLabels produces a failure metric label set by merging the provided base labels with the phase label and any additional label maps. Later maps override earlier values when conflicts occur.

func FindMetricWithLabelValues ¶ added in v1.6.6

func FindMetricWithLabelValues(metricName string, labels map[string]string) (*dto.Metric, error)

FindMetricWithLabelValues locates a metric by name and label values within the controller-runtime registry. It returns the metric (or nil if not found) and any error produced while gathering metrics.

func ValuesToKeyValuePairs ¶ added in v1.6.2

func ValuesToKeyValuePairs(values ...Value) []any

Helper function to convert a slice of Values to their key-value pairs

Types ¶

type Value ¶ added in v1.6.2

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

Value represents a key-value pair for logging with a known key

func ImageID ¶ added in v1.6.2

func ImageID(value string) Value

func ResponseError ¶ added in v1.6.3

func ResponseError(value string) Value

func (Value) Key ¶ added in v1.6.2

func (m Value) Key() string

Key returns the logging key

func (Value) Value ¶ added in v1.6.2

func (m Value) Value() any

Value returns the logging value
