Functions

func IsConnCanceled

func IsConnCanceled(err error) bool

IsConnCanceled returns true, if error is from a closed gRPC connection. copied from https://github.com/etcd-io/etcd/blob/7f47de84146bdc9225d2080ec8678ca8189a2d2b/clientv3/client.go#L646

func LabelsToMetric

func LabelsToMetric(ls labels.Labels) model.Metric

LabelsToMetric converts a Labels to Metric Don't do this on any performance sensitive paths.

func LogConfig

func LogConfig(cfg interface{}) error

LogConfig takes a pointer to a config object, marshalls it to YAML and prints each line in REVERSE order The reverse order makes display in Grafana in easier which typically sorts newest entries at the top.

func MergeStringLists

func MergeStringLists(ss ...[]string) []string

func MergeStringPair

func MergeStringPair(s1, s2 []string) []string

func ModelLabelSetToMap

func ModelLabelSetToMap(m model.LabelSet) map[string]string

ModelLabelSetToMap convert a model.LabelSet to a map[string]string

func PrintConfig

func PrintConfig(w io.Writer, config interface{}) error

PrintConfig will takes a pointer to a config object, marshalls it to YAML and prints the result to the provided writer unlike LogConfig, PrintConfig prints the object in naturally ocurring order.

func RoundToMilliseconds

func RoundToMilliseconds(from, through time.Time) (model.Time, model.Time)

RoundToMilliseconds returns milliseconds precision time from nanoseconds. from will be rounded down to the nearest milliseconds while through is rounded up.

func StringRef

func StringRef(value string) *string

func StringSliceContains

func StringSliceContains(slice []string, value string) bool

func ToClientLabels

func ToClientLabels(labels string) ([]client.LabelAdapter, error)

ToClientLabels parses the labels and converts them to the Cortex type.

func TokenFor

func TokenFor(userID, labels string) uint32

TokenFor generates a token used for finding ingesters from ring
