Functions

func DeletePerUserValidationMetrics added in v1.8.0 

func DeletePerUserValidationMetrics(validateMetrics *ValidateMetrics, userID string, log log.Logger)

func MaxDurationPerTenant added in v1.7.0 

func MaxDurationPerTenant(tenantIDs []string, f func(string) time.Duration) time.Duration

MaxDurationPerTenant is returning the maximum duration per tenant. Without tenants given it will return a time.Duration(0).

func SetDefaultLimitsForYAMLUnmarshalling added in v0.6.0 

func SetDefaultLimitsForYAMLUnmarshalling(defaults Limits)

SetDefaultLimitsForYAMLUnmarshalling sets global default limits, used when loading Limits from YAML files. This is used to ensure per-tenant limits are defaulted to those values.

func SmallestPositiveIntPerTenant added in v1.7.0 

func SmallestPositiveIntPerTenant(tenantIDs []string, f func(string) int) int

SmallestPositiveIntPerTenant is returning the minimal positive value of the supplied limit function for all given tenants.

func SmallestPositiveNonZeroDurationPerTenant added in v1.7.0 

func SmallestPositiveNonZeroDurationPerTenant(tenantIDs []string, f func(string) time.Duration) time.Duration

SmallestPositiveNonZeroDurationPerTenant is returning the minimal positive and non-zero value of the supplied limit function for all given tenants. In many limits a value of 0 means unlimited so the method will return 0 only if all inputs have a limit of 0 or an empty tenant list is given.

func SmallestPositiveNonZeroFloat64PerTenant added in v1.16.0 

func SmallestPositiveNonZeroFloat64PerTenant(tenantIDs []string, f func(string) float64) float64

SmallestPositiveNonZeroFloat64PerTenant is returning the minimal positive and non-zero value of the supplied limit function for all given tenants. In many limits a value of 0 means unlimited so the method will return 0 only if all inputs have a limit of 0 or an empty tenant list is given.

func ValidateMetadata added in v1.1.0 

func ValidateMetadata(validateMetrics *ValidateMetrics, cfg *Limits, userID string, metadata *cortexpb.MetricMetadata) error

ValidateMetadata returns an err if a metric metadata is invalid.

func ValidateNativeHistogram added in v1.18.0 

func ValidateNativeHistogram(validateMetrics *ValidateMetrics, limits *Limits, userID string, ls []cortexpb.LabelAdapter, histogramSample cortexpb.Histogram) (cortexpb.Histogram, error)
