Functions

func AllTrueBooleansPerTenant 

func AllTrueBooleansPerTenant(tenantIDs []string, f func(string) bool) bool

AllTrueBooleansPerTenant returns true only if limit func is true for all given tenants

func DiscardedExemplarsCounter 

func DiscardedExemplarsCounter(reg prometheus.Registerer, reason string) *prometheus.CounterVec

DiscardedExemplarsCounter creates per-user counter vector for exemplars discarded for a given reason.

func DiscardedMetadataCounter 

func DiscardedMetadataCounter(reg prometheus.Registerer, reason string) *prometheus.CounterVec

DiscardedMetadataCounter creates per-user counter vector for metadata discarded for a given reason.

func DiscardedRequestsCounter 

func DiscardedRequestsCounter(reg prometheus.Registerer, reason string) *prometheus.CounterVec

DiscardedRequestsCounter creates per-user counter vector for requests discarded for a given reason.

func DiscardedSamplesCounter 

func DiscardedSamplesCounter(reg prometheus.Registerer, reason string) *prometheus.CounterVec

DiscardedSamplesCounter creates per-user counter vector for samples discarded for a given reason.

func GroupLabel 

func GroupLabel(o *Overrides, userID string, timeseries []mimirpb.PreallocTimeseries) string

GroupLabel obtains the first non-empty group label from the first timeseries in the list of incoming timeseries.

func IsLimitError 

func IsLimitError(err error) bool

func MaxDurationPerTenant 

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 MinDurationPerTenant 

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

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

func MustRegisterExtension 

func MustRegisterExtension[E interface{ Default() E }](name string) func(*Limits) E

MustRegisterExtension registers the extensions type with given name and returns a function to get the extensions value from a *Limits instance.

The provided name will be used as YAML/JSON key to decode the extensions.

The returned getter will return the result of E.Default() if *Limits is nil.

This method is not thread safe and should be called only during package initialization. Registering same name twice, or registering a name that is already a *Limits JSON or YAML key will cause a panic.

func SetDefaultLimitsForYAMLUnmarshalling 

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 

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 

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 SmallestPositiveNonZeroIntPerTenant 

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

SmallestPositiveNonZeroIntPerTenant 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 UserLimitsHandler 

func UserLimitsHandler(defaultLimits Limits, tenantLimits TenantLimits) http.HandlerFunc

UserLimitsHandler handles user limits.

Types

type BlockedQuery 

type BlockedQuery struct {
	Pattern string `yaml:"pattern"`
	Regex   bool   `yaml:"regex"`
}

type LimitError 

type LimitError interface {
	error
	// contains filtered or unexported methods
}

LimitError is a marker interface for the errors that do not comply with the specified limits.

func NewLimitError 

func NewLimitError(msg string) LimitError
