type UnRegisterer added in v0.8.0 

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

UnRegisterer is a Prometheus registerer that ensures that collectors can be registered by unregistering already-registered collectors. FlushableStorage uses this registerer in order to not lose metric values between DB flushes.

This type cannot embed the inner registerer, because Prometheus since v2.39.0 is wrapping the Registry with prometheus.WrapRegistererWithPrefix. This wrapper will call the Register function of the wrapped registerer. If UnRegisterer is the wrapped registerer, this would end up calling the inner registerer's Register, which doesn't implement the "unregister" logic that this type intends to use.

func NewUnRegisterer added in v0.29.0 

func NewUnRegisterer(inner prometheus.Registerer) *UnRegisterer

func (*UnRegisterer) MustRegister added in v0.8.0

func (*UnRegisterer) Register added in v0.29.0 

func (u *UnRegisterer) Register(c prometheus.Collector) error

Register registers the given collector. If it's already registered, it will be unregistered and registered.

func (*UnRegisterer) Unregister added in v0.29.0 

func (u *UnRegisterer) Unregister(c prometheus.Collector) bool

Unregister unregisters the given collector.

type WriteLimitConfig added in v0.29.0 

type WriteLimitConfig struct {
	// RequestLimits holds the difficult per-request limits.
	RequestLimits *requestLimitsConfig `yaml:"request"`
	// HeadSeriesLimit specifies the maximum number of head series allowed for a tenant.
	HeadSeriesLimit *uint64 `yaml:"head_series_limit"`
}

A tenant might not always have limits configured, so things here must use pointers.

Utils for initializing.

func (*WriteLimitConfig) SetHeadSeriesLimit added in v0.29.0

	DefaultLimits DefaultLimitsConfig `yaml:"default"`
	// TenantsLimits are the limits per tenant.
	TenantsLimits TenantsWriteLimitsConfig `yaml:"tenants"`
}
