Functions

func AllowProtectionOverride 

func AllowProtectionOverride(reqHeaders http.Header, namespace string) error

AllowProtectionOverride checks if the request headers contain the protection override header and if the given namespace is in the list of overrides.

func DialQueryFrontend 

func DialQueryFrontend(cfg QueryFrontendConfig) (httpgrpc.HTTPClient, error)

DialQueryFrontend creates and initializes a new httpgrpc.HTTPClient taking a QueryFrontendConfig configuration.

func ExtractTenantIDs 

func ExtractTenantIDs(ctx context.Context) (string, error)

ExtractTenantIDs gets the rule group org ID from the context.

func FederatedGroupContextFunc 

func FederatedGroupContextFunc(ctx context.Context, g *rules.Group) context.Context

FederatedGroupContextFunc prepares the context for federated rules. It injects g.SourceTenants() in to the context to be used by mergeQuerier.

func MetricsQueryFunc 

func MetricsQueryFunc(qf rules.QueryFunc, queries, failedQueries prometheus.Counter, remoteQuerier bool) rules.QueryFunc

func NewRuleStore 

func NewRuleStore(ctx context.Context, cfg rulestore.Config, cfgProvider bucket.TenantConfigProvider, loader promRules.GroupLoader, cacheTTL time.Duration, logger log.Logger, reg prometheus.Registerer) (store rulestore.RuleStore, _ error)

NewRuleStore returns a rule store backend client based on the provided cfg.

func ProtectedNamespacesHeaderFromSet 

func ProtectedNamespacesHeaderFromSet(namespacesSet map[string]struct{}) http.Header

ProtectedNamespacesHeaderFromSet returns a http.Header with the given namespaces command-separated as the value and ProtectedNamespacesHeader as the key.

func ProtectedNamespacesHeaderFromString 

func ProtectedNamespacesHeaderFromString(namespace string) http.Header

ProtectedNamespacesHeaderFromString returns a http.Header with the given namespace as the value and ProtectedNamespacesHeader as the key.

func RecordAndReportRuleQueryMetrics 

func RecordAndReportRuleQueryMetrics(qf rules.QueryFunc, queryTime, zeroFetchedSeriesCount prometheus.Counter, logger log.Logger) rules.QueryFunc

func RegisterRulerServer 

func RegisterRulerServer(s *grpc.Server, srv RulerServer)

func TenantFederationQueryFunc 

func TenantFederationQueryFunc(regularQueryable, federatedQueryable rules.QueryFunc) rules.QueryFunc

func WithOrgIDMiddleware 

func WithOrgIDMiddleware(ctx context.Context, req *httpgrpc.HTTPRequest) error

WithOrgIDMiddleware attaches 'X-Scope-OrgID' header value to the outgoing request by inspecting the passed context. In case the expression to evaluate corresponds to a federated rule, the ExtractTenantIDs function will take care of normalizing and concatenating source tenants by separating them with a '|' character.

func WrapQueryFuncWithReadConsistency 

func WrapQueryFuncWithReadConsistency(fn rules.QueryFunc, logger log.Logger) rules.QueryFunc

WrapQueryFuncWithReadConsistency wraps rules.QueryFunc with a function that injects strong read consistency requirement in the context if the query is originated from a rule which depends on other rules in the same rule group.

func WrapQueryableErrors 

func WrapQueryableErrors(err error) error

func WrapQueryableWithReadConsistency 

func WrapQueryableWithReadConsistency(q storage.Queryable, logger log.Logger) storage.Queryable

WrapQueryableWithReadConsistency wraps storage.Queryable with a queryable that injects strong read consistency requirement in the context for any request matching ALERTS_FOR_STATE metric name.

The ALERTS_FOR_STATE metric is used to restore the state of a firing alert each time a rule Group is started. In case of Mimir, it could happen for example when the ruler starts, or rule groups are resharded among rulers.

When querying the ALERTS_FOR_STATE, ruler requires strong consistency in order to ensure we restore the state from the last evaluation. Without such guarantee, the ruler may query a previous state.
