Functions

func EngineQueryFunc

func EngineQueryFunc(engine *promql.Engine, q storage.Queryable, overrides RulesLimits, userID string) rules.QueryFunc

EngineQueryFunc returns a new query function using the rules.EngineQueryFunc function and passing an altered timestamp.

func MetricsQueryFunc

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

func NewErrorTranslateQueryableWithFn

func NewErrorTranslateQueryableWithFn(q storage.Queryable, fn ErrTranslateFn) storage.Queryable

func NewLegacyRuleStore

func NewLegacyRuleStore(cfg RuleStoreConfig, hedgeCfg hedging.Config, clientMetrics storage.ClientMetrics, loader promRules.GroupLoader, logger log.Logger) (rulestore.RuleStore, error)

NewLegacyRuleStore returns a rule store backend client based on the provided cfg. The client used by the function is based a legacy object store clients that shouldn't be used anymore.

func NewRuleStore

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

func RecordAndReportRuleQueryMetrics

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

func RegisterRulerServer

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

func SendAlerts

func SendAlerts(n sender, externalURL string) promRules.NotifyFunc

SendAlerts implements a rules.NotifyFunc for a Notifier. It filters any non-firing alerts from the input.

Copied from Prometheus's main.go.

func TranslateToPromqlAPIError

func TranslateToPromqlAPIError(err error) error

TranslateToPromqlAPIError converts error to one of promql.Errors for consumption in PromQL API. PromQL API only recognizes few errors, and converts everything else to HTTP status code 422.

Specifically, it supports:

promql.ErrQueryCanceled, mapped to 503
promql.ErrQueryTimeout, mapped to 503
promql.ErrStorage mapped to 500
anything else is mapped to 422

Querier code produces different kinds of errors, and we want to map them to above-mentioned HTTP status codes correctly.

Details: - vendor/github.com/prometheus/prometheus/web/api/v1/api.go, respondError function only accepts *apiError types. - translation of error to *apiError happens in vendor/github.com/prometheus/prometheus/web/api/v1/api.go, returnAPIError method.
