func NewRulesHandler

func NewRulesHandler(client rules.UnaryClient, enablePartialResponse bool) func(*http.Request) (interface{}, []error, *api.ApiError)

NewRulesHandler created handler compatible with HTTP /api/v1/rules https://prometheus.io/docs/prometheus/latest/querying/api/#rules which uses gRPC Unary Rules API.

func NewTargetsHandler

func NewTargetsHandler(client targets.UnaryClient, enablePartialResponse bool) func(*http.Request) (interface{}, []error, *api.ApiError)

NewTargetsHandler created handler compatible with HTTP /api/v1/targets https://prometheus.io/docs/prometheus/latest/querying/api/#targets which uses gRPC Unary Targets API.

func RegisterQueryServer

func RegisterQueryServer(queryServer querypb.QueryServer) func(*grpc.Server)
