type EndpointSet added in v0.23.0

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

EndpointSet maintains a set of active Thanos endpoints. It is backed up by Endpoint Specifications that are dynamically fetched on every Update() call.

func NewEndpointSet added in v0.23.0

func NewEndpointSet(
	now nowFunc,
	logger log.Logger,
	reg prometheus.Registerer,
	endpointSpecs func() []*GRPCEndpointSpec,
	dialOpts []grpc.DialOption,
	unhealthyEndpointTimeout time.Duration,
	endpointInfoTimeout time.Duration,
	endpointMetricLabels ...string,
) *EndpointSet

NewEndpointSet returns a new set of Thanos APIs.

func (*EndpointSet) Close added in v0.23.0

func (e *EndpointSet) Close()

func (*EndpointSet) GetEndpointStatus added in v0.23.0

func (e *EndpointSet) GetEndpointStatus() []EndpointStatus

func (*EndpointSet) GetExemplarsStores added in v0.23.0

func (e *EndpointSet) GetExemplarsStores() []*exemplarspb.ExemplarStore

GetExemplarsStores returns a list of all active exemplars stores.

func (*EndpointSet) GetMetricMetadataClients added in v0.23.0

func (e *EndpointSet) GetMetricMetadataClients() []metadatapb.MetadataClient

GetMetricMetadataClients returns a list of all active metadata clients.

func (*EndpointSet) GetQueryAPIClients added in v0.26.0

func (e *EndpointSet) GetQueryAPIClients() []Client

GetQueryAPIClients returns a list of all active query API clients.

func (*EndpointSet) GetRulesClients added in v0.23.0

func (e *EndpointSet) GetRulesClients() []rulespb.RulesClient

GetRulesClients returns a list of all active rules clients.

func (*EndpointSet) GetStoreClients added in v0.23.0

func (e *EndpointSet) GetStoreClients() []store.Client

func (*EndpointSet) Update added in v0.23.0

func (e *EndpointSet) Update(ctx context.Context)

Update updates the endpoint set. It fetches current list of endpoint specs from function and updates the fresh metadata from all endpoints. Keeps around statically defined nodes that were defined with the strict mode.

type EndpointStatus added in v0.23.0

type EndpointStatus struct {
	Name          string              `json:"name"`
	LastCheck     time.Time           `json:"lastCheck"`
	LastError     *stringError        `json:"lastError"`
	LabelSets     []labels.Labels     `json:"labelSets"`
	ComponentType component.Component `json:"-"`
	MinTime       int64               `json:"minTime"`
	MaxTime       int64               `json:"maxTime"`
}

type GRPCEndpointSpec added in v0.24.0

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

func NewGRPCEndpointSpec added in v0.23.0

func NewGRPCEndpointSpec(addr string, isStrictStatic bool, dialOpts ...grpc.DialOption) *GRPCEndpointSpec

NewGRPCEndpointSpec creates gRPC endpoint spec. It uses InfoAPI to get Metadata.

func (*GRPCEndpointSpec) Addr added in v0.24.0

func (es *GRPCEndpointSpec) Addr() string

type Opts added in v0.31.0

type Opts struct {
	AutoDownsample        bool
	ReplicaLabels         []string
	Timeout               time.Duration
	EnablePartialResponse bool
}

Opts are the options for a PromQL query.

type QueryableCreator

type QueryableCreator func(
	deduplicate bool,
	replicaLabels []string,
	storeDebugMatchers [][]*labels.Matcher,
	maxResolutionMillis int64,
	partialResponse,
	enableQueryPushdown,
	skipChunks bool,
	shardInfo *storepb.ShardInfo,
	seriesStatsReporter seriesStatsReporter,
) storage.Queryable

QueryableCreator returns implementation of promql.Queryable that fetches data from the proxy store API endpoints. If deduplication is enabled, all data retrieved from it will be deduplicated along all replicaLabels by default. When the replicaLabels argument is not empty it overwrites the global replicaLabels flag. This allows specifying replicaLabels at query time. maxResolutionMillis controls downsampling resolution that is allowed (specified in milliseconds). partialResponse controls `partialResponseDisabled` option of StoreAPI and partial response behavior of proxy.

func NewQueryableCreator

func NewQueryableCreator(
	logger log.Logger,
	reg prometheus.Registerer,
	proxy storepb.StoreServer,
	maxConcurrentSelects int,
	selectTimeout time.Duration,
) QueryableCreator

NewQueryableCreator creates QueryableCreator. NOTE(bwplotka): Proxy assumes to be replica_aware, see thanos.store.info.StoreInfo.replica_aware field.
