Functions

func NewInProcessClient

func NewInProcessClient(t testing.TB, name string, client storepb.StoreClient, extLset labels.Labels) store.Client

func ParseEval

func ParseEval(lines []string, i int) (int, *evalCmd, error)

ParseEval parses eval statements.

func ParseLoad

func ParseLoad(lines []string, i int) (int, *loadCmd, error)

ParseLoad parses load statements.

Types

type EndpointSet

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

func NewEndpointSet(
	logger log.Logger,
	reg *prometheus.Registry,
	endpointSpecs func() []*GRPCEndpointSpec,
	dialOpts []grpc.DialOption,
	unhealthyEndpointTimeout time.Duration,
) *EndpointSet

NewEndpointSet returns a new set of Thanos APIs.

func (*EndpointSet) Close

func (e *EndpointSet) Close()

func (*EndpointSet) GetEndpointStatus

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

func (*EndpointSet) GetExemplarsStores

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

GetExemplarsStores returns a list of all active exemplars stores.

func (*EndpointSet) GetMetricMetadataClients

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

GetMetricMetadataClients returns a list of all active metadata clients.

func (*EndpointSet) GetRulesClients

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

GetRulesClients returns a list of all active rules clients.

func (*EndpointSet) GetStoreClients

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

GetStoreClients returns a list of all active stores.

func (*EndpointSet) GetTargetsClients

func (e *EndpointSet) GetTargetsClients() []targetspb.TargetsClient

GetTargetsClients returns a list of all active targets clients.

func (*EndpointSet) Update

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

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

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

func NewGRPCEndpointSpec

func NewGRPCEndpointSpec(addr string, isStrictStatic bool) *GRPCEndpointSpec

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

func (*GRPCEndpointSpec) Addr

func (es *GRPCEndpointSpec) Addr() string

func (*GRPCEndpointSpec) IsStrictStatic

func (es *GRPCEndpointSpec) IsStrictStatic() bool

IsStrictStatic returns true if the endpoint has been statically defined and it is under a strict mode.

func (*GRPCEndpointSpec) Metadata

func (es *GRPCEndpointSpec) Metadata(ctx context.Context, client *endpointClients) (*endpointMetadata, error)

Metadata method for gRPC endpoint tries to call InfoAPI exposed by Thanos components until context timeout. If we are unable to get metadata after that time, we assume that the host is unhealthy and return error.

type QueryableCreator

type QueryableCreator func(deduplicate bool, replicaLabels []string, storeDebugMatchers [][]*labels.Matcher, maxResolutionMillis int64, partialResponse, enableQueryPushdown, skipChunks bool) 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.
