Functions

func New

func New(vp *viper.Viper) *cobra.Command

New observer command.

Types

type IOReaderObserver

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

IOReaderObserver implements ObserverClient interface. It reads flows in jsonpb format from an io.Reader.

func NewIOReaderObserver

func NewIOReaderObserver(reader io.Reader) *IOReaderObserver

NewIOReaderObserver reads flows in jsonpb format from an io.Reader and returns a IOReaderObserver that implements the ObserverClient interface.

func (*IOReaderObserver) GetAgentEvents

func (o *IOReaderObserver) GetAgentEvents(_ context.Context, _ *observerpb.GetAgentEventsRequest, _ ...grpc.CallOption) (observerpb.Observer_GetAgentEventsClient, error)

GetAgentEvents is not implemented, and will throw an error if used.

func (*IOReaderObserver) GetDebugEvents

func (o *IOReaderObserver) GetDebugEvents(_ context.Context, _ *observerpb.GetDebugEventsRequest, _ ...grpc.CallOption) (observerpb.Observer_GetDebugEventsClient, error)

GetDebugEvents is not implemented, and will throw an error if used.

func (*IOReaderObserver) GetFlows

func (o *IOReaderObserver) GetFlows(ctx context.Context, in *observerpb.GetFlowsRequest, _ ...grpc.CallOption) (observerpb.Observer_GetFlowsClient, error)

GetFlows returns flows

func (*IOReaderObserver) GetNamespaces

func (o *IOReaderObserver) GetNamespaces(_ context.Context, _ *observerpb.GetNamespacesRequest, _ ...grpc.CallOption) (*observerpb.GetNamespacesResponse, error)

GetNamespaces is not implemented, and will throw an error if used.

func (*IOReaderObserver) GetNodes

func (o *IOReaderObserver) GetNodes(_ context.Context, _ *observerpb.GetNodesRequest, _ ...grpc.CallOption) (*observerpb.GetNodesResponse, error)

GetNodes is not implemented, and will throw an error if used.

func (*IOReaderObserver) ServerStatus

func (o *IOReaderObserver) ServerStatus(_ context.Context, _ *observerpb.ServerStatusRequest, _ ...grpc.CallOption) (*observerpb.ServerStatusResponse, error)

ServerStatus is not implemented, and will throw an error if used.
