Types

type FlowTracer

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

FlowTracer reads and forwards the Flows from the Transmission Control, for a given interface.

func NewFlowTracer

func NewFlowTracer(iface string, sampling uint32) *FlowTracer

NewFlowTracer fo a given interface type

func (*FlowTracer) Register

func (m *FlowTracer) Register() error

Register and links the eBPF tracer into the system. The program should invoke Unregister before exiting.

func (*FlowTracer) Trace

func (m *FlowTracer) Trace(ctx context.Context, forwardFlows chan<- *flow.Record)

Trace and forward the read flows until the passed context is Done

func (*FlowTracer) Unregister

func (m *FlowTracer) Unregister() error

Unregister the eBPF tracer from the system.
