Types

type Callback

type Callback trace.EventCallback

Callback provides a custom callback function which is called for each tracing event.

func (Callback) ApplyTracer

func (cb Callback) ApplyTracer(t *g.Tracer)

type Capture

type Capture struct {
	*g.Capture
}

Capture will write Tracepoints as fake packets to the capture.

Checkout the included Lua-based WireShark dissector to decode the fake tracing event packets.

Start WireShark with the following options to load the dissector:

wireshark -Xlua_script:dissector.lua

See ./dissector/dissector.lua
