Types

type FileID

type FileID uint64

FileID is used for unique identifiers for files, and is required to be 64-bits due to the constraints imposed by the eBPF maps, unlike the larger FileID used outside the host agent.

func FileIDFromBytes

func FileIDFromBytes(b []byte) (FileID, error)

FileIDFromBytes parses a byte slice into the internal data representation for a file ID.

func FileIDFromLibpf

func FileIDFromLibpf(id libpf.FileID) FileID

FileIDFromLibpf truncates a libpf.FileID to be a host.FileID.

func (FileID) StringNoQuotes

func (fid FileID) StringNoQuotes() string

type Frame

type Frame struct {
	File          FileID
	Lineno        libpf.AddressOrLineno
	Type          libpf.FrameType
	ReturnAddress bool
}

type Trace

type Trace struct {
	Comm             string
	Executable       string
	Frames           []Frame
	Hash             TraceHash
	KTime            times.KTime
	PID              libpf.PID
	TID              libpf.PID
	APMTraceID       libpf.APMTraceID
	APMTransactionID libpf.APMTransactionID
	CPU              int
}

type TraceHash

type TraceHash uint64

TraceHash is used for unique identifiers for traces, and is required to be 64-bits due to the constraints imposed by the eBPF maps, unlike the larger TraceHash used outside the host agent.
