Types

type EventType

type EventType uint8

const (
	EventTypeHTTP EventType = iota + 1
	EventTypeGRPC
	EventTypeHTTPClient
	EventTypeGRPCClient
	EventTypeSQLClient
)

The following consts need to coincide with some C identifiers: EVENT_HTTP_REQUEST, EVENT_GRPC_REQUEST, EVENT_HTTP_CLIENT, EVENT_GRPC_CLIENT, EVENT_SQL_CLIENT

type IgnoreMode

type IgnoreMode uint8

const (
	IgnoreMetrics IgnoreMode = iota + 1
	IgnoreTraces
)

type PidInfo

type PidInfo struct {
	// HostPID is the PID as seen by the host (root cgroup)
	HostPID uint32
	// UserID is the PID as seen by the user space.
	// Might differ from HostPID if the process is in a different namespace/cgroup/container/etc.
	UserPID uint32
	// Namespace for the PIDs
	Namespace uint32
}

PidInfo stores different views of the PID of the process that generated the span

type Span

type Span struct {
	Type          EventType
	IgnoreSpan    IgnoreMode
	ID            uint64
	Method        string
	Path          string
	Route         string
	Peer          string
	Host          string
	HostPort      int
	Status        int
	ContentLength int64
	RequestStart  int64
	Start         int64
	End           int64
	ServiceID     svc.ID // TODO: rename to Service or ResourceAttrs
	TraceID       trace2.TraceID
	SpanID        trace2.SpanID
	ParentSpanID  trace2.SpanID
	Flags         uint8
	Pid           PidInfo
}

Span contains the information being submitted by the following nodes in the graph. It enables comfortable handling of data from Go.

func (*Span) Inside

func (s *Span) Inside(parent *Span) bool

func (*Span) Timings

func (s *Span) Timings() Timings

type Timings

type Timings struct {
	RequestStart time.Time
	Start        time.Time
	End          time.Time
}
