const (
	// LostEventSourceUnspec indicates an event has been lost at an unknown
	// source
	LostEventSourceUnspec = iota
	// LostEventSourcePerfRingBuffer indicates an event has been lost because
	// the perf event ring buffer was not read before it was overwritten.

Types

type AgentEvent

type AgentEvent struct {
	// Type is a monitorAPI.MessageType* value
	Type int
	// Message is the agent message, e.g. accesslog.LogRecord, monitorAPI.AgentNotify
	Message interface{}
}

AgentEvent is any agent event

type LostEvent

type LostEvent struct {
	// Source is where the events were dropped
	Source int
	// NumLostEvents is the number of events lost
	NumLostEvents uint64
	// CPU is the cpu number if for events lost in the perf ring buffer
	CPU int
}

LostEvent indicates that a number of events were lost at the indicated source

type MonitorEvent

type MonitorEvent struct {
	// Timestamp when the event was received by the consumer
	Timestamp time.Time
	// NodeName where the event occurred
	NodeName string
	// Payload is one of: AgentEvent, PerfEvent or LostEvent
	Payload interface{}
}

MonitorEvent is the top-level type for all events consumed by the observer

type PerfEvent

type PerfEvent struct {
	// Data is the raw data payload of the perf event
	Data []byte
	// CPU is the cpu number on which the perf event occurred
	CPU int
}

PerfEvent is a raw event obtained from a BPF perf ring buffer
