var Emitters = make(map[string]Emitter)

Emitters is the registry of Emitter implementers

Functions

func Emit 

func Emit(emitter Emitter, logMessage string)

Emit is launched as a goroutine for individual log lines to be sent concurrently. When it receives a line, it tries to decode it from JSON. If that succeeds, meaning it's already a structured object, we pass it along unmodified. If not, we wrap it in a basic ECS structure.

func Register 

func Register(emitterType string, emitter Emitter)

Register will make note of new types of Emitters

Types

type Emitter 

type Emitter interface {
	Setup()
	HandleLogMessage(jsonSerializeable interface{}) error
	Cleanup() error
}

An Emitter defines how to ship a log message to a log service.

type Message 

type Message struct {
	ECSVersion string            `json:"ecs.version"`
	Timestamp  time.Time         `json:"@timestamp"`
	Labels     map[string]string `json:"labels"`
	Tags       []string          `json:"tags"`
	Message    string            `json:"message"`
}

A Message is a structured log message - only used if the log message we consume from the subprocess is not already structured
