Constants

const (
	// Some logs are tiny, no need to reserve too much memory.
	InitialCapacity = 16384
	// Cap each log at 1M.
	MaxCapacity = 1048576
	// Safety gap to avoid buffer overruns.
	SafetyGap = 2048
)

These constants should some day move to config.

Functions

func NewJSONLines

func NewJSONLines(endpoint *url.URL) runtime.LogSender

NewJSONLines returns log sender that sends logs in JSON over TCP (newline-delimited) or UDP (one message per packet).

Types

type CircularBufferLoggingManager

type CircularBufferLoggingManager struct {
	// contains filtered or unexported fields
}

CircularBufferLoggingManager implements logging to circular fixed size buffer.

func NewCircularBufferLoggingManager

func NewCircularBufferLoggingManager(fallbackLogger *log.Logger) *CircularBufferLoggingManager

NewCircularBufferLoggingManager initializes new CircularBufferLoggingManager.

func (*CircularBufferLoggingManager) ServiceLog

func (manager *CircularBufferLoggingManager) ServiceLog(id string) runtime.LogHandler

ServiceLog implements runtime.LoggingManager interface.

func (*CircularBufferLoggingManager) SetSenders

func (manager *CircularBufferLoggingManager) SetSenders(senders []runtime.LogSender) []runtime.LogSender

SetSenders implements runtime.LoggingManager interface.

type FileLoggingManager

type FileLoggingManager struct {
	// contains filtered or unexported fields
}

FileLoggingManager implements simple logging to files.

func NewFileLoggingManager

func NewFileLoggingManager(logDirectory string) *FileLoggingManager

NewFileLoggingManager initializes new FileLoggingManager.

func (*FileLoggingManager) ServiceLog

func (manager *FileLoggingManager) ServiceLog(id string) runtime.LogHandler

ServiceLog implements runtime.LoggingManager interface.

func (*FileLoggingManager) SetSenders

func (manager *FileLoggingManager) SetSenders([]runtime.LogSender) []runtime.LogSender

SetSenders implements runtime.LoggingManager interface (by doing nothing).

type NullLoggingManager

type NullLoggingManager struct{}

NullLoggingManager sends all the logs to /dev/null.

func NewNullLoggingManager

func NewNullLoggingManager() *NullLoggingManager

NewNullLoggingManager initializes NullLoggingManager.

func (*NullLoggingManager) ServiceLog

func (*NullLoggingManager) ServiceLog(id string) runtime.LogHandler

ServiceLog implements LoggingManager.

func (*NullLoggingManager) SetSenders

func (*NullLoggingManager) SetSenders([]runtime.LogSender) []runtime.LogSender

SetSenders implements runtime.LoggingManager interface (by doing nothing).
