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.

Types

type CircularBufferLoggingManager

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

CircularBufferLoggingManager implements logging to circular fixed size buffer.

func NewCircularBufferLoggingManager

func NewCircularBufferLoggingManager() *CircularBufferLoggingManager

func (*CircularBufferLoggingManager) ServiceLog

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

ServiceLog 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
