Overview

Package logging presents interface (and its implementation sets) of a structured logger for Go. The interface is focused on the GELF Payload Specification logging format (http://docs.graylog.org/en/2.4/pages/gelf.html), but provides support for the universal use of logging. Recommendations for the implementation of GELF Payload Specification field formatting: - "version" - adds the sender of the message to the log. - "host" - adds the used hook (for example, GrayLog Hook). - "short_message" - adds the sender of the message to the log. - "full_message" - adds the sender of the message to the log. - "timestamp" - adds logging. - "level" - adds the sender of the message to the log. - "facility" - adds the sender of the message to the log. - "line" - adds a used hook (for example, GrayLog Hook). - "file" - adds a used hook (for example, GrayLog Hook). - additional fields - adds the sender of the message to the log.

Types

type Entry

type Entry interface {
	Debug(args ...interface{})
	Info(args ...interface{})
	Warning(args ...interface{})
	Error(args ...interface{})
	Fatal(args ...interface{})
	GracefulFatal(ctx context.Context)
	Panic(args ...interface{})
	Writer() *io.PipeWriter
	WithValues(v Values) Entry
	GetValues() Values
	FromContext(ctx context.Context) Entry
	NewContext(ctx context.Context) context.Context
}

Entry provides recording to logging.

type Logger

type Logger interface {
	Entry
	AddHooks(hooks ...interface{}) error
}

Logger provides logging functionality.

type Values

type Values map[string]interface{}

Values built in type for processing fields in context.
