Functions

func SetupLogger

func SetupLogger(c *config.Config, opts ...Opt)

SetupLogger configures the global instance of zerolog.Logger using configuration from config.Config. Configuration can be further overwritten by providing custom options as arguments. SetupLogger uses "log.*" configuration keys. Each of the available log outputs (console, file, gelf) can be configured separately by providing "log.console.*", "log.file.*" and "log.gelf.*" keys. By default, only the "console" output is enabled, and is using "text" format, Global logging level can be configured with "log.level" config key, by default it set to "info".

Types

type Config

type Config struct {
	// Console is an instance of ConsoleConfig..
	Console ConsoleConfig

	// File is an instance of FileConfig.
	File FileConfig

	// Gelf is an instance of GelfConfig.
	Gelf GelfConfig
	// contains filtered or unexported fields
}

Config represents a configuration of the global logger.

type ConsoleConfig

type ConsoleConfig struct {
	// Enabled decides whether this output should be enabled or not.
	Enabled bool

	// Colors decides whether logging output should be colored or not.
	Colors bool

	// Format is a format of this output. It could be either "text" or "json".
	Format string
}

ConsoleConfig represents a configuration for console output. This output is emitted to os.Stderr.

type FileConfig

type FileConfig struct {
	// Enabled decides whether this output should be enabled or not.
	Enabled bool

	// Location is a path to the output file.
	Location string

	// Format is a format of this output. It could be either "text" or "json".
	Format string
}

FileConfig represents a configuration for file output. This output is emitted to a file.

type GelfConfig

type GelfConfig struct {
	// Enabled decides whether this output should be enabled or not.
	Enabled bool

	// Address is an address of the UDP socket in format HOST:PORT, for example: localhost:2000.
	Address string
}

GelfConfig represents a configuration for gelf output. This output is emitted to a UDP socket.
