Configuration

# Logging settings (docs: https://roadrunner.dev/docs/beep-beep-logging)
logs:
  # Logging mode can be "development", "production" or "raw". Do not forget to change this value for production environment.
  #
  # Development mode (which makes DPanicLevel logs panic), uses a console encoder, writes to standard error, and
  # disables sampling. Stacktraces are automatically included on logs of WarnLevel and above.
  #
  # Default: "development"
  mode: development

  # Logging level can be "panic", "error", "warn", "info", "debug".
  #
  # Default: "debug"
  level: debug

  # Encoding format can be "console" or "json" (last is preferred for production usage).
  #
  # Default: "console"
  encoding: console

  # Output can be file (eg.: "/var/log/rr_errors.log"), "stderr" or "stdout".
  #
  # Default: "stderr"
  output: stderr

  # Errors only output can be file (eg.: "/var/log/rr_errors.log"), "stderr" or "stdout".
  #
  # Default: "stderr"
  err_output: stderr

  # You can configure each plugin log messages individually (key is plugin name, and value is logging options in same
  # format as above).
  #
  # Default: <empty map>
  channels:
    http:
      mode: development
      level: panic
      encoding: console
      output: stdout
      err_output: stderr
    server:
      mode: production
      level: info
      encoding: json
      output: stdout
      err_output: stdout
    rpc:
      mode: raw
      level: debug
      encoding: console
      output: stderr
      err_output: stdout

Minimal dependencies:

1. Config plugin to read and populate plugin's configuration.

Worker sample:

<?php

require __DIR__ . '/vendor/autoload.php';

// Create a new Worker from global environment
$worker = \Spiral\RoadRunner\Worker::create();

while ($data = $worker->waitPayload()) {
    // Received Payload
    var_dump($data);

    // Respond Answer
    $worker->respond(new \Spiral\RoadRunner\Payload('DONE'));
}

Tips:

1. Use development logger mode only for the dev. It uses more resources even with panic level and not suitable for the production.
2. You can configure log parameters for the every plugin you use (see: channels in the configuration)

Functions

func ColoredLevelEncoder

func ColoredLevelEncoder(level zapcore.Level, enc zapcore.PrimitiveArrayEncoder)

ColoredLevelEncoder colorizes log levels.

func ColoredNameEncoder

func ColoredNameEncoder(s string, enc zapcore.PrimitiveArrayEncoder)

ColoredNameEncoder colorizes service names.

Types

type ChannelConfig

type ChannelConfig struct {
	// Dedicated channels per logger. By default logger allocated via named logger.
	Channels map[string]Config `mapstructure:"channels"`
}

ChannelConfig configures loggers per channel.

type Config

type Config struct {
	// Mode configures logger based on some default template (development, production, off).
	Mode Mode `mapstructure:"mode"`

	// Level is the minimum enabled logging level. Note that this is a dynamic
	// level, so calling ChannelConfig.Level.SetLevel will atomically change the log
	// level of all loggers descended from this config.
	Level string `mapstructure:"level"`

	// Logger line ending. Default: "\n" for the all modes except production
	LineEnding string `mapstructure:"line_ending"`

	// Encoding sets the logger's encoding. InitDefault values are "json" and
	// "console", as well as any third-party encodings registered via
	// RegisterEncoder.
	Encoding string `mapstructure:"encoding"`

	// Output is a list of URLs or file paths to write logging output to.
	// See Open for details.
	Output []string `mapstructure:"output"`

	// ErrorOutput is a list of URLs to write internal logger errors to.
	// The default is standard error.
	//
	// Note that this setting only affects internal errors; for sample code that
	// sends error-level logs to a different location from info- and debug-level
	// logs, see the package-level AdvancedConfiguration example.
	ErrorOutput []string `mapstructure:"errorOutput"`

	// File logger options
	FileLogger *FileLoggerConfig `mapstructure:"file_logger_options"`
}

func (*Config) BuildLogger

func (cfg *Config) BuildLogger() (*zap.Logger, error)

BuildLogger converts config into Zap configuration.

func (*Config) InitDefault

func (cfg *Config) InitDefault()

InitDefault Initialize default logger

type FileLoggerConfig

type FileLoggerConfig struct {
	// Filename is the file to write logs to.  Backup log files will be retained
	// in the same directory.  It uses <processname>-lumberjack.log in
	// os.TempDir() if empty.
	LogOutput string `mapstructure:"log_output"`

	// MaxSize is the maximum size in megabytes of the log file before it gets
	// rotated. It defaults to 100 megabytes.
	MaxSize int `mapstructure:"max_size"`

	// MaxAge is the maximum number of days to retain old log files based on the
	// timestamp encoded in their filename.  Note that a day is defined as 24
	// hours and may not exactly correspond to calendar days due to daylight
	// savings, leap seconds, etc. The default is not to remove old log files
	// based on age.
	MaxAge int `mapstructure:"max_age"`

	// MaxBackups is the maximum number of old log files to retain.  The default
	// is to retain all old log files (though MaxAge may still cause them to get
	// deleted.)
	MaxBackups int `mapstructure:"max_backups"`

	// Compress determines if the rotated log files should be compressed
	// using gzip. The default is not to perform compression.
	Compress bool `mapstructure:"compress"`
}
