Variables

var AWSCloudWatchEndpoint string

AWSCloudWatchEndpoint allows you to mock cloudwatch client by redirecting requests to a local proxy

Functions

func CloseZerolog

func CloseZerolog()

CloseZerolog closes properly the zerolog, if needed

func InitZerolog

func InitZerolog(
	loggingConf LoggingConfiguration, cloudWatchConf CloudWatchConfiguration, sentryConf SentryLoggingConfiguration,
	kafkazerologConf KafkaZerologConfiguration, additionalWriters ...io.Writer,
) error

InitZerolog initializes zerolog with provided configs to use proper stdout and/or CloudWatch logging

Types

type CloudWatchConfiguration

type CloudWatchConfiguration struct {
	AWSAccessID             string `mapstructure:"aws_access_id" toml:"aws_access_id"`
	AWSSecretKey            string `mapstructure:"aws_secret_key" toml:"aws_secret_key"`
	AWSSessionToken         string `mapstructure:"aws_session_token" toml:"aws_session_token"`
	AWSRegion               string `mapstructure:"aws_region" toml:"aws_region"`
	LogGroup                string `mapstructure:"log_group" toml:"log_group"`
	StreamName              string `mapstructure:"stream_name" toml:"stream_name"`
	CreateStreamIfNotExists bool   `mapstructure:"create_stream_if_not_exists" toml:"create_stream_if_not_exists"`

	// enable debug logs for debugging aws client itself
	Debug bool `mapstructure:"debug" toml:"debug"`
}

CloudWatchConfiguration represents configuration of CloudWatch logger

type KafkaZerologConfiguration

type KafkaZerologConfiguration struct {
	Broker   string `mapstructure:"broker" toml:"broker"`
	Topic    string `mapstructure:"topic" toml:"topic"`
	CertPath string `mapstructure:"cert_path" toml:"cert_path"`
	Level    string `mapstructure:"level" toml:"level"`
}

KafkaZerologConfiguration represetns the configuration for sending log messages to a Kafka topic

type LoggingConfiguration

type LoggingConfiguration struct {
	// Debug enables pretty colored logging
	Debug     bool `mapstructure:"debug" toml:"debug"`
	UseStderr bool `mapstructure:"use_stderr" toml:"use_stderr"`

	// LogLevel sets logging level to show. Possible values are:
	// "debug"
	// "info"
	// "warn", "warning"
	// "error"
	// "fatal"
	//
	// logging level won't be changed if value is not one of listed above
	LogLevel string `mapstructure:"log_level" toml:"log_level"`

	// LoggingToCloudWatchEnabled enables logging to CloudWatch
	// (configuration for CloudWatch is in CloudWatchConfiguration)
	LoggingToCloudWatchEnabled bool `mapstructure:"logging_to_cloud_watch_enabled" toml:"logging_to_cloud_watch_enabled"`

	// LoggingToSentryEnabled enables logging to Sentry
	// (configuration for Sentry is in SentryLoggingConfiguration)
	LoggingToSentryEnabled bool `mapstructure:"logging_to_sentry_enabled" toml:"logging_to_sentry_enabled"`

	// LoggingToKafkaEnabled enables logging to Kafka
	// (configuration for Kafka logging is in KafkaZerologConfiguration)
	LoggingToKafkaEnabled bool `mapstructure:"logging_to_kafka_enabled" toml:"logging_to_kafka_enabled"`
}

LoggingConfiguration represents configuration for logging in general

type SaramaZerologger

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

SaramaZerologger is a wrapper to make sarama log to zerolog those logs can be filtered by key "package" with value "sarama"

func (*SaramaZerologger) Print

func (logger *SaramaZerologger) Print(params ...interface{})

Print wraps print method

func (*SaramaZerologger) Printf

func (logger *SaramaZerologger) Printf(format string, params ...interface{})

Printf wraps printf method

func (*SaramaZerologger) Println

func (logger *SaramaZerologger) Println(v ...interface{})

Println wraps println method

type SentryLoggingConfiguration

type SentryLoggingConfiguration struct {
	SentryDSN string `mapstructure:"dsn" toml:"dsn"`
}

SentryLoggingConfiguration represents the configuration of Sentry logger

type WorkaroundForRHIOPS729

type WorkaroundForRHIOPS729 struct {
	io.Writer
}

WorkaroundForRHIOPS729 keeps only those fields that are currently getting their way to Kibana TODO: delete when RHIOPS-729 is fixed

func (WorkaroundForRHIOPS729) Write

func (writer WorkaroundForRHIOPS729) Write(bytes []byte) (int, error)
