Functions

func SendAlert

func SendAlert(channel, username, title, color, text string, settings LogSettings) (err error)

SendAlert sends a notification to the specified slack channel

func SetLogLevel

func SetLogLevel(level int)

SetLogLevel configures the application's log level

func SetLogger

func SetLogger(l Logger)

SetLogger sets the current logger

Types

type LogSettings

type LogSettings interface {
	GetSlackEnabled() bool
	GetHTTPClient() (client *http.Client)
	GetAppName() string
}

LogSettings interface to be implemented by other project settings.

type Logger

type Logger interface {
	Debug(v ...interface{})
	Debugf(format string, v ...interface{})
	Info(v ...interface{})
	Infof(format string, v ...interface{})
	Error(v ...interface{})
	Errorf(format string, v ...interface{})
	Fatal(v ...interface{})
	Fatalf(format string, v ...interface{})
	Print(v ...interface{})
	SetLevel(level int)
	GetLevel() int
	LogToSlack(webHook, title, text string, logSettings LogSettings)
	LogErrorToSlack(webHook, title, text string, logSettings LogSettings)
}

Logger presents a common interface for logger

func GetLogger

func GetLogger() Logger

GetLogger returns the current logger defined for the service

type SimpleLogger

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

SimpleLogger is the standar logger implementation

func NewSimpleLogger

func NewSimpleLogger() (sl *SimpleLogger)

NewSimpleLogger creates a new instance of SimpleLogger.

func (*SimpleLogger) Debug

func (sl *SimpleLogger) Debug(v ...interface{})

Debug prints the arguments to the debug logger.

func (*SimpleLogger) Debugf

func (sl *SimpleLogger) Debugf(format string, v ...interface{})

Debugf prints the arguments to the debug logger. Arguments are handled like in fmt.Printf.

func (*SimpleLogger) Error

func (sl *SimpleLogger) Error(v ...interface{})

Error prints the arguments to the error logger.

func (*SimpleLogger) Errorf

func (sl *SimpleLogger) Errorf(format string, v ...interface{})

Errorf prints the arguments to the error logger. Arguments are handled like in fmt.Printf.

func (*SimpleLogger) Fatal

func (sl *SimpleLogger) Fatal(v ...interface{})

Fatal prints the arguments to the error logger, followed by a call to os.Exit(1).

func (*SimpleLogger) Fatalf

func (sl *SimpleLogger) Fatalf(format string, v ...interface{})

Fatalf prints the arguments to the error logger, followed by a call to os.Exit(1). Arguments are handled like in fmt.Printf.

func (*SimpleLogger) GetLevel

func (sl *SimpleLogger) GetLevel() int

GetLevel returns the current log level

func (*SimpleLogger) Info

func (sl *SimpleLogger) Info(v ...interface{})

Info prints the arguments to the info logger.

func (*SimpleLogger) Infof

func (sl *SimpleLogger) Infof(format string, v ...interface{})

Infof prints the arguments to the info logger. Arguments are handled like in fmt.Printf.

func (*SimpleLogger) LogErrorToSlack

func (sl *SimpleLogger) LogErrorToSlack(webHook, title, text string, logSettings LogSettings)

LogErrorToSlack sends a message formatted as error to the configured channel, if it's enabled

func (*SimpleLogger) LogToSlack

func (sl *SimpleLogger) LogToSlack(webHook, title, text string, logSettings LogSettings)

LogToSlack sends a message to the configured channel, if it's enabled

func (*SimpleLogger) Print

func (sl *SimpleLogger) Print(v ...interface{})

Print prints the arguemtns to the info logger. It's good for standar logger compatibility

func (*SimpleLogger) SetLevel

func (sl *SimpleLogger) SetLevel(level int)

SetLevel sets the log level (0=ERROR, 1=INFO, 2=DEBUG)
