Types

type Config 

type Config struct {
	// PrintLogs enables printing of logs to STDERR.
	PrintLogs bool

	// Topic sets a namespace for messages.
	Topic string

	// NsqdURL is the URL to http service of an nsqd daemon
	NsqdURL string
}

Config provides data necessary to start NSQ session. NSQ is a distributed messaging service.

type LogNSQ 

type LogNSQ struct {
	Config
	*nsq.Producer
}

LogNSQ creates a "producer" to the nsqd service. The producer is able to publish messages to nsqd. It cannot consume the messages. If the same config is used for many different apps, all of them are able to contribute their logs to the same namespace using nsqd.

func New 

func New(cfg Config) (l *LogNSQ, err error)

New Creates a new LogNSQ instance. If creation of "producer" failed, it returns an error.

func (*LogNSQ) Write 

func (l *LogNSQ) Write(bs []byte) (n int, err error)

Write takes a slice of bytes and publishes it to STDERR as well as to nsqd service. It uses Topic given in the config.
