Package statsd is a simple and efficient StatsD client. Use options to configure the Client: target host/port, sampling rate, tags, etc. Whenever you want to use different options (e.g. other tags, different sampling rate), you should use the Clone() method of the Client. Because when cloning a Client, the same connection is reused so this is way cheaper and more efficient than creating another Client using New(). Client's methods buffer metrics. The buffer is flushed when either: The background goroutine can be disabled using the FlushPeriod(0) option. Buffering can be disabled using the MaxPacketSize(0) option.
