+If the logger does not receive a successful response from the server, it tries to send it again in the period set in `options` (`options.retryTimeout`) or the default `BACKOFF_PERIOD`. It makes three (or `RETRY_TIMES`) attempts to resend the logs. If none of the attempts was successful, the failed logs will be preserved and attempted to send with the next request. The size of the retry buffer that saves logs that failed to send and the retry timeout are configurable via:
 
 ``` javascript
 var options = {
     failedBufRetentionLimit: 10000000 // bytes
     retryTimeout: 3000 // milliseconds
+    retryTimes: 5
 };
 
 var logger = Logger.setupDefaultLogger(apikey, options);
