sub.on("connect", redisConnectionHandler);
pub.on("end", redisEndHandler);
sub.on("end", redisEndHandler);
pub.on("error", redisErrorHandler);
sub.on("error", redisErrorHandler);

// force logger to run restify version. (default is express, forcing express is also legal)
log.forceLogger("restify");

// set the logging level threshold
log.setLoggingLevel("info");

// register names of custom fields
log.registerCustomFields(["node_version", "pid", "platform"])
