getStatistics #
Without argument, retrieves the last statistic frame in an array: When providing a timestamp, retrieves all frames recorded after that timestamp: Kuzzle server monitors active connections, and ongoing/completed/failed requests.
This method returns either the last statistics frame, or a set of frames starting from a provided timestamp.
getStatistics([timestamp], [options], callback) #
Arguments | Type | Description |

.then(statistics => {
});
