Testing whether a connection is still alive.\n1. Verifying the server's ability to serve data - an error is returned when this isn't the case (for example, during load from persistence data or accessing a stale replica).\n1. Measuring latency.\n\nIf the client is subscribed to a channel or a pattern, it will instead return a\nmulti-bulk string with `PONG` in the first position and an empty bulk string in the second\nposition, unless an argument is provided, in which case it returns a copy\nof the argument."
