PING

Returns PONG if no argument is provided, otherwise return a copy of the argument as a bulk. This command is useful for:

  1. Testing whether a connection is still alive.
  2. Verifying the server's ability to serve data - an error is returned when this isn't the case (e.g., during load from persistence or accessing a stale replica).
  3. Measuring latency.

If the client is subscribed to a channel or a pattern, it will instead return a multi-bulk with a "pong" in the first position and an empty bulk in the second position, unless an argument is provided in which case it returns a copy of the argument.

Examples

{{% redis-cli %}} PING

PING "hello world" {{% /redis-cli %}}
