Each entry in the map represent a single engine.\n   Engine map contains statistics about the engine like number of functions and number of libraries.\n\nYou can use this command to inspect the invocation of a long-running function and decide whether kill it with the [`FUNCTION KILL`](https://redis.io/docs/latest/commands/function-kill) command.\n\nFor more information please refer to [Introduction to Redis Functions](https://redis.io/docs/latest/develop/programmability/functions-intro)."
