Redis Connection: PING

Redis PING Command

Redis PING command is used to check whether a server connection is still alive, or to measure latency.

Here are some common uses and scenarios for the "PING" command:

• Connection Testing: Checks if the Redis server is reachable and responsive by sending a simple request and expecting a response.
• Health Monitoring: Monitors the health and status of the Redis server, ensuring it is running and capable of handling requests.
• Latency Measurement: Measures the round-trip time between the client and the server, helping to assess the network latency.
• Keep-Alive: Keeps the connection to the Redis server alive during idle periods by sending periodic PING commands.
