How to read the latest cache information in redis

The Redis MONITOR command can read Redis cache information in real time, providing information about executed commands, keys, values, etc. Steps: 1. Connect to the Redis server. 2. Execute the "MONITOR" command. 3. The server will send Redis command execution information in real time. 4. Each line in the event stream represents an executed command, including timestamp, client address, command name and parameters. 5. Press "Ctrl C" to stop monitoring.

Use the MONITOR command to read Redis cache information in real time

The MONITOR command in Redis allows the client to subscribe to all in real time Redis command execution information. This allows us to monitor recent cache activity on the server.

Usage steps:

1. Connect to the Redis server: Use redis-cli or other Redis client to connect to the server.
2. Execute the MONITOR command: Type the "MONITOR" command and press the Enter key.

<code>127.0.0.1:6379> MONITOR</code>

3. Listening event stream: The server will start sending information about the executed Redis command. The event stream will display commands, keys, values, and other relevant information.

Example events:

<code>1568962305.065722 [127.0.0.1:32768] "set" "mykey" "myvalue"</code>

Parse the event stream:

Each line in the event stream represents a Redis command execution. Each line begins with a timestamp, followed by the client address and port number where the command was executed. Next is the name of the command, followed by the parameters of the command.

Example:

• The "set" command sets the key "mykey" to the value "myvalue".
• The "get" command gets the value of the key "mykey".
• The "del" command deletes the key "mykey".

Stop listening:

To stop listening to the event stream, press "Ctrl C" in the terminal window.
