How to watch Redis activity

Solution

Run:

$ redis-cli

Then, type MONITOR.

Explanation

redis-cli – the Redis command line interface. It has an interactive REPL (Read Eval Print Loop) mode where the user types Redis commands and received replies, and a command mode where redis-cli is executed with additional arguments and the reply is printed to the standard output. We use it here in the interactive mode.

Similarly to the Pub/Sub mode, the monitoring mode is entered automatically once you use the MONITOR command. All commands received by the active Redis instance will be printed to the standard output:

$ redis-cli MONITOR
OK
