Get Number of Active Connections in Redis

Redis is a high-performance, in-memory data store that efficiently handles multiple client connections. Monitoring active connections in Redis is crucial for performance tuning and debugging. Keeping track of these connections is essential to ensure that the application is functioning optimally and not exceeding resource limits. This tutorial explains how to get the number of active connections in Redis.

To quickly check the number of active connections, use the INFO command. The grep command can be used to filter the relevant output:

redis-cli INFO | grep connected_clients

Example output:

connected_clients:3

For more detailed information about each client connected to Redis, use the CLIENT LIST command:

redis-cli CLIENT LIST

Example output:

id=61 addr=127.0.0.1:43372 laddr=127.0.0.1:6379 fd=12 ...
id=62 addr=127.0.0.1:43380 laddr=127.0.0.1:6379 fd=13 ...
id=65 addr=127.0.0.1:58500 laddr=127.0.0.1:6379 fd=14 ...
