The CLIENT SETINFO command sets client library name and version information that will be shown in CLIENT LIST and CLIENT INFO commands. This helps identify which client library is being used and is useful for debugging and monitoring.

​
Arguments

​
attribute
'LIB-NAME' | 'LIB-VER'
required
The attribute to set:
  • LIB-NAME or lib-name: Library name
  • LIB-VER or lib-ver: Library version
​
value
string
required
The value to set for the attribute.

​
Response

Returns OK if the attribute was successfully set.
// Set the library name
await redis.clientSetInfo("LIB-NAME", "redis-js");
// Returns: "OK"

​
Use Cases

  • Debugging: Identify which client library version is being used
  • Monitoring: Track different client libraries connecting to Redis
  • Analytics: Understand client library distribution across connections
  • Support: Quickly identify client versions when troubleshooting issues

​
Viewing Client Information

After setting client info, you can view it using the CLIENT LIST command: 
// Set client information
await redis.clientSetInfo("LIB-NAME", "redis-js");
await redis.clientSetInfo("LIB-VER", "1.0.0");

// View all clients (if you have access to CLIENT LIST)
// The output will include lib-name and lib-ver fields

​
Best Practices

  1. Set on Connection: Set client info immediately after establishing a connection
  2. Include Version: Always set both library name and version
  3. Use Descriptive Names: Make library names easily identifiable
  4. Version Format: Use semantic versioning (e.g., “1.2.3”)
  5. Include Context: Add wrapper or framework info if applicable
This command is available in Redis 7.2.0 and later. The attribute names are case-insensitive and will be normalized to uppercase.
