Redis Slow Responses

Commands taking longer than usual to execute, indicating performance bottlenecks.
  1. Check Server Load and Memory Usage: Use commands like top or htop on the server to see if the CPU or memory is maxed out. For memory specifically related to Redis, you can use the Redis command INFO memory to see memory usage details.
  2. Analyze Slow Queries: Run the Redis command SLOWLOG GET to retrieve a list of slow operations. If the slowlog is empty, you might need to lower the slowlog threshold.
  3. Monitor Network Latency: Use tools like ping or traceroute from your application server to the Redis server to check for any network delays.
  4. Check for Blocked Clients: Execute INFO Clients to see if there are any clients listed as blocked, which might indicate issues with blocking commands or transactions taking too long.
  5. Evaluate Redis Configuration: Use CONFIG GET * to review current Redis configuration settings that might be impacting performance, such as maxmemory settings or eviction policies.
  6. Inspect Key Sizes and Types: Use redis-cli --bigkeys or MEMORY USAGE <key> for specific keys to identify if particular keys are consuming an unusual amount of memory, which could affect performance.
  7. Review Persistence Options: If using RDB or AOF persistence, check the configuration and performance impact by examining the INFO Persistence output. Large save operations or frequent AOF rewrites could impact performance.
  8. Use the MONITOR Command Sparingly: The MONITOR command allows you to see all commands being executed in real-time but can significantly reduce performance. Use it briefly to spot immediate issues.
  9. Evaluate Current Connections: With CLIENT LIST or INFO Clients, you can see all current connections to Redis and possibly identify unexpected or excessive connections.
  10. Check Redis Server Logs: Look at the Redis server logs for any warnings or errors that might indicate issues affecting performance.
