Redis Error Logs

Frequent error messages in Redis logs indicating problems like memory fragmentation, failed replication, or persistence errors.
  1. Check the Redis log file immediately. Use tail -f /var/log/redis/redis-server.log to view the latest entries in real-time.
  2. If you see memory-related errors, run info memory in the Redis CLI to check memory usage details.
  3. For connection issues, use client list to see current connections and info stats to check total connections received and connection errors.
  4. If the error log mentions slow commands, execute slowlog get to retrieve a list of slow commands and investigate those specific operations.
  5. For replication issues, run info replication to check the status of your Redis replication setup.
  6. Use monitor to watch commands being executed in real-time for a short period if you suspect unexpected behavior, but be cautious as this can affect performance.
  7. If CPU related errors appear, use info cpu to check Redis CPU usage statistics.
  8. For configuration issues, inspect the Redis configuration file typically found at /etc/redis/redis.conf or run CONFIG GET * to see current configuration settings in the CLI.
  9. In case of persistent errors or data integrity concerns, initiate a manual backup with bgsave, and then inspect the lastsave command to ensure it was successful.
  10. If you suspect a specific key or pattern is causing issues, use scan with a match option to safely iterate keys and debug object key to inspect problematic keys without affecting performance.
