RedisMetricredis.db.keys
Number of keys in the databaseDimensions:None
Summary
Current count of all keys stored in a specific Redis database (0-15 by default). This fundamental metric indicates dataset size and growth trends. Rapid growth may signal data accumulation issues, particularly if keys lack TTL settings. Compare across databases to identify which logical database (e.g., db0, db1) consumes the most keyspace. Use with memory metrics to calculate average key size and identify memory efficiency issues.

Expiring Keys Without TTL Monitoring Causes Memory Leakswarning
When redis.persist count is high relative to redis.db.expires, many keys lack TTLs and will accumulate indefinitely, causing memory growth. redis.keyspace.avg_ttl can indicate if TTL values are too long for workload patterns.
