Redis: Complete Health Intelligence & Recommendations Engine

Redis Complete Health Intelligence (v0.33.3)

New Metrics (80+ total)

• Latency: p50, p99, p99.9 percentiles displayed + health-checked
• SLOWLOG: Fetches top slow queries via SLOWLOG GET with timestamp, duration, command
• Memory: RSS overhead ratio, allocator info, lazyfree pending objects
• Clients: Capacity % (connected/maxclients), input/output buffer sizes
• Persistence: Fork duration (latest_fork_usec), AOF size, rewrite status
• Replication: Lag bytes (slave vs master offset), backlog size
• Server: hz, arch_bits, cluster_enabled, pub/sub channels

New Health Checks (16 rules, was 8)

• p99 latency >10ms (-10), >1ms (-5)
• RSS ratio >2.0x (-5) — allocator overhead detection
• Client capacity >80% (-5) — connection exhaustion risk
• Replication lag >10MB (-10) — slave falling behind
• Slow queries max >500ms (-5)
• Fork duration >500ms (-5) — large dataset persistence delay
• Lazyfree pending >1000 (-3)
• Master IO >10s ago (-5) — link degradation

Recommendations Engine

Data-driven setup advice based on actual workload analysis:

• Memory: Optimal maxmemory based on current usage, policy recommendations
• Eviction: Detects policy misconfigurations (volatile-* with no TTL keys)
• Connections: maxclients sizing based on actual client load
• Persistence: RDB/AOF optimization, fork delay mitigation
• Performance: io-threads suggestion for high throughput, network tuning
• TTL Coverage: Warns about unbounded growth from missing TTLs
• Replication: HA recommendations for unprotected large datasets
• Slow Queries: Pattern analysis from SLOWLOG data

New UI Sections

• LATENCY & SLOW LOG: Percentile summary + slow query table
• RECOMMENDATIONS: Numbered actionable advice based on real metrics
• Enhanced HEALTH STATUS panel with 5 new indicators
• Enhanced MEMORY/PERSISTENCE/REPLICATION with new fields
