This could be caused by internal contention, blocked commands, slow clients, or downstream pressure from connected services.\n\n---\n\n## 📈 Impact\n\nIncreased command latency can lead to:\n\n- Slower application performance and timeouts\n- Delayed cache reads/writes\n- Poor user experience in latency-sensitive applications\n- Potential cascading effects on dependent systems\n\n---\n\n## 🛠️ Runbook\n\n### Initial Troubleshooting Steps\n\n1. **Identify the affected Redis node**.\n2. Go to [**Redis integration metrics**](https://app.datadoghq.com/monitors/manage?filter=redis) in Datadog.\n3. Review these metrics:\n   - `redis.net.latency_ms.p99`\n   - `redis.commands.per_sec`\n   - `redis.clients.blocked`\n   - Host-level CPU/memory/disk metrics\n4. Check for slow logs or blocked clients.\n5. Ensure no network congestion or saturation between Redis and calling services.\n\n---\n\n### Cause and Resolution\n\nCause | Resolution\n------|-----------\nCommand backlog or slow queries | Investigate slow logs and blocked clients.\nHigh memory or CPU pressure | Scale the node or optimize Redis configuration.\nNetwork degradation | Check latency and packet loss metrics.\nMisbehaving client | Identify traffic spike source or connection issues.\n\n---\n\n### 👥 Who should be notified?\n\nPlease route to the appropriate team: \n`@slack-yourteam-alerts`\n",
