It is designed for the low-latency caching, session storage, and real-time data needs of modern applications, including AI workloads that depend on fast vector and embedding lookups. Because user-facing applications often query Redis directly, even small regressions in latency, hit rate, or memory pressure can degrade the user experience. Datadog’s [Azure Managed Redis integration](https://app.datadoghq.com/integrations?search=azure%20managed%20redis&integrationId=azure-managed-redis) gives teams full visibility into the activity, utilization, and performance of their cache instances, with no agent to install. Once the integration is configured, Managed Redis metrics flow into Datadog automatically and populate out-of-the-box (OOTB) dashboards and monitors. In this post, we’ll explore how to: - [Monitor Azure Managed Redis metrics](#monitor-azure-managed-redis-metrics) - [Catch performance regressions before they affect users](#catch-performance-regressions-before-they-affect-users) - [Optimize Azure Managed Redis cache efficiency and capacity](#optimize-azure-managed-redis-cache-efficiency-and-capacity) ## Monitor Azure Managed Redis metrics After you enable the integration, Datadog begins collecting [more than 20 metrics](https://docs.datadoghq.com/integrations/azure-managed-redis.md#data-collected) across every Managed Redis cache in your Azure environment. The OOTB [Azure Managed Redis Overview dashboard](https://app.datadoghq.com/dash/integration/32325/azure-managed-redis-overview) organizes the metrics into views that help you understand workload activity, cache efficiency, resource pressure, latency, and availability across your Redis deployments. ![Datadog dashboard showing total keys, hit rate, miss rate, and latency metrics for an Azure Managed Redis instance.](https://web-assets.dd-static.net/42588/1779904437-azure-managed-redis-overview-dashboard.png) Workload metrics such as `operations_per_second` and `connectedclients` help teams understand traffic patterns and connection volume, while cache efficiency metrics like `cachehits` and `cachemisses` provide visibility into how effectively the cache is serving requests. Resource and performance metrics such as `usedmemorypercentage`, `server_load`, and `cache_latency` help identify memory pressure, saturation, and emerging latency issues before they affect applications. ![The Data Collected tab on the Azure Managed Redis integration tile, listing metrics for cache performance and utilization.](https://web-assets.dd-static.net/42588/1779904497-azure-managed-redis-data-collected.png) ## Catch performance regressions before they affect users Many Redis problems show up as latency before they show up as errors. The Azure Managed Redis Overview dashboard pairs `cache_latency` with `server_load` and `percent_processor_time` so that you can tell whether a slowdown is driven by the cache or by upstream traffic. For example, consider an API team that notices p99 latency increasing on a checkout endpoint. The dashboard shows `server_load` sustained above 80% on the cache that backs the session store, while `operations_per_second` and `connectedclients` have both spiked after a marketing push. The team scales up the cache, and the latency decreases within minutes. To move from reactive troubleshooting to proactive alerting, you can use the integration’s recommended “Azure Managed Redis server load is high” monitor. When `server_load` crosses your threshold, the alert fires with the cache name and region pre-populated, so responders can quickly investigate the issue. ## Optimize Azure Managed Redis cache efficiency and capacity A healthy Redis deployment depends as much on what’s in the cache as how fast the cache responds. The dashboard surfaces hit rate, miss rate, evictions, and used memory percentage together so that you can spot the patterns that quietly degrade performance: - Falling hit rate with steady traffic suggests that time-to-live (TTL) values are too aggressive or that the working set has outgrown the instance. - Rising `evictedkeys` alongside `usedmemorypercentage` near 100% means that the cache is under memory pressure and starting to drop frequently accessed keys. - Climbing `totalkeys` with flat `cachehits` points to keys being written but never read, a common sign of stale serialization paths or orphaned application code. The recommended “Azure Managed Redis cache hit rate is low” monitor watches the hit-to-miss ratio and alerts you when efficiency drops below your target, giving you a leading indicator of latency problems before users feel them. ## Get started monitoring Azure Managed Redis The Azure Managed Redis integration is one of Datadog’s many Azure integrations, including [Azure SQL Managed Instance](https://docs.datadoghq.com/integrations/azure-sql-managed-instance.md), [Azure Service Bus](https://docs.datadoghq.com/integrations/azure-service-bus.md), and [Azure OpenAI](https://docs.datadoghq.com/integrations/azure-openai.md). It helps you monitor and optimize cache efficiency and identify performance issues before they affect users.
