It includes real-time monitoring, metric collection, and analytics using Amazon CloudWatch, enabling you to set alarms and notifications for defined thresholds. It covers various categories such as performance, cache, and infrastructure metrics. Performance metrics include cache hit ratio, cache miss ratio, and latency, while cache metrics include evictions, and storage utilization. Infrastructure metrics include CPU utilization and memory usage. Using advanced monitoring, you can identify anomalies, optimize cache performance, and ensure that the cache functions at peak efficiency.
