ElastiCache adds CloudWatch diagnostics for node metrics
🔍 Amazon ElastiCache now publishes thirteen new Amazon CloudWatch metrics for node-based clusters to surface network throttling, memory fragmentation, and connection exhaustion without running INFO commands or manual baselining. The host- and engine-level diagnostics include network baseline percentages, allocator fragmentation, OS page-faults, connection rejects, pub/sub channel counts, and command throughput. Metrics are available in all commercial, China, and GovCloud regions at no additional cost and can be viewed in the ElastiCache monitoring tab or the AWS/ElastiCache namespace in CloudWatch.
