Amazon ElastiCache customers can now detect network throttling, memory fragmentation, and connection exhaustion, using thirteen new Amazon CloudWatch metrics for node-based clusters. You can monitor these host-level and engine-level diagnostics directly from CloudWatch without running INFO commands on individual nodes or calculating baselines from raw byte counters. Network capacity: NetworkBaselineUsageInPercentage, NetworkBaselineUsageOutPercentage, NetworkBaselineMaxUsageInPercentage, and NetworkBaselineMaxUsageOutPercentage report network utilization relative to instance baseline, enabling portable alarms that remain valid across instance type changes. Values above 100 percent signal that a host is consuming burst credits, a leading indicator that a sustained workload will eventually lead to credit exhaustion and throttling. The variants capturing max report per-second bursts that averaged metrics can hide. Memory health: UsedMemoryDataset shows memory consumed by actual stored data excluding engine overhead. AllocatorFragmentationBytes and AllocatorFragmentationRatio isolate fragmentation that the activedefrag parameter can address. MajorPageFaults captures OS-level page faults that indicate memory pressure beyond what the engine can surface. Connectivity health: BlockedConnections and RejectedConnections surface connections waiting on blocking commands and connections turned away when the maxclients limit is reached. When RejectedConnections is non-zero, raise maxclients or diagnose client-side connection pool leaks. Pub/sub workloads: PubSubChannels and PubSubShardChannels expose active classic and sharded channels on each node. When classic channel counts are growing with utilization, consider switching to sharded pub/sub to scale horizontally. Command throughput: ProcessedCommands provides total command throughput across all command types. These metrics are available for node-based clusters in all commercial AWS Regions and the AWS China and AWS GovCloud (U
