Host-Level Metrics - Amazon MemoryDB for Redis
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

Host-Level Metrics

The Amazon/MemoryDB namespace includes the following host-level metrics for individual nodes.

Metric Description Unit
CPUUtilization The percentage of CPU utilization for the entire host. Because Redis is single-threaded, and we recommend you monitor EngineCPUUtilization metric for nodes with 4 or more vCPUs. Percent
FreeableMemory The amount of free memory available on the host. This is derived from the RAM, buffers, and that the OS reports as freeable. Bytes
NetworkBytesIn The number of bytes the host has read from the network. Bytes
NetworkBytesOut The number of bytes sent out on all network interfaces by the instance. Bytes
NetworkPacketsIn The number of packets received on all network interfaces by the instance. This metric identifies the volume of incoming traffic in terms of the number of packets on a single instance. Count
NetworkPacketsOut The number of packets sent out on all network interfaces by the instance. This metric identifies the volume of outgoing traffic in terms of the number of packets on a single instance. Count
NetworkBandwidthInAllowanceExceeded The number of packets shaped because the inbound aggregate bandwidth exceeded the maximum for the instance. Count
NetworkConntrackAllowanceExceeded The number of packets shaped because connection tracking exceeded the maximum for the instance and new connections could not be established. This can result in packet loss for traffic to or from the instance. Count
NetworkLinkLocalAllowanceExceeded The number of packets shaped because the PPS of the traffic to local proxy services exceeded the maximum for the network interface. This impacts traffic to the DNS service, the Instance Metadata Service, and the Amazon Time Sync Service. Count
NetworkBandwidthOutAllowanceExceeded The number of packets shaped because the outbound aggregate bandwidth exceeded the maximum for the instance. Count
NetworkPacketsPerSecondAllowanceExceeded The number of packets shaped because the bidirectional packets per second exceeded the maximum for the instance. Count
SwapUsage The amount of swap used on the host. Bytes
