Host-Level Metrics - Amazon MemoryDB

The AWS/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 Valkey and Redis OSS are single-threaded, 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 number is derived from the memory in RAM and buffers 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
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
NetworkMaxBytesIn The maximum per second burst of received bytes within each minute. Bytes
NetworkMaxBytesOut The maximum per second burst of transmitted bytes within each minute. Bytes
NetworkMaxPacketsIn The maximum per second burst of received packets within each minute. Count
NetworkMaxPacketsOut The maximum per second burst of transmitted packets within each minute. Count
SwapUsage The amount of swap used on the host. Bytes
