Collected Statistics

MetricDescription
CPUUtilizationThe percentage of CPU utilization.
Units: Percentage
DatabaseConnections

The number of client network connections to the database instance.

The number of database sessions can be higher than the metric value because the metric value doesn't include the following:

  • Sessions that no longer have a network connection but which the database hasn't cleaned up
  • Sessions created by the database engine for its own purposes
  • Sessions created by the database engine's parallel execution capabilities
  • Sessions created by the database engine job scheduler
  • Amazon RDS connections

Units: Count

DiskQueueDepthThe number of outstanding I/Os (read/write requests) waiting to access the disk.
Units: Count
FreeableMemory

The amount of available random access memory.

For MariaDB, MySQL, Oracle, and PostgreSQL DB instances, this metric reports the value of the MemAvailable field of /proc/meminfo.

Units: Bytes

FreeStorageSpace

The amount of available local storage space. Applies to only Multi-AZ DB clusters.

(This doesn't apply to Aurora Serverless v2.)

Units: Bytes

NetworkReceiveThroughputThe incoming (receive) network traffic on the DB instance, including both customer database traffic and Amazon RDS traffic used for monitoring and replication.
Units: Bytes/Second
NetworkTransmitThroughputThe outgoing (transmit) network traffic on the DB instance, including both customer database traffic and Amazon RDS traffic used for monitoring and replication.
Units: Bytes/Second
ReadIOPSThe average number of disk read I/O operations per second.
Units: Count/Second
ReadLatencyThe average amount of time taken per disk I/O operation.
Units: Seconds
ReadThroughputThe average number of bytes read from disk per second.
Units: Bytes/Second
SwapUsageThe amount of swap space used on the DB instance. This metric is not available for SQL Server.
Units: Bytes
WriteIOPSThe average number of disk write I/O operations per second.
Units: Count/Second
WriteLatencyThe average amount of time taken per disk I/O operation.
Units: Seconds
