UtilizationMetric

Describes a utilization metric of a resource, such as an Amazon EC2 instance.

Compare the utilization metric data of your resource against its projected utilization metric data to determine the performance difference between your current resource and the recommended option.

Contents

name

The name of the utilization metric.

The following utilization metrics are available:

  • Cpu - The percentage of allocated EC2 compute units that are currently in use on the instance. This metric identifies the processing power required to run an application on the instance.

    Depending on the instance type, tools in your operating system can show a lower percentage than CloudWatch when the instance is not allocated a full processor core.

    Units: Percent

  • Memory - The percentage of memory that is currently in use on the instance. This metric identifies the amount of memory required to run an application on the instance.

    Units: Percent

    Note

    The Memory metric is returned only for resources that have the unified CloudWatch agent installed on them. For more information, see Enabling Memory Utilization with the CloudWatch Agent.

  • GPU - The percentage of allocated GPUs that currently run on the instance.

  • GPU_MEMORY - The percentage of total GPU memory that currently runs on the instance.

    Note

    The GPU and GPU_MEMORY metrics are only returned for resources with the unified CloudWatch Agent installed on them. For more information, see Enabling NVIDIA GPU utilization with the CloudWatch Agent.

  • EBS_READ_OPS_PER_SECOND - The completed read operations from all EBS volumes attached to the instance in a specified period of time.

    Unit: Count

  • EBS_WRITE_OPS_PER_SECOND - The completed write operations to all EBS volumes attached to the instance in a specified period of time.

    Unit: Count

  • EBS_READ_BYTES_PER_SECOND - The bytes read from all EBS volumes attached to the instance in a specified period of time.

    Unit: Bytes

  • EBS_WRITE_BYTES_PER_SECOND - The bytes written to all EBS volumes attached to the instance in a specified period of time.

    Unit: Bytes

  • DISK_READ_OPS_PER_SECOND - The completed read operations from all instance store volumes available to the instance in a specified period of time.

    If there are no instance store volumes, either the value is 0 or the metric is not reported.

  • DISK_WRITE_OPS_PER_SECOND - The completed write operations from all instance store volumes available to the instance in a specified period of time.

    If there are no instance store volumes, either the value is 0 or the metric is not reported.

  • DISK_READ_BYTES_PER_SECOND - The bytes read from all instance store volumes available to the instance. This metric is used to determine the volume of the data the application reads from the disk of the instance. This can be used to determine the speed of the application.

    If there are no instance store volumes, either the value is 0 or the metric is not reported.

  • DISK_WRITE_BYTES_PER_SECOND - The bytes written to all instance store volumes available to the instance. This metric is used to determine the volume of the data the application writes onto the disk of the instance. This can be used to determine the speed of the application.

    If there are no instance store volumes, either the value is 0 or the metric is not reported.

  • NETWORK_IN_BYTES_PER_SECOND - The number of bytes received by the instance on all network interfaces. This metric identifies the volume of incoming network traffic to a single instance.

  • NETWORK_OUT_BYTES_PER_SECOND - The number of bytes sent out by the instance on all network interfaces. This metric identifies the volume of outgoing network traffic from a single instance.

  • NETWORK_PACKETS_IN_PER_SECOND - The number of packets received by the instance on all network interfaces. This metric identifies the volume of incoming traffic in terms of the number of packets on a single instance.

  • NETWORK_PACKETS_OUT_PER_SECOND - The number of packets sent out by the instance on all network interfaces. This metric identifies the volume of outgoing traffic in terms of the number of packets on a single instance.

Type: String

Valid Values: Cpu | Memory | EBS_READ_OPS_PER_SECOND | EBS_WRITE_OPS_PER_SECOND | EBS_READ_BYTES_PER_SECOND | EBS_WRITE_BYTES_PER_SECOND | DISK_READ_OPS_PER_SECOND | DISK_WRITE_OPS_PER_SECOND | DISK_READ_BYTES_PER_SECOND | DISK_WRITE_BYTES_PER_SECOND | NETWORK_IN_BYTES_PER_SECOND | NETWORK_OUT_BYTES_PER_SECOND | NETWORK_PACKETS_IN_PER_SECOND | NETWORK_PACKETS_OUT_PER_SECOND | GPU_PERCENTAGE | GPU_MEMORY_PERCENTAGE

Required: No

statistic

The statistic of the utilization metric.

The Compute Optimizer API, AWS Command Line Interface (AWS CLI), and SDKs return utilization metrics using only the Maximum statistic, which is the highest value observed during the specified period.

The Compute Optimizer console displays graphs for some utilization metrics using the Average statistic, which is the value of Sum / SampleCount during the specified period. For more information, see Viewing resource recommendations in the AWS Compute Optimizer User Guide. You can also get averaged utilization metric data for your resources using Amazon CloudWatch. For more information, see the Amazon CloudWatch User Guide.

Type: String

Valid Values: Maximum | Average

Required: No

value

Type: Double
