class Aws::ComputeOptimizer::Types::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.

@!attribute [rw] 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 markdown="1"> 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][1].

   </note>

* `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.

@return [String]

@!attribute [rw] statistic

The statistic of the utilization metric.

The Compute Optimizer API, Command Line Interface (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][1] in the *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][2].
