AWS cloud metric reference

Table of contents
No headers

The following table details the AWS metrics available for instances using cloud monitoring.

These terms are included in the table:

  • Amazon Machine Image (AMI) provides information required to launch an instance.
  • Amazon Resource Name (ARN) is a format to identify resources in AWS.
  • Key Management Service (KMS) is a managed service to create and control data encryption keys.
MetricDescription
InstanceAWS EC2 instance
Instance NameUser-friendly name for the AWS EC2 instance.
RegionThe region where an instance is located. Regions are divided into Availability Zones to protect instances from failures in other Availability Zones.
Auto-Scaling GroupThe group an instance belongs to that is used to calculate the number of Amazon EC2 instances available to handle the load for an application.
StatusCalculated value of Up/ Down.
StateInstance state reported by AWS: Up/Down.
Platform The OS platform, such as Windows. This is not returned for all platform types.
ArchitectureCPU architecture type. Currently AWS supports two CPU architecture types, "i386" and "x86_64".
Public DNS Name

The public hostname of the instance that resolves to the instance's public or Elastic IP address.

Example: ec2-54-213-116-42.us-west-2.compute.amazonaws.com

Private DNS Name

The internal hostname of the instance that resolves to the instance's private IP address.

Example: fogbugz.dev.local

Subnet ID

The range of IP addresses in a virtual private cloud (VPC) that the instance was launched into, if applicable. Click here to learn more about VPCs and subnets.

Source/Destination Check

Indicates if source/destination checks are being performed on an instance to determine if it sends/receives traffic.

Instance IDThe ID for the cloud instance.
Instance Type

The type of instance determines your instance’s CPU capacity, memory, and storage (for example, m1.small or c1.xlarge). See the AWS Instance Types page for full details.

Instance Creation DateThe time the instance launched.
Image ID

An encrypted machine image stored in Amazon Elastic Block Store or Amazon Simple Storage Service. An Amazon Machine Image (AMI) acts as a template of a computer's root drive. It contains the OS and can also include software and layers of your application such as database servers, middleware, and web servers.

Example: ami-3231adad

AMI Launch Index

A number indicating the order in which the instance was launched. The first or only instance has an index of 0.

Last Poll The time when the instance was last polled by Orion Platform.
Next PollThe time when the instance will be polled again by Orion Platform.
Monitored

The level of CloudWatch monitoring that is enabled for this instance: Basic/Detailed

RAM disk ID

The RAM disk associated with the image, if one was specified.

Example: ari-7d0d2509

Kernel IDThe OS kernel associated with the AMI.
Root Device typeThe root device type used by the AMI. The AMI can use an Amazon EBS or instance store root device.
Root Device NameThe ID of the system device contains the boot volume.
EBS optimizedIndicates if additional, dedicated throughput between Amazon EC2 and Amazon EBS was enabled for the instance.
TenancyType of tenancy: Dedicated/Default. If dedicated, the instance is running on single-tenant, dedicated hardware.
IAM role

The IAM roles (for example: s3acces) associated with the instance, if applicable.

OwnerThe AWS account number of the AMI owner, without dashes.
Security GroupsThe security groups to which the instance belongs. A security group is a collection of firewall rules that restrict the network traffic for the instance.
VPC ID

The ID of the virtual private cloud (VPC) the instance was launched into, if applicable. A VPC is an isolated portion of the AWS cloud.

For example: vpc-c46c9ea1

KeyPair nameThe name of the key pair, if this instance was launched with an associated KeyPair.
Placement GroupIf the cloud instance is a cluster instance, this is the cluster group to which the instance belongs.
VirtualizationThe type of virtual machine running: paravirtual/hvm.
ReservationThe reservation ID used to launch the instance.
State Transition ReasonThe reason for the change of instance state. For example, if the instance was terminated, the reason might be ‘User initiated shutdown’.
Public IP addressPublic Internet routable IP address of the instance
Private IP addressThe private IP address of the instance. Multiple IP addresses are listed if there is more than one network interface to the instance.
Secondary Private IP addressAny secondary private IP addresses assigned to a network interface attached to the instance.
Elastic IP addressThe Elastic IP address assigned to the instance, if applicable. Elastic IP addresses are static IP addresses assigned to your account that you can quickly remap to other instances.
CPU utilizationThe 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 upon a selected instance.
Disk Read OpsCompleted write operations to all ephemeral disks available to the instance in a specified period of time. This metrics requires EBA volumes.
Disk WriterOpsCompleted write operations from all ephemeral disks available to the instance. This metrics requires EBA volumes.
DiskReadBytesBytes read from all ephemeral disks available to the instance. This metrics requires EBA volumes.
DiskWriteBytesBytes written to all ephemeral disks available to the instance. This metrics requires EBA volumes.
NetworkInThe number of bytes received on all network interfaces by the instance. This metric identifies the volume of incoming network traffic to an application on a single instance.
NetworkOutThe number of bytes sent out on all network interfaces by the instance. This metric identifies the volume of outgoing network traffic to an application on a single instance.

The following table details the AWS metrics available for monitored volumes.

MetricDescription
Volume IDUser-friendly name of the cloud volume
Volume TypeIndicates whether the volume is a standard (Magnetic), gp2 (General Purpose (SSD)) or io1 (Provisioned IOPS (SSD))
SizeThe capacity of the Amazon EBS volume in GiB. Note that 1 GiB = 1024^3 bytes, whereas 1 GB = 1000^3 bytes.
Alarm StatusCloudWatch alarm summary for alarms monitoring metrics for this volume.
StateThe current state of the volume. For example: Creating/Available/In-Use/Deleting/Error
EncryptedIndicates whether the volume is encrypted. For example: Encrypted/Not Encrypted
RegionThe Availability Zone where the volume is located
CreatedTimeDate/time the Amazon EBS volume was created
AttachedTimeDate/Time the Amazon EBS volume was attached to the Instance
Delete on TerminationDenotes if the volume will be deleted when the associated instance it is attached to is terminated: True/False
KMS Key IDA unique identifier for the customer master key. This value can be a globally unique ID.
KMS Key AliasesKey Management Service friendly name
KMS Key ARNThe Amazon Resource Name for the Key Management Service key
Product CodesDevPay or AWS Marketplace codes associated with the volume, if applicable
SnapshotThe ID of the snapshot used to create the volume, if applicable. A snapshot is a copy of an Amazon EBS volume at a point in time.
Volume Idle TimeThe total number of seconds in a specified period of time when no read or write operations were submitted.
Throughput Percentage

Only used with Provisioned IOPS volumes. The percentage of I/O operations per second (IOPS) delivered of the total IOPS provisioned for an Amazon EBS volume. Provisioned IOPS (SSD) volumes deliver within 10 percent of the provisioned IOPS performance 99.9 percent of the time over a given year.

Read Bandwidth (KB/S)Sum(VolumeReadBytes) / Period / 1024
Write Bandwidth (KB/S)Sum(VolumeWriteBytes) / Period / 1024
Read Throughput IOPSSum(VolumeReadOps) / Period
Write Throughput IOPSSum(VolumeWriteOps) / Period
Average Queue LengthThe number of read and write operation requests waiting to be completed in a specified period of time.
Average Read Size The total number of bytes read in a specified period of time.
Average Write SizeThe total number of bytes written in a specified period of time.
Average Read LatencyThe total number of seconds spent by all operations that completed in a specified period of time. If multiple requests are submitted at the same time, this total could be greater than the length of the period. For example, for a period of 5 minutes (300 seconds): if 700 operations completed during that period, and each operation took 1 second, the value would be 700 seconds.
Average Write LatencyThe total number of seconds spent by all operations that completed in a specified period of time. If multiple requests are submitted at the same time, this total could be greater than the length of the period. For example, for a period of 5 minutes (300 seconds): if 700 operations completed during that period, and each operation took 1 second, the value would be 700 seconds.
Consumed R/W IOPSUsed with Provisioned IOPS (SSD) volumes only. The total amount of read and write operations (normalized to 256K capacity units) consumed in a specified period of time. I/O operations that are smaller than 256K each count as 1 consumed IOPS. I/O operations that are larger than 256K are counted in 256K capacity units. For example, a 1024K I/O would count as 4 consumed IOPS.
