Glossary of Cloudability Dimensions and Metrics - Utilization

Cloudability's reporting tools allow you to slice and dice your utilization data so you can figure out exactly how your infrastructure is being used. Divided into two sections, the dimensions and metrics that are available in your reports are identified below.

  1. Utilization Dimensions
  2. Utilization Metrics

Utilization Dimensions

Account ID: The 12-digit AWS number used to identify an account. For cost analytics of consolidated billing accounts, this refers to a linked account.

Account Name: The name associated with an AWS account. For cost analytics of consolidated billing accounts, this refers to a linked account.

AMI: This dimension filters the data you request for all instances running this EC2 Amazon Machine Image (AMI). Available for instances with Detailed Monitoring enabled.

Architecture: The base architecture of the instance hardware. (e.g. x86, x86_64, i386)

Availability Zone: A combination of the region and zone in which an instance exists or a usage charge occurred (e.g. us-east-1a).

CPU Clock Speed: The base clock speed of the processors on the instance. (GHz)

Current State: The current state of the EC2 instance (e.g. running, stopped). See the AWS Instance Lifecycle User Guide for additional information.

Date: The calendar date (e.g. YYYY-MM-DD).

Day: The day of the month.

Day of Week: The weekday (e.g. Monday).

Days Alive: The total number of days since the instance was initially launched.

DNS Name: The public DNS name associated with a particular EC2 instance (e.g. ec2-54-205-210-122.compute-1.amazonaws.com).

Hour: The numeric hour of the day (e.g. 1pm => 13).

Instance Category: The instance category. (e.g. General Purpose, Compute Optimized, etc.)

Instance ID: The ID associated with a particular AWS instance.

Instance Name: The name of a particular EC2 instance.

Instance Type: The size of an instance (e.g. m1.medium). Click here for more information. 

IP Address: The IP address associated with a particular EC2 instance.

Launch Date: The launch date of a particular instance (e.g. 2014-01-22).

Launch Day: The launch day of a particular instance (e.g. Monday).

Launch Day of Week: The day of the week that a particular instance was launched (e.g. Monday).

Launch Month: The numeric month in which an instance was launched (e.g. 1 => January).

Launch Time: The date/time value describing when an instance was launched (e.g. 2000-01-01T22:46:34Z).

Launch Week: The week of the year in which an instance was launched (i.e. 52 would indicate the last week in a calendar year).

Launch Year: The year in which an instance was launched.

Month: The numeric calendar month (e.g. 2014-1-15 => 12).

OS: The operating system of an instance (e.g. linux).

Private DNS Name: Amazon EC2 instances need IP addresses to communicate. Public IP addresses enable communication over the internet.

Private IP: Amazon EC2 instances need IP addresses to communicate. Private IP addresses enable communication.

Processor Architecture: The CPU architecture.

Region: Region in which an instance exists or a usage charge occurred (e.g. US East).

Security Group IDs: A security group acts as a firewall that controls the traffic for one or more instances. Each security group is identified by a unique ID (e.g. sg-xxxxxxxx).

Security Groups Names: A security group acts as a firewall that controls the traffic for one or more instances. Each security group requires a unique name (limit 255 characters).

Storage Type

Subnet ID: The subnet ID associated with an EC2 instance. If there is a subnet ID listed, the instance is in a VPC.

Virtualization: The virtualized environment-if any-running on a given instance.

Week: The numeric calendar week.

Year: The calendar year (e.g. 2014).

Zone: Availability Zone in which an instance exists or a usage charge occurred (e.g. 1a).


Utilization Metrics

Avg CPU Utilization: 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 upon a selected instance.

Avg Estimated Cost: The average estimated cost of an instance based on the selected timeframe (utilization hours * avg estimated hourly instance cost).

Avg Hourly Cost: The average hourly cost based on the base rates established by AWS.

Avg Hourly Cost Per Instance: The average hourly cost per instance based on the base rates established by AWS.

Avg Running Instances Per Hour: The average number of running instances per hour. Click here for additional information. 

Bandwidth In: The 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.

Bandwidth Out: The 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.

Cost (Estimated On-demand): The estimated cost based on the values found in the AWS Cost Allocation File.

Disk AccessTotal bytes read and written for all ephemeral disks available to the instance (if your instance uses Amazon EBS, see Amazon EBS Metrics).

Disk I/O: Completed read and write operations from all ephemeral disks available to the instance.

Disk Read Access: Total bytes read from all ephemeral disks available to the instance.

Disk Read I/O: Completed read operations from all ephemeral disks available to the instance.

Disk Write Access: Total bytes written to all ephemeral disks available to the instance.

Disk Write I/O: Completed write operations to all ephemeral disks available to the instance.

Hours Since Launch: The number of hours elapsed since an instance initially launched.

Launched Instances: The total number of launched instances in a given time period.

Memory: The amount of memory available to the instance.

Storage: The amount for storage available to the instance. This number will not include EBS.

Storage Devices: The total number of storage devices associated with an instance in a give time period.

Total Bandwidth: Total bytes transferred by a particular instance.

Unique Instance Count: The total number of unique instances in a running state during a given time period.

Utilization Hours: The total number of usage hours on an instance in a particular timeframe.

Utilization Rate: The utilization rate of an instance represents utilization as a percentage of the particular time period. For example, an instance running for 12 hours in a 24 hour period has a utilization rate of 50%.
