Cloudability Glossary of utilization dimensions and metrics

Edit online

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

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: average 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. For more information, see Frequently used dimensions and metrics .
  • 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 instance. This metric identifies the volume of outgoing network traffic to an application on a single instance.
  • Burst Balance : Provides information about the percentage of I/O credits (for gp2) or throughput credits (for st1 and sc1) remaining in the burst bucket. Used with General Purpose SSD (gp2), Throughput Optimized HDD (st1), and Cold HDD (sc1) volumes only.
  • Cost (Estimated On-demand) : The estimated cost based on the values found in the AWS Cost Allocation File.
  • CPU Total (blue line) : The normalized percentage of maximum CPU utilization in the indicated hour, based on the maximum instance count for the entire ASG in the time window of 10 or 30 days. Example: If there are five instances in an ASG and all 5 instances are utilizing 100% of their CPU then the CPU total is 100%. If one instance is utilizing 100% of its CPU and the other four instances are utilizing 0% of their CPUs then the CPU total is 20%.

  • CPU Utilization (Max) : The maximum percentage of CPU Utilization reached for the hour. For EC2, this is the maximum percentage of allocated EC2 compute units in use for an instance. When aggregated, this reports the peak across all instances and across the entire time period.

  • Disk Access : Total 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.

Example: If there are five instances in an ASG and all five instances are utilizing 100% of their memory, then the Memory total is 100%. If one instance is utilizing 100% of its memory and the other four instances are utilizing 0% of their memory then the Memory total is 20%.
