Calculating IOPS Utilization for EBS Volumes
When looking at an EBS volume in CloudWisdom, you’ll notice that in addition to the metrics we collect from AWS, we also create a number of computed metrics, one of which is netuitive.aws.ebs.iopsutilization. Simply put, IOPS Utilization compares the current number of IOPS that the disk is performing against the total IOPS capacity, and expresses this as a percentage. Thus, if you are currently running 1050 IOPS against a volume whose capacity is 3000 IOPS, the IOPS Utilization would be 35%.
