AWS ebs metricset

Amazon Elastic Block Store (Amazon EBS) sends data points to CloudWatch for several metrics. Most EBS volumes automatically send five-minute metrics to CloudWatch only when the volume is attached to an instance. This aws ebs metricset collects these Cloudwatch metrics for monitoring purposes.

AWS Permissions

Some specific AWS permissions are required for IAM user to collect AWS EBS metrics.

ec2:DescribeRegions
cloudwatch:GetMetricData
cloudwatch:ListMetrics
tag:getResources
sts:GetCallerIdentity
iam:ListAccountAliases
