aws ebs metricset

edit

aws ebs metricset

edit

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

edit

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

Dashboard

edit

The aws ebs metricset comes with a predefined dashboard. For example:

Configuration example

edit

- module: aws
  period: 300s
  metricsets:
    - ebs
  # This module uses the aws cloudwatch metricset, all
  # the options for this metricset are also available here.

Metrics

edit

Please see more details for each metric in ebs-cloudwatch-metric.

Metric Name	Statistic Method
VolumeReadBytes	Average
VolumeWriteBytes	Average
VolumeReadOps	Average
VolumeWriteOps	Average
VolumeQueueLength	Average
VolumeThroughputPercentage	Average
VolumeConsumedReadWriteOps	Average
BurstBalance	Average
VolumeTotalReadTime	Sum
VolumeTotalWriteTime	Sum
VolumeIdleTime	Sum

This is a default metricset. If the host module is unconfigured, this metricset is enabled by default.
