Once you’ve integrated with AWS CloudWatch, you have access to all metrics for the AWS Elastic Block Store service, which provides block level storage volumes for EC2 instances. EBS volumes behave like unformatted, unprocessed block devices.
To verify metrics are reporting, search for the metrics in the Metric details section of the Project Settings page.
The following table shows the Elastic Block Store metrics ingested by Lightstep.
|aws.ebs.volume_read_bytes||bytes||The total read bytes transferred during the period.|
|aws.ebs.volume_write_bytes||bytes||The total write bytes transferred during the period.|
|aws.ebs.volume_read_ops||count||The total volume read operations during the period.|
|aws.ebs.volume_write_ops||count||The total volume write operations during the period.|
|aws.ebs.volume_total_read_time||seconds||The total seconds for all read operations within the specified period.|
|aws.ebs.volume_total_write_time||seconds||The total seconds for all write operations within the specified period.|
|aws.ebs.volume_idle_time||seconds||The total seconds in which there were no active operations (read or write).|
|aws.ebs.volume_queue_length||count||The total read and write requests waiting to be complete in the specified period.|
|aws.ebs.volume_throughput_percentage||percent||The proportion of delivered IOPS to provisioned IOPS per second.|
|aws.ebs.volume_consumed_read_write_ops||count||The total number of read and write operations performed in a given amount of time (normalized to 256K capacity units).|
|aws.ebs.burst_balance||percent||The percentage used exclusively with volumes on General Purpose SSD (gp2), Throughput Optimized HDD (st1), and Cold HDD (sc1) drives.|
|aws.ebs.fast_snapshot_restore_credits_bucket_size||count||The maximum number of volume create credits that can be accumulated.|
|aws.ebs.fast_snapshot_restore_credits_balance||count||The number of volume create credits available.|
