Detail View

To display the detail view for an Amazon EBS disk:

Navigate to the Observe page.
Under Database & Storage, click Storage.
The Storage list view now displays.
Click the AWS tab to display only AWS storage entities.
From the list, click a Disk ID to display the detail view.
The detail view displays metrics, key performance indicators, and properties (attributes) related to the instance you selected.

Metrics and Key Performance Indicators

Cisco Cloud Observability displays the following metrics and key performance indicators (KPIs) for Amazon EBS. See Amazon CloudWatch metrics for Amazon EBS.

Display Name	Source Metric	Description
Volume Queue Length (Count)	`VolumeQueueLength`	The number of read and write operation requests waiting to be completed in a specified period of time.
Time Spent Idle (Sec)	`VolumeIdleTime`	The total number of seconds in a specified period of time when no read or write operations were submitted. This metric is not supported with Multi-Attach enabled disks.
Throughput Percentage	`VolumeThroughputPercentage`	Used with Provisioned IOPS SSD disks only. The percentage of I/O operations per second (IOPS) delivered of the total IOPS provisioned for an Amazon EBS disk. This metric is not supported with Multi-Attach enabled disks.
IOPS (Ops/Sec)	`VolumeReadOps` `VolumeWriteOps`	The number of read IOs performed on a disk. The number of write IOs performed on a disk.
Throughput (Bytes/Sec)	`VolumeReadBytes` `VolumeWriteBytes`	The bytes/sec read from a disk. The bytes/sec written to a disk.
Total Read/Write Time (Sec)	`VolumeTotalReadTime` `VolumeTotalWriteTime`	The total number of seconds spent by all read operations that completed in a specified period of time. This metric is not supported with Multi-Attach enabled disks. The total number of seconds spent by all write operations that completed in a specified period of time. This metric is not supported with Multi-Attach enabled disks.
Consumed Read Write Operations (Count)	`VolumeConsumedReadWriteOps`	Used with Provisioned IOPS SSD disks only. The total amount of read and write operations (normalized to 256K capacity units) consumed in a specified period of time.

Cloud Provider	`cloud.provider`	The name of the cloud provider of the disk.
Account ID	`cloud.account.id`	The cloud account ID where the resource is assigned.
Location	`cloud.region`	The geographical region where the resource is running.
Zones	`cloud.availability_zone`	The logical zone list for the disk.
Created At	`CreateTime`	The timestamp when the attachment was created.
IOPS	`IOPS`	The input/output operations per second; measured KiB; the maximum amount of data that a disk type counts as a single I/OSSD max: 256 KiBHDD max: 1,024 KiB.
Size	`Size`	The disk size in GiB.
State	`Attachments_State`	The disk attachment state.
Disk ID	`VolumeID`	The unique disk identifier.
Type	`VolumeType`	The EBS disk type (gp2, gp3, io1, io2, st1, sc1, standard).

Retention and Purge Time-To-Live (TTL)

For all cloud and infrastructure entities, the retention TTL is 180 minutes (3 hours) and the purge TTL is 525,600 minutes (365 days).
