View individual volume details
From the Volumes page, you can view more information for an individual volume.
-
Select Volumes > Active Volumes.
-
In the Actions column, select the
icon for the volume you want and select View Details.
After the page opens for the active volume, you can view recent volume data from the information bar.
| Heading | Description |
|---|---|
Account ID |
System-generated ID for the volume. |
Volume Size |
Total size of the volume. |
Used Capacity |
Shows how full the volume is. |
Average IOPS |
Average number of IOPS executed against the volume in the last 30 minutes. |
Average Throughput |
Average throughput executed against the volume in the last 30 minutes. |
Average Latency |
The average time, in microseconds, to complete read and write operations to the volume in the last 30 minutes. For more information, see this KB article. |
You can view additional details from the Show Volume Details drop-down menu. |
|
Access |
The read/write permissions assigned to the volume. |
Access Groups |
Associated volume access groups. |
Non-Zero Blocks |
Total number of 4KiB blocks with data after the last round of garbage collection operation has completed. |
Zero Blocks |
Total number of 4KiB blocks without data after the last round of garbage collection operation has completed. |
Snapshot Count |
The number of associated snapshots. |
Min IOPS |
The minimum number of IOPS guaranteed for the volume. |
Max IOPS |
The maximum number of IOPS allowed for the volume. |
Burst IOPS |
The maximum number of IOPS allowed over a short period of time. |
512e Enabled |
Identifies if 512e is enabled on a volume. |
QoS Throttle |
Represents the current throttling for the volume. The value does not include historical throttling on the volume. |
Primary Node ID |
Primary node for this volume. |
Secondary Node ID |
List of secondary nodes for this volume. Can be multiple values during transitory states, like change of secondary nodes, but will usually have a single value. |
Volumes Paired |
Indicates if a volume has been paired or not. |
Create Time |
The time the volume creation task was completed. |
Block Size |
Size of the blocks on the volume. |
IQN |
The iSCSI Qualified Name (IQN) of the volume. |
scsiEUIDeviceID |
Globally unique SCSI device identifier for the volume in EUI-64 based 16-byte format. |
scsiNAADeviceID |
Globally unique SCSI device identifier for the volume in NAA IEEE Registered Extended format. |
Attributes |
List of Name/Value pairs in JSON object format. |
View individual volume performance graphs
From the Volumes page, you can view performance activity for each volume in a graphical format. This information provides real-time statistics for throughput, IOPS, latency, queue depth, average IO size, and capacity for each volume.
-
Select Volumes > Volume Performance.
-
From the Volume drop-down list, select a Volume ID to view details for that volume. Note that the Volume drop-down list is searchable by Volume ID.
-
On the left, select a thumbnail graph to view performance graphs in detail. You can view the following graphs:
-
Throughput
-
IOPS
-
Latency
-
Queue Depth
-
Average IO Size
-
Capacity
You can also view the Average, Min, or Max for each graph too. Note that Average is the default view.
-
-
(Optional) You can export each graph as a CSV file by selecting the
icon. -
Alternatively, you can select Volumes > Active Volumes.
-
In the Actions column, select the
icon for the volume you want and select View Details.A separate page opens to display an adjustable timeline, which is synced with the performance graphs.
