Peformance metric for write I/O operations.

duration

string

The duration over which this sample is calculated. The time durations are represented in the ISO-8601 standard format. Samples can be calculated over the following durations:

iops

iops

The rate of I/O operations observed at the storage object.

latency

latency

The round trip latency in microseconds observed at the storage object.

status

string

Any errors associated with the sample. For example, if the aggregation of data over multiple nodes fails then any of the partial errors might be returned, "ok" on success, or "error" on any internal uncategorized failure. Whenever a sample collection is missed but done at a later time, it is back filled to the previous 15 second timestamp and tagged with "backfilled_data". "Inconsistent_ delta_time" is encountered when the time between two collections is not the same for all nodes. Therefore, the aggregated value might be over or under inflated. "Negative_delta" is returned when an expected monotonically increasing value has decreased in value. "Inconsistent_old_data" is returned when one or more nodes do not have the latest data.

throughput

throughput

The rate of throughput bytes per second observed at the storage object.

timestamp

string

The timestamp of the performance data.

iops_raw

The number of I/O operations observed at the storage object. This should be used along with delta time to calculate the rate of I/O operations per unit of time.

Name Type Description

other

integer

Performance metric for other I/O operations. Other I/O operations can be metadata operations, such as directory lookups and so on.

read

integer

Performance metric for read I/O operations.

total

integer

Performance metric aggregated over all types of I/O operations.

write

integer

Peformance metric for write I/O operations.

latency_raw

The raw latency in microseconds observed at the storage object. This should be divided by the raw IOPS value to calculate the average latency per I/O operation.

Name Type Description

timestamp

string

The timestamp of the performance data.

svm

Name Type Description

_links

_links

name

string

The name of the SVM.

uuid

string

The unique identifier of the SVM.

target

Name Type Description

alias

string

The iSCSI target alias of the iSCSI service.

The target alias can contain one (1) to 128 characters and feature any printable character except space (" "). A PATCH request with an empty alias ("") clears the alias.

Optional in POST and PATCH. In POST, this defaults to the name of the SVM.

name

string

The iSCSI target name of the iSCSI service. This is generated for the SVM during POST.

If required, the target name can be modified using the ONTAP command line.

  • example: iqn.1992-08.com.netapp:sn.574caf71890911e8a6b7005056b4ea79:vs.2

  • minLength: 1

  • readOnly: 1

  • Introduced in: 9.6

  • x-nullable: true

iscsi_service

An iSCSI service defines the properties of the iSCSI target for an SVM. There can be at most one iSCSI service for an SVM. An SVM's iSCSI service must be created before iSCSI initiators can log in to the SVM.

An iSCSI service is identified by the UUID of its SVM.

Name Type Description

_links

_links

enabled

boolean

The administrative state of the iSCSI service. The iSCSI service can be disabled to block all iSCSI connectivity to the SVM.

Optional in POST and PATCH. The default setting is true (enabled) in POST.
