svm.uuid

string

path

True

The unique identifier of the SVM.

interval

string

query

False

The time range for the data. Examples can be 1h, 1d, 1m, 1w, 1y. The period for each time range is as follows:

  • 1h: Metrics over the most recent hour sampled over 15 seconds.

  • 1d: Metrics over the most recent day sampled over 5 minutes.

  • 1w: Metrics over the most recent week sampled over 30 minutes.

  • 1m: Metrics over the most recent month sampled over 2 hours.

  • 1y: Metrics over the most recent year sampled over a day.

  • Default value: 1

  • enum: ["1h", "1d", "1w", "1m", "1y"]

return_timeout

integer

query

False

The number of seconds to allow the call to execute before returning. When iterating over a collection, the default is 15 seconds. ONTAP returns earlier if either max records or the end of the collection is reached.

  • Default value: 1

  • Max value: 120

  • Min value: 0

fields

array[string]

query

False

Specify the fields to return.

max_records

integer

query

False

Limit the number of records returned.

order_by

array[string]

query

False

Order results by specified fields and optional [asc

desc] direction. Default direction is 'asc' for ascending.

return_records

boolean

query

False

iops

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

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

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

records

Performance numbers, such as IOPS latency and throughput, for SVM protocols.

Name Type Description

_links

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.
