GET /storage/aggregates/{uuid}

Introduced In: 9.6

Retrieves the aggregate specified by the UUID. The recommend query cannot be used for this operation.

Expensive properties

There is an added computational cost to retrieving values for these properties. They are not included by default in GET results and must be explicitly requested using the fields query parameter. See Requesting specific fields to learn more.

Parameters

Name Type In Required Description

uuid

string

path

True

Aggregate UUID

show_spares

boolean

query

False

If set to 'true', the spares object is returned instead of records to show the spare groups in the cluster that are compatible with the aggregate. The default setting is 'false'.

  • Introduced in: 9.12

flash_pool_eligible

boolean

query

False

If set to 'true' along with show_spares, the spares object is restricted to return spare groups that are compatible with flash pool creation or addition for the specified aggregate. The default setting is 'false'.

  • Introduced in: 9.12

auto_provision_policy

query

False

If set to expand, a query is run on the system for the recommended optimal expansion layout of the aggregate.

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

Errors associated with the sample. For example, if the aggregation of data over multiple nodes fails, then any partial errors might return "ok" on success or "error" on an 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.

footprint

integer

A summation of volume footprints (including volume guarantees), in bytes. This includes all of the volume footprints in the block_storage tier and the cloud_storage tier. This is an advanced property; there is an added computational cost to retrieving its value. The field is not populated for either a collection GET or an instance GET unless it is explicitly requested using the fields query parameter containing either footprint or **.

snapshot

snapshot

iops_raw

The number of I/O operations observed at the storage object. This can 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 can be divided by the raw IOPS value to calculate the average latency per I/O operation.

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.

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

latency_raw

latency_raw

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

status

string

Errors associated with the sample. For example, if the aggregation of data over multiple nodes fails, then any partial errors might return "ok" on success or "error" on an 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_raw

throughput_raw

Throughput bytes observed at the storage object. This can be used along with delta time to calculate the rate of throughput bytes per unit of time.
