GET /network/ethernet/ports/{uuid}/metrics

Introduced In: 9.8

Retrieves historical performance metrics for a port.

Parameters

Name Type In Required Description

timestamp

string

query

False

Filter by timestamp

duration

string

query

False

Filter by duration

throughput.read

integer

query

False

Filter by throughput.read

throughput.total

integer

query

False

Filter by throughput.total

throughput.write

integer

query

False

Filter by throughput.write

status

string

query

False

Filter by status

uuid

string

path

True

Unique identifier of the port.

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

throughput

The rate of throughput bytes per second observed at the interface.

Name Type Description

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.

records

Throughput performance for the Ethernet port.

Name Type Description

_links

_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:

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

throughput

The rate of throughput bytes per second observed at the interface.

timestamp

string

Port UUID
