fabric

Properties of the fabric to which the FC port is attached.

Name Type Description

connected

boolean

Reports if the physical port has established a connection with the FC fabric.

connected_speed

integer

The negotiated data rate between the target FC port and the fabric in gigabits per second.

name

string

The name of the fabric to which the port is connected. This is only available when the FC port is connected to a fabric.

There is an added cost to retrieving this property's value. It is not populated for either a collection GET or an instance GET unless it is explicitly requested using the fields query parameter. See Requesting specific fields to learn more.

port_address

string

The FC port address of the host bus adapter (HBA) physical port.

Each FC port in an FC switched fabric has its own unique FC port address for routing purposes. The FC port address is assigned by a switch in the fabric when that port logs in to the fabric. This property refers to the FC port address given to the physical host bus adapter (HBA) port when the port performs a fabric login (FLOGI).

This is useful for obtaining statistics and diagnostic information from FC switches.

This is a six-digit hexadecimal encoded numeric value.

switch_port

string

The switch port to which the FC port is connected.

iops

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

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.
