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.

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 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
