get /v9/storage/nodes/{nodeId}/statistics/io-profile

Get IO profile statistics from a specific cluster node, covering the recent past (up to an hour), of client access. The results are grouped by virtual server, filesystem, virtual volume and client address.

This API call does not work on all platforms and can potentially return a large amount of data.

Note: The objects returned by this API call may be pre-filtered based on the virtual server access granted by the API key used for authentication.

Authentication: x_subsystem_user Api Key "X-Subsystem-User"

Authentication: x_subsystem_password Api Key "X-Subsystem-Password"

Authentication: api_key Api Key "X-Api-Key"

Authentication: basicAuth HTTP - basic scheme

Path parameters

nodeId required

Either a node object ID or a cluster node ID

Query parameters

durationInSeconds Integer

Duration of the time window that the statistics are retrieved for. The duration is limited to the maximum history buffer which is one hour

int32

Example: 60

Default: 10

subsampleFactor Integer

Cuts down the number of historic samples processed to generate the statistics. If there is a lot of traffic on the system and the statistics take a significant time to return, then increase this value

int32

Example: 1

Default: 0
