<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: NetApp Physical Disk v2 Sensor

The NetApp Physical Disk v2 sensor monitors physical disks of a NetApp storage system via the Representational State Transfer (REST) application programming interface (API) using ONTAP as of version 9.9.

i_round_redThis sensor was converted to a new framework so that it will continue to function after the changes of the ONTAP REST API.

Consider the following remarks and requirements for this sensor:



Credentials for NetApp

  • This sensor requires an ONTAP System Manager user account with the role readonly and with access to the HTTP application with Password authentication.

Permissions for the ONTAP REST API

  • This sensor requires permissions for the ONTAP REST API.
  • This sensor requires the role readonly with the following permissions for the ONTAP REST API:

Access level Read-Only:

    • /api
    • /api/security/audit/destinations

Access level Read/Write:

    • /api/security/authentication/password

Access level None:

    • /api/security


  • This sensor requires credentials for NetApp.


  • This sensor requires ONTAP 9.10 for some channels.

NetApp versions

  • This sensor supports ONTAP as of version 9.9. If you want to use NetApp cDOT as of version 8.3 or ONTAP from version 9.0 to version 9.8, use the NetApp Physical Disk sensor.


  • This sensor supports IPv6.

Performance impact

  • This sensor has a very low performance impact.


  • This sensor uses lookups to determine the status values of one or more channels.

Scanning interval

  • The minimum scanning interval of this sensor is 1 minute.
  • The recommended scanning interval of this sensor is 1 minute.

Multi-platform probe

  • You can add this sensor to a multi-platform probe.

Primary Channel

Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel below the sensor's name. The available options depend on what channels are available for this sensor.

i_round_blueYou can set a different primary channel later by clicking b_channel_primary below a channel gauge on the sensor's Overview tab.

Graph Type

Define how this sensor shows different channels:

  • Show channels independently (default): Show a graph for each channel.
  • Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This generates a graph that visualizes the different components of your total traffic.
    i_round_redYou cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).

Stack Unit

This setting is only visible if you select Stack channels on top of each other above.

Select a unit from the list. PRTG stacks all channels with this unit on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so.

Result Handling

Define what PRTG does with the sensor result:

  • Discard result (default): Do not store the sensor result.
  • Store result: Store the last sensor result in the \Logs\sensors subfolder of the PRTG data directory on the probe system. The file name is Result of Sensor [ID].log. This setting is for debugging purposes. PRTG overwrites this file with each scanning interval.

i_podThis option is not available when the sensor runs on the hosted probe of a PRTG Hosted Monitor instance.

i_round_blueIn a cluster, PRTG stores the result in the PRTG data directory of the master node.

Inherited Settings

By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click b_inherited_enabled under the corresponding setting name to disable the inheritance and to display its options.

i_square_cyanFor more information, see section Inheritance of Settings.

Channel List

i_round_blueWhich channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.



Container Type

The container type

  • Up status: Aggregate, Foreign, Labelmaint, Maintenance, Shared, Spare, Unsupported, Remote, Mediator
  • Warning status: Unassigned, Unknown
  • Down status: Broken
  • Unknown status: Channel Value Not Set


In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status

Path Error Count

The number of path errors

i_round_blueThis channel has a default limit:

  • Upper error limit: 0
