PRTG Manual: NetApp Physical Disk v2 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

Credentials

This sensor requires credentials for NetApp.

Channels

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.

IPv6

This sensor supports IPv6.

Performance impact

This sensor has a very low performance impact.

Lookups

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.

Disk Name

The name of the physical disk that this sensor monitors.

Home Node Name

The home node name of the physical disk that this sensor monitors.

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.

You can set a different primary channel later by clicking 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.
  You 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 sensor result and the last response 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.

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

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

Container Type

The container type

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

Downtime

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.

IOPS Total

The number of IOPS

Latency

The latency

Path Error Count

The number of path errors

This channel has a default limit:

• Upper error limit: 0

Power On Hours

The total time that the disk has been spinning

Throughput

The throughput

This channel is the primary channel by default.
