PRTG Manual: NetApp LUN v2 Sensor

The NetApp LUN v2 sensor monitors the logical unit number (LUN) of a NetApp storage system via the Representational State Transfer (REST) application programming interface (API) using ONTAP as of version 9.6.

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

Remarks

Consider the following remarks and requirements for this sensor:

Remark	Description
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
NetApp versions	This sensor requires ONTAP as of version 9.6. If you want to use NetApp cDOT as of version 8.3 or ONTAP from version 9.0 to version 9.5, use the NetApp LUN sensor.
Credentials	This sensor requires credentials for NetApp.
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.
Limits	This sensor has predefined limits for several metrics.
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.

Basic Sensor Settings

The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:

lun
netapp
ontap
rest

For more information about basic sensor settings, see section Sensor Settings.

NetApp Specific

Setting	Description
LUN Path Name	The path name of the LUN that this sensor monitors.
Operating System Type	The operating system type of the LUN that this sensor monitors.
Description	The description of the LUN that this sensor monitors.

Sensor Display

Setting	Description
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.

Description

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.

Debug Options

Setting	Description
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. 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.

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.

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.

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 under the corresponding setting name to disable the inheritance and to display its options.

For more information, see section Inheritance of Settings.

Channel List

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

Channel	Description
Bytes Free	The free space This channel has default limits: Lower error limit: 10% Lower warning limit: 25%
Bytes Free %	The free space (%)
Container State	The container status Up status: Online Down status: Aggregate Offline, Error, Volume Offline 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 Read	The number of IOPS read
IOPS Total	The total number of IOPS
IOPS Write	The number of IOPS written
Latency Read	The read latency
Latency Total	The total latency
Latency Write	The write latency
State	The LUN status Up status: Online Down status: Foreign LUN Error, NVRAM Failure, Offline, Space Error Unknown status: Channel Value Not Set This channel is the primary channel by default.
Throughput Read	The number of bytes read
Throughput Total	The total number of bytes read and written
Throughput Write	The number of bytes written
