<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: NetApp System Health v2 Sensor
The NetApp System Health v2 sensor monitors the health of a node of a NetApp storage cluster 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. This sensor now requires permissions for the ONTAP REST API and credentials for NetApp in settings that are higher in the object hierarchy, for example, in the settings of the parent device.
This sensor is in beta status. The operating methods and the available settings are still subject to change. Do not expect that all functions work properly, or that this sensor works as expected at all.

Remarks
This sensor requires that the Beta Sensors experimental feature is enabled.
This sensor requires credentials for NetApp in settings that are higher in the object hierarchy, for example, in the settings of the parent device.
This sensor requires an ONTAP System Manager user account with specific access rights.
This sensor requires permissions for the ONTAP REST API.
This sensor supports 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 System Health sensor instead.
This sensor requires ONTAP 9.11 for some channels.
This sensor supports the IPv6 protocol.
This sensor has a very low performance impact.
This sensor uses lookups to determine the status values of one or more channels. This means that possible states are defined in a lookup file. You can change the behavior of a channel by editing the lookup file that the channel uses. For details, see section Define Lookups.
Detailed Requirements
Requirement
Description
Enabled Beta Sensors experimental feature
This sensor requires that the Beta Sensorsexperimental feature of PRTG is enabled.
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 sensorrequires 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
Add Sensor
The Add Sensor dialog appears when you manually add a new sensor to a device. It only shows the settings that are required to create the sensor. You can change nearly all settings on the sensor's Settings tab after creation.
NetApp Specific
The settings that you select in the Add Sensor dialog are valid for all sensors that you create when you finish the dialog.
Setting
Description
Node Name
Select the nodes that you want to monitor. PRTG creates one sensor for each system node that you select.
Enable check boxes in front of the respective lines to select the items. Use the check box in the table header to select all items or to cancel the selection. In large tables, use the search function in the upper-right corner.
Basic Sensor Settings
Click the Settings tab of a sensor to change its settings.
If the name contains angle brackets (<>), PRTG replaces them with braces ({}) for security reasons. For more information, see the Knowledge Base: What security features does PRTG include?
This setting is for your information only. You cannot change it.
Tags
Enter one or more tags. Confirm each tag with the Spacebar key, a comma, or the Enter key. You can use tags to group objects and use tag-filtered views later on. Tags are not case-sensitive. Tags are automatically inherited.
It is not possible to enter tags with a leading plus (+) or minus (-) sign, nor tags with parentheses (()) or angle brackets (<>).
For performance reasons, it can take some minutes until you can filter for new tags that you added.
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
netapp
ontap
rest
Priority
Select a priority for the sensor. This setting determines the position of the sensor in lists. The highest priority is at the top of a list. Choose from the lowest priority () to the highest priority ().
Usually, a sensor connects to the IP Address/DNS Name of the parent device. See the device settings for details. For some sensors, you can explicitly define the monitoring target in the sensor settings.

Node Name
Shows the name of the node that this sensor monitors.
PRTG shows this value for reference purposes only. If you need to change this value, add the sensor anew.

Description
Primary Channel
Select a channel from the list to define it as the primary channel. In the device tree, the last value of the primary channel is always displayed 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 different channels are shown for this sensor:
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 enable Stack channels on top of each other as Graph Type. Select a unit from the list. All channels with this unit are stacked 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
Result Handling
Define what PRTG does with the sensor result:
Discard result: 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 names are Result of Sensor [ID].txt, Result of Sensor [ID].Data.txt, and Result of Sensor [ID].log. This setting is for debugging purposes. PRTG overwrites these files 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.
The minimum scanning interval of this sensor is 1 minute.
The recommended scanning interval of this sensor is 1 minute.
Scanning Interval
For more information, see section Root Group Settings, section Scanning Interval.
Schedules, Dependencies, and Maintenance Window
You cannot interrupt the inheritance for schedules, dependencies, and maintenance windows. The corresponding settings from the parent objects are always active. However, you can define additional schedules, dependencies, and maintenance windows. They are active at the same time as the parent objects' settings.
Schedules, Dependencies, and Maintenance Window
For more information, see section Root Group Settings, section Schedules, Dependencies, and Maintenance Window.
Access Rights

Channel Unit Configuration
Which channel units are available depends on the sensor type and the available parameters. If no configurable channels are available, this field shows No configurable channels.
Channel Unit Configuration
For more information, see section Root Group Settings, section Channel Unit Configuration.
Channel List
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.
