This sensor supports NetApp cDOT as of version 8.3 or ONTAP from versions 9.0 to 9.12. If you want to use ONTAP as of version 9.6, use the NetApp LUN v2 sensor.
The NetApp LUN sensor monitors the logical unit number (LUN) of a NetApp cDOT or ONTAP storage system accessing the application programming interface (API) via the Simple Object Access Protocol (SOAP).

Remarks
The ONTAPI user account that you use with this sensor requires access to the DATA ONTAP API (ONTAPI) so that the sensor can request data from it. The access is enabled by default.
For this sensor, read-only user rights are sufficient for the ONTAPI user account that you use to access ONTAPI. Modify or add this user with a suitable role in the console under Cluster | ClusterX | Configuration | Security | Users
This sensor requires.NET 4.7.2 or later from Microsoft on the probe system.
This sensor supports NetApp cDOT as of version 8.3 and NetApp ONTAP as of version 9.0.
This sensor supports IPv6.
This sensor has a very low performance impact.
You can define NetApp API credentials (User Name and Password) in the credentials for Windows systems settings of the parent device. This way, you do not need to individually enter credentials for each NetApp sensor that you add to the same device.
This sensor uses lookups to determine the status values of one or more channels.
Detailed Requirements
Requirement
Description
Enabled ONTAPI access
NetApp sensors require access to ONTAPI for the utilized user account. This is enabled by default. If access is disabled, locally use the following command on the cluster console to enable ONTAPI access for the user:
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:
cdot
netapp
ontap
soap
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 ().
NetApp Connection

Setting
Description
NetApp Credentials
Specify which credentials you want to use to connect to the NetApp API:
Use explicit credentials: Use individual NetApp API credentials.
Use Windows credentials from parent device: Use the credentials (User Name and Password) in the parent device settings in section Credentials for Windows Systems. Defining credentials in the parent device is useful if you add several NetApp sensors to this device because you do not need to individually enter credentials for each NetApp sensor.
User Name
This setting is only visible if you select Use explicit credentials above.
Enter a user name for access to the NetApp API. Enter a string.
Read-only rights for this ONTAP user account are sufficient.
Password
This setting is only visible if you select Use explicit credentials above.
Enter the password of the user for access to the NetApp API. Enter a string.
Port
Enter a port number on which you can access the NetApp API. Enter an integer. The default port is 443.
Connection Security
Define if the connection to the NetApp API is Secure Sockets Layer (SSL)/Transport Layer Security (TLS) secured:
HTTP: Use an unsecured HTTP connection.
HTTPS: Use a secure connection to the defined port to send the query.
Timeout (Sec.)
Enter a timeout in seconds for the request. Enter an integer. The maximum timeout value is 900 seconds (15 minutes).
If the reply takes longer than this value, the sensor cancels the request and shows a corresponding error message.

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 names are 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.

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 select Stack channels on top of each other above.
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.
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 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 (default).

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

Up status: Online
Down status: LUN has been automatically taken offline due to a media error on the associated foreign LUN, LUN has been automatically taken offline due to an NVRAM failure, LUN has been automatically taken offline due to insufficient space
Unknown status: LUN is administratively offline or a more detailed offline reason is not available
