PRTG Manual: NetApp System Health Sensor
IMPORTANT INFORMATION |
---|
This sensor supports NetApp cDOT as of version 8.3 or ONTAP from versions 9.0 to 9.12. If you use ONTAP as of version 9.6, we recommend that you use the NetApp System Health v2 sensor. |
The NetApp System Health sensor monitors the health of a NetApp cDOT or ONTAP storage system accessing the application programming interface (API) via the Simple Object Access Protocol (SOAP).
For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.

Consider the following remarks and requirements for this sensor:
Remark |
Description |
---|---|
Enabled ONTAPI access |
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. If access is disabled, locally use the following command on the cluster console to enable ONTAPI access for the user: services web> modify -vserver clusterd -name ontapi -enabled true This sensor requires administrator rights 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 |
.NET 4.7.2 or later |
This sensor requires .NET 4.7.2 or later from Microsoft on the probe system. In a cluster, install it on every cluster node. If the framework is missing, you cannot create this sensor. For more information, see the Knowledge Base: Which .NET version does PRTG require? |
NetApp versions |
This sensor supports NetApp cDOT as of version 8.3 and NetApp ONTAP as of version 9.0. |
IPv6 |
This sensor supports IPv6. |
Performance impact |
This sensor has a very low performance impact. |
Read-only |
As an alternative to administrator rights, you can add a specific Role Attribute and use read-only rights. |
Credentials |
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. |
Lookups |
This sensor uses lookups to determine the status values of one or more channels. |
Limits |
This sensor has predefined limits for several metrics. |
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
For more information about basic sensor settings, see section Sensor Settings.
Setting |
Description |
---|---|
NetApp Credentials |
Specify which credentials you want to use to connect to the NetApp API:
|
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:
|
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. |
Setting |
Description |
---|---|
System Nodes |
The ID of the system node that this sensor monitors. |
Setting |
Description |
---|---|
Result Handling |
Define what PRTG does with the sensor result:
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. |
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:
|
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. |
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.
Permissions: Alternative to Administrator Rights
If you do not want to provide administrator rights for the ONTAPI user account that you use with the NetApp System Health sensor, you can add a new command to the selected role of the user that makes read-only rights sufficient.
- Edit the Role of this user in the console under Cluster | ClusterX | Configuration | Security | Users.
- Add the command storage aggregate check_spare_low with access control list (ACL) all to the Role Attributes.
With this role attribute, read-only rights are sufficient for the NetApp System Health sensor.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.
Channel |
Description |
---|---|
CPU |
The CPU load (%) This channel is the primary channel by default. This channel has default limits:
|
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 |
Failed Fans |
The number of failed fans This channel has default limits:
|
Failed PSU |
The number of failed power supplies This channel has default limits:
|
Memory |
The memory usage |
Node Health |
The node health
|
NVRAM Battery |
The NVRAM battery status
|
Spare Disks # |
The number of spare disks |
Spare Disks Low |
If spare disks are low as reported by the NetApp
|
Spare Size Usable |
The usable spare size |
Storage Configuration Path |
The storage configuration path that describes the connection of a node
If no storage configuration path is returned, the sensor shows the Up status (N/A) because the availability of the configuration path depends on the NetApp version. |
Temperature |
The temperature status
|
Uptime |
The uptime |
