PRTG Manual: NetApp Volume v2 Sensor

<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: NetApp Volume v2 Sensor

The NetApp Volume v2 sensor monitors a volume 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.

NetApp Volume Sensor

For a detailed list and descriptions of the channels that this sensor can show, see section Channel List.

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
Credentials	This sensor requires credentials for NetApp.
NetApp versions	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 Volume 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.
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:

netapp
ontap
rest

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

NetApp Specific

Setting	Description
Volume Name	The name of the volume that this sensor monitors.
Aggregate Names	The names of the aggregates that contain the volume 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 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.

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
Autogrow	The autogrow status Up status: Can Grow, Off Warning status: Grow Limit Reached 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.
Files Free	The number of files that can be created on the volume
Files Free %	The number of files that can be created on the volume This channel has default limits: Lower error limit: 10% Lower warning limit: 25%
Latest Snapshot	The time since the latest snapshot
Oldest Snapshot	The oldest snapshot age
Physical Bytes Free %	The free physical bytes This channel has default limits: Lower error limit: 10% Lower warning limit: 25%
Size Free	The free size This channel also takes the snapshot reserve space (if set in the ONTAP System Manager) on the volume into account.
Size Free %	The free size (%) This channel is the primary channel by default. This channel has default limits: Lower error limit: 10% Lower warning limit: 25% This channel also takes the snapshot reserve space (if set in the ONTAP System Manager) on the volume into account.
Snapshot	The number of snapshots This channel has a default limit: Upper error limit: 1024 Volumes can contain up to 1023 snapshot copies. The limit of this channel is set to define a fixed size of the gauge that reflects the maximum number of snapshot copies that the volume can contain.
