PRTG Manual: SNMP NetApp Logical Unit Sensor
The SNMP NetApp Logical Unit sensor monitors the input/output operations per second (IOPS) on a logical unit of a NetApp storage system via the Simple Network Management Protocol (SNMP).

Consider the following remarks and requirements for this sensor:
Remark |
Description |
|---|---|
NetApp versions |
This sensor only supports NetApp versions up to 8.2. |
IPv6 |
This sensor supports IPv6. |
Performance impact |
This sensor has a low performance impact. |
Lookups |
This sensor uses lookups to determine the status values of one or more channels. |
NetApp LUN |
If you use NetApp cDOT 8.3 or NetApp ONTAP as of version 9.0, we recommend that you use the NetApp LUN sensor. |
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
- snmpdiskfreesensor
- snmpnetapp
- snmpnetappdiskfreesensor
For more information about basic sensor settings, see section Sensor Settings.
NetApp Logical Unit Settings
Setting |
Description |
|---|---|
Logical Unit |
The name of the logical unit that this sensor monitors. |
Alignment Monitoring |
Select if the sensor checks the alignment of the logical unit:
|
Volume |
The volume that this sensor monitors. |
Comment |
Comments for the logical unit 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.
|
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.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.
Channel |
Description |
|---|---|
Data Read |
The data read speed |
Data Written |
The data write speed |
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. |
Errors |
The number of errors |
Ops |
The total number of operations
|
Other Ops |
The number of other operations |
Read Ops |
The number of disk read operations |
Status |
The logical unit status
|
Write Ops |
The number of disk write operations |
