<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> 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).

Remarks

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: Do not check alignment (default) Check alignment (if available) You cannot change this value after sensor creation.
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. 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.

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
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 This channel is the primary channel by default.
Other Ops	The number of other operations
Read Ops	The number of disk read operations
Status	The logical unit status Up status: Online Down status: Offline
Write Ops	The number of disk write operations
