<%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.

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
  • Check alignment (if available)

i_round_blueYou cannot change this value after sensor creation.

Volume

The volume that this sensor monitors.

Comment

Comments for the logical unit that this sensor monitors.

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.

i_round_blueYou can set a different primary channel later by clicking b_channel_primary 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.
    i_round_redYou 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 b_inherited_enabled under the corresponding setting name to disable the inheritance and to display its options.

i_square_cyanFor more information, see section Inheritance of Settings.

Channel List

i_round_blueWhich 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

i_round_blueThis 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
