Remarks

Consider the following remarks and requirements for this sensor:

Remark	Description
Dell OpenManage Server Administrator or iDRAC 7	This sensor requires Integrated Dell Remote Access Controller (iDRAC) 7 or the Dell OpenManage Server Administrator (OMSA) on the target system. Make sure that you enable SNMP in the OMSA. For more information, see the Knowledge Base: What do I need to monitor Dell servers? You can also monitor Dell PowerEdge servers with this sensor via iDRAC 7.
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.
Knowledge Base	Knowledge Base: What do I need to monitor Dell servers? Knowledge Base: I can't add Dell PowerEdge sensors to PRTG. What can I do? Knowledge Base: My Dell PowerEdge sensor fails to validate disks and I can't add it. What can I do?

Basic Sensor Settings

The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:

dell
physicaldisk
snmpdell
snmpdellphysicaldisksensor

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

Dell PowerEdge Physical Disk Settings

Setting	Description
Disk	The physical disk that this sensor monitors.
Data Source	The interface that PRTG uses to get monitoring data. This is either Dell OMSA or iDRAC.

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
Component Status	The component status Up status: OK Warning status: Non Critical Down status: Critical, Non Recoverable, Other, Unknown
Disk State	The disk status Up status: Non-Raid, Online, Ready Warning status: Foreign Down status: Blocked, Critical, Failed, Non Recoverable, Other, Removed, Unknown This channel is the primary channel by default.
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
Roll Up Status	The roll up status Up status: OK Warning status: Non Critical Down status: Critical, Non Recoverable, Other, Unknown This channel requires that Dell OMSA is installed on the target system.
S.M.A.R.T. Warning	The S.M.A.R.T. warning status Up status: No Down status: Yes
