PRTG Manual: SNMP Cisco UCS Physical Disk Sensor

The SNMP Cisco UCS Physical Disk sensor monitors a physical disk of a Cisco Unified Computing System (UCS) device via the Simple Network Management Protocol (SNMP).

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
IPv6	This sensor supports IPv6.
Performance impact	This sensor has a medium performance impact.
Lookups	This sensor uses lookups to determine the status values of one or more channels.
Add Sensor dialog	The Add Sensor dialog only shows working disks that have the status Up or Warning.

Basic Sensor Settings

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

snmp
snmpciscophysicaldisksensor
ucs

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

UCS Physical Disk

Setting	Description
Disk	The physical disk that this sensor monitors.
Display Name	The display name of the physical disk 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
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.
Operability	The operability status Up status: Auto Upgrade, Operable Warning status: Degraded, Unknown Down status: Accessibility Problem, Bios Post Timeout, Chassis Limit Exceeded, Config, Decomissioning, Disabled, Discovery, Discovery Failed, Equipment Problem, Fabric Connection Problem, Fabric Unsupported Connection, Identify, Identity Unestablishable, Inoperable, Link Activate Blocked, Malformed Fru, Not Supported, Peer Comm Problem, Performance Problem, Post Failure, Power Problem, Powered Off, Removed, Thermal Problem, Upgrade Problem, Voltage Problem This channel is the primary channel by default.
Presence	The connection status Up status: Equipped, Equipped Not Primary Warning status: Equipped Identity Unestablishable, Mismatch, Mismatch Identity Unestablishable, Missing, Down status: Equipped With Malformed Fru, Inaccessible, Not Supported, Unauthorized Unknown status: Empty, Unknown
