PRTG Manual: Redfish Virtual Disk Sensor

Credentials

This sensor requires credentials for Redfish in settings that are higher in the object hierarchy.

IPv6

This sensor supports IPv6.

Performance impact

This sensor has a very low performance impact.

Lookups

This sensor uses lookups to determine the status values of one or more channels.

Redfish support

Supporters of the Redfish standard include Dell, Eaton, Emerson, Fujitsu, HPE, Intel, Lenovo, NetApp, Supermicro, and VMware.

Multi-platform probe

You can add this sensor to a multi-platform probe.

Knowledge Base

Knowledge Base: I want to know which of my systems support the PRTG Redfish sensors. Can you help me?

Virtual Disk Name

The name of the virtual disk that this sensor monitors.

Capacity

The capacity of the virtual disk that this sensor monitors.

RAID Level

The RAID level of the virtual disk that this sensor monitors.

Physical Disks Count

The number of physical disks connected to the virtual disk that this sensor monitors.

System Name

The name of the system that the virtual disk belongs to.

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.

Result Handling

Define what PRTG does with the sensor result:

• Discard result (default): Do not store the sensor result.
• Store result: Store the sensor result and the last response in the \Logs\sensors subfolder of the PRTG data directory on the probe system. The file name is Result of Sensor [ID].log. This setting is for debugging purposes. PRTG overwrites this file with each scanning interval.

This option is not available when the sensor runs on the hosted probe of a PRTG Hosted Monitor instance.

In a cluster, PRTG stores the result in the PRTG data directory of the master node.

Capacity

The capacity of the virtual disk

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.

Physical Disks "Critical"

The number of physical disks in the critical status

This channel has a default limit:

• Upper error limit: 0

Physical Disks "Offline"

The number of physical disks in the offline status

This channel has a default limit:

• Upper error limit: 0

Physical Disks "OK"

The number of physical disks in the OK status

Physical Disks "Warning"

The number of physical disks in the warning status

This channel has a default limit:

• Upper error limit: 0

Virtual Disk Status

The virtual disk status

• Up status: OK
• Warning status: Warning
• Down status: Critical
• Unknown status: Offline / Absent

This channel is the primary channel by default.
