Remarks

Consider the following remarks and requirements for this sensor:

Remark

Description

Performance impact

This sensor has a high performance impact. We recommend that you use no more than 200 of this sensor on each probe.

Dell Modular Disk Storage Manager

This sensor requires Dell Modular Disk Storage Manager on the probe system. You must install it on the probe system (on every cluster node, if on a cluster probe). For details about setup, see section More below.

i_round_redCreate this sensor on a device that has the IP address of the SAN configured in the IP Address/DNS Name field of the sensor settings.

i_square_cyanFor more information, see the Knowledge Base: Where do I find the Dell PowerVault Modular Disk Storage Manager for use with my MDi SAN?

IP address

This sensor requires the IP address of the storage area network (SAN) in the settings of the parent device.

Dell PowerVault models

This sensor supports Dell PowerVault MD3000i, MD3420, MD3620i, MD3000f, MD3620f, or MD3820i, and might support other models.

IPv4

This sensor only supports IPv4.

Hosted probe

i_podYou cannot add this sensor to the hosted probe of a PRTG Hosted Monitor instance. If you want to use this sensor, add it to a remote probe device.

Description

Virtual Disk

The name of the virtual disk that this sensor monitors.

Result Handling

Define what PRTG does with the sensor result:

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

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

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.
