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. Create 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. For 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 |
You 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. |
The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:
- powervault
For more information about basic sensor settings, see section Sensor Settings.

Virtual Disk |
The name of the virtual disk that this sensor monitors. |
Result Handling |
Define what PRTG does with the sensor result:
In a cluster, PRTG stores the result in the PRTG data directory of the master node. |

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:
|
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. |
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.
Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.
