Consider the following remarks and requirements for this sensor:
Remark |
Description |
|---|---|
LanmanServer service |
This sensor requires that the LanmanServer service runs on the target system.
|
Quotas |
This sensor only works if no quotas are enabled on the target share. If there are quotas enabled for the user account that this sensor uses to connect to the share, the absolute value is okay, but the percentage variable shows incorrect values. |
Share name |
You can only enter a share name, for example, C$. Do not enter a complete Universal Naming Convention (UNC) name. The sensor takes the server name \\server\ from the parent device. |
IPv6 |
This sensor supports IPv6. |
Performance impact |
This sensor has a medium performance impact. |

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.
|
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.
