Consider the following remarks and requirements for this sensor:
Remark |
Description |
---|---|
Performance impact |
This sensor has a high performance impact. Stay below 200 WMI sensors per probe. Above this number, consider using multiple remote probes for load balancing. |
WoW64 |
This sensor requires WoW64 (Windows 32-bit on Windows 64-bit) for target systems that run Windows Server 2016. |
Credentials |
This sensor requires credentials for Windows systems. |
IPv6 |
This sensor supports IPv6. |
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:
- wmifilesensor
For more information about basic sensor settings, see section Sensor Settings.

Description |
---|---|
File Name |
Enter the name of the file that you want to monitor. Enter the full local path. The file must exist on the probe system. The sensor does not support Universal Naming Convention (UNC) paths. |
If Time Stamp Changes |
Define what the sensor does if the time stamp of the file changes:

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.

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 |
File Size |
The file size This channel is the primary channel by default. |
Last Modified |
The time since the last modification of the file |
