Directory Sensor (Windows)

With the help of the Directory Sensor you can monitor local as well as distant folders and their properties of a Windows system.

Since the examination of a folder can be time-consuming based upon size, the disk space manager SpaceObServer (further information: here) can be used if it is installed. When the folder is requested for the first time, a new scan will be executed by SpaceObServer (incl. creation of a schedule), if needed. The data will be saved in a separate database and then delivered to ServerSentinel.


If a scan already exists for the target folder, please make sure an appropriate schedule is defined because the sensor obtains all its data from SpaceObServer in this case. An automatic creation of a schedule is not available at the moment.

If SpaceObServer is not installed, the folder will be opened manually. Note that that check interval should be set based upon folder size.

This feature is only available if SpaceObServer V6.0 Enterprise Edition (x64) or SpaceObServer V6.0 Remote Client (x64) in installed on the same host as the ServerSentinel service.
