Components of the Collector


Components of the Collector


The Collector is mainly composed of a set of services and libraries that gather information about the devices in your corporate network and their activity. The Collector periodically sends all the gathered information to an Engine, where it is processed and stored. Additional components of the Collector deal with the features provided by optional Nexthink modules. Finally, other components help you with the installation and configuration of the Collector.

Find in this document the description of all the different components of the Collector and the filesystem paths where to find them in the devices of the end users after installation. This article details as well the registry keys and the additional files created or modified during the installation of the Collector.

Registry keys of the Windows Collector

On installation, the Collector creates the following keys in the Registry of Windows:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Nexthink Coordinator
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Nexthink Coordinator\params
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Nexthink Coordinator\Modules\COD

Finally, Windows creates a cached copy of the kernel drivers in two folders whose names start with the name of the drivers (nxtrdrv and nxtrdrv5, respectively) followed by an unique identifier that depends on the version of the driver itself. Find the folders here:

  •  %windir%\System32\DRVSTORE

The Nexthink Reporter tool creates its logs and reports here:

  •  %temp%\nxtreporter[reportID].log
  •  %temp%\nxtreport-[hostname]-[reportID].zip
