Collector configuration tool for Windows

Overview

Nxtcfg is a small console application that reads and modifies the configuration parameters of Collector. Run Nxtcfg with administrator privileges.

Installation

By default, the Nxtcfg tool is installed along with Collector when installing the Collector MSI. Here is the absolute file path:

C:\Windows\System32\nxtcfg.exe

If not required, add the option CFG_INSTALL=0 to the MSI command line when installing the Collector.

Configuration parameters

Modifying some of the parameters requires a restart of Collector for all the changes to take effect. Rebooting the device forcefully restarts all Collector components as well. For each parameter, this is specified by the values in the column Restart required of the parameters table:

No No reboot or component restart is required.
Yes Collector restart or device reboot is required.

Nxtcfg in remote actions

Because Collector communicates with the Nexthink instance when running remote actions, it is not recommended to change any of the configuration parameters of Collector from a remote action. Thus, refrain from modifying any of the following configuration parameters when running nxtcfg.exe within a remote action:

ip
tcp_port
customer_key

For the same reason, do not stop or restart Collector with nxtcfg.exe using a remote action. Directly stopping or restarting Collector abruptly ends the communication between Collector and the Nexthink instance, resulting in Collector losing its state with respect to the remote action. Once Collector is up again, it executes the remote action from the beginning, potentially creating an infinite loop.

Instead, if you need to modify some Collector settings from a remote action that requires a restart, use the following code in the script of the remote action:

To stop Collector:

Stop-Service -Name "Nexthink Service" -Force
Stop-Service -Name "nxtrdrvwfp" -Force
Stop-Service -Name "nxtrdrv" -Force

To start Collector:

Start-Service -Name "nxtrdrv"
Start-Service -Name "nxtrdrvwfp"
Start-Service -Name "Nexthink Service"

Setting the customer key

Collector uses the customer key to validate the identity of the Nexthink instance and securely communicate with it via TLS. If that security parameter changes, you must adjust the configuration of your Collector instances.

The parameter customer_key is special because it does not admit a direct value as an argument but as a path to a text file holding the actual value of the customer key.

To set the customer key and root certificate, type in the following command:

nxtcfg.exe /s customer_key="C:\Nexthink-customer-key.txt" The instruction above assumes that you placed the files in the root directory of your C: drive

When listing the customer_key parameter with the /l option of Nxtcfg, the complete customer key is not displayed. Only the first few characters are shown. These characters are usually enough to identify the key while keeping the list of the other parameters readable.
