Set Up Automatic Export

Aim: To set up automatic export on the Server PC.

Before You Begin

When automatic export is enabled, your session will be automatically exported, once a session is finalized. Exported files will be in the folder that you specify in the commands run below.

Note:

• Export can take some minutes if you have a longer recording.
• The base folder will contain a subfolder named after your session and that folder contains the exported CSV files and video files plus ready.log file.
• The files will not be zipped.
• Files will be downloaded to the Server PC.

Procedure

Automatic export is by default disabled. There are 2 ways to enable it, permanently or temporarily.

Permanently

Choose this method if you want to always use NoldusHub with automatic export.

1. Double-click the batch file StopNoldusHub.
2. Start Command Prompt.
3. Enter setx /M AUTOMATEDEXPORT_FOLDER "yourfolder". If you would like to disable automatic export, follow the same steps before and after this step, but enter REG delete "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /F /V AUTOMATEDEXPORT_FOLDER instead.
4. Double-click the batch file StartNoldusHub.
5. Export is ready when ready.log appears in your folder.

Temporarily

Choose this method if you want to try out automatic export or if you don't want to modify your environment.

1. Double-click the batch file StopNoldusHub.
2. Start Powershell Command Prompt.
3. Enter .\StartNoldusHub.ps1 -automatedexportfolder "yourfolder".
4. Export is ready when ready.log appears in your folder.

NTP Synchronization of Multiple Servers

Aim: To set up the NTP synchronization when there are multiple servers used.

Note: This chapter is specific for when multiple servers are used. If you have only one server, you can ignore this chapter.

Procedure

1. Modify Group Policy:
   • Open Group Policy Editor.
   • Go to: Local Computer Policy > Computer Configuration > Administrative Templates > System > Windows Time Server > Time Providers.
   • Double-click Configure Windows NTP Client.
   • Select Enabled.
   • NTP Server: IpaddressORNameOfNTPServer,0x08
   • Type: NTP
   • Double-click Enable Windows NTP Client.
   • Select Enabled.
2. Restart the Computer: Local Computer Policy changes only take effect after a restart.
3. Check Status:
   • w32tm /query /source — To check if the group policy is applied.
   • w32tm /stripchart /computer:IpaddressORNameOfNTPServer — To track the offset between the client and the NTP server.
   • w32tm /resync — To force a synchronization if the offset is too high.

Windows Update Policy

Aim: To keep Windows up to date without the updates interfering with the functioning of NoldusHub.

Server

Windows Server OS is designed to run services 24/7, so it will not install updates automatically. Therefore, as a system administrator, you will need to take action yourself and plan the OS updates.

Participant PC

It is recommended to stop the Windows update maintenance and to perform the updates manually. It is possible to set the active hours for the Participant PC so the updates will install after active hours or upon shutdown. However, in this case, the updates will still be downloaded during the active hours. This download can interfere with the N-Linx agent, which can result in difficulties with your measurements or data loss.

To stop automatic updates and get notified when an update is available to download, follow these steps:

1. Open Local Group Policy Editor. To do so, type Edit Group Policy in Start or taskbar search box and press Enter.
2. Navigate to the following policy: Computer Configuration > Administrative Templates > Windows Components > Windows Update > Manage End User Experience.
3. Double-click on the policy labeled Configure Automatic Updates on the right side to open its properties.
4. Select Enabled option. Under Configure Automatic Updating, select the second option labeled Notify for Download and Auto Install. Do not change the rest of the settings.
5. Click the Apply button.

Reference

IP Addresses

Aim: To find an IP address or to enter a fixed IP address for the server.

To Find an IP Address

1. Open the Windows Start menu and type IP address.
2. Click on the Change Ethernet Settings tile that appears. Under Ethernet, click the Ethernet connection of your network. Do not use the HyperV Ethernet connection. This is a virtual ethernet connection for the installation files.
3. In the window that appears, the IP address of the PC is shown in the IPv4 address field.
