For customers requiring a turnkey solution, the ThousandEyes Enterprise Agent can be installed on an off-the-shelf hardware such as the Intel NUC. The combination provides a convenient form-factor that is easily shipped to branch offices, partner sites, and other environments, where provisioning only requires a power and network connection. A downloadable ISO image is used to install Linux Ubuntu LTS, the ThousandEyes Enterprise Agent and management software onto the Intel NUC.
This article details the hardware requirements and process required to commission the ThousandEyes Enterprise Agent on an Intel NUC.

Note that the custom download will include the Account Group Token required for the Agent to register itself to the ThousandEyes system.
Click the Generate button. It may take take between 15 and 30 minutes to generate the image. An email will be generated once the image is ready to be downloaded.
The ISO image can be copied to a USB disk (flash drive) and used as a bootable media on the Intel NUC. The following sections describe the process of creating the bootable USB disk on Mac OS X and Windows.
Mac OS X / Linux instructions
- Insert a USB disk that is at least 1GB in size, into a USB port on the Mac. The disk’s content will be overwritten.
- Open a terminal window
diskutil list(OS X) or
fdisk -l(Linux) and identify the physical disk you’re interested in imaging. It should be
/dev/diskN(OS X) or
/dev/sdN(Linux). In the example below, I have a 1GB USB disk in my Mac's USB port:
dave@schadenfreude ~/Downloads> diskutil list /dev/disk0 (internal, physical): #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *500.3 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_CoreStorage Macintosh HD 499.4 GB disk0s2 3: Apple_Boot Recovery HD 650.0 MB disk0s3 /dev/disk1 (internal, virtual): #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Macintosh HD +499.1 GB disk1 Logical Volume on disk0s2 DCA39E1F-1CB4-4386-8E67-0AD63B4A069D Unencrypted /dev/disk2 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *1.0 GB disk2 1: Windows_FAT_32 UBUNTU-SERV 1.0 GB disk2s1
diskutil unmountDisk /dev/diskN(OS X) or
umount /dev/sdN(Linux) to unmount the device (replace
Nwith the actual disk number from the output above):
dave@schadenfreude ~/Downloads> diskutil unmountDisk /dev/disk2 Unmount of all volumes on disk2 was successful
Next, write the image to disk. Run
sudo dd if=<path_to_downloaded_iso> of=/dev/diskN, wait until it completes:
dave@schadenfreude ~/Downloads> sudo dd if=thousandeyes-pa-1.9.100.iso of=/dev/disk2 1175552+0 records in 1175552+0 records out 601882624 bytes transferred in 267.718384 secs (2248193 bytes/sec)
The following instructions are based on Rufus, an open-source application for creating bootable USB flash drives.
- A copy of Rufus can be obtained from here.
- Start Rufus.
- Connect a USB drive that is at least 1GB in size. The disk’s content will be overwritten. If there is only one USB drive on the Windows system, Rufus will automatically selects it and it will be displayed under Device. Otherwise, use the down-arrow to select the desired USB drive.
- Click SELECT and browse to select the downloaded ISO image. In the above screen shot, the filename of the selected image is "thousandeyes-pa-0.162.iso."
- The screen shot above shows the default settings and they can be left as is. Note that the Cluster size default will vary depending on the size of the USB drive. Leave it to the selected default size.
- Click START.
- On the next screen, select "Write DD Image mode," click OK. DD Image Mode is recommended format.
- Click OK to start the boot disk creation.
- When the process completes, remove the USB drive.
The following are intended to be a check list of configurations required for the ThousandEyes application. The reader should consult the appropriate Intel documentation for the applicable procedures.
- Intel documentation can be found here.
- BIOS update files for the Intel NUC can be found here.
- Check that the display (monitor) used with the NUC are compatible. Check on the Intel documentation. To verify, power up the NUC with the monitor connected, if the Intel splash screen can be seen, the monitor is compatible.
- On the NUC, check that the BIOS version is current. If not the most current, upgrade to the latest version.
- The appliance is intended to the an always-on device. Verify that the following are set in the BIOS:
- UEFI Boot Support should be disabled.
- After Power Failure setting should be set to Last State or Power On.
- Verify that the installation environment requirements are satisfied.
- Insert the bootable USB disk in one of the USB slots on the NUC.
- Power up the NUC.
- Tap the F10 key (on the keyboard) to force the BIOS to enter the "Boot" menu..
- On the boot device menu, use the arrow keys to select the USB drive and press <Enter>.
On booting from the USB drive, the installation process will start automatically.
Nouser intervention is required, The initial phase will progress fairly quickly, a progress bar will narrate the progress. The final phase is shown by the "Finishing the installation" screen, "Running preseed," the progress bar will show "14%." The installation process are downloading the required software packages. This screen may remain in this state for about 15 minutes, depending on the speed of the network interface and the delays to the download server. Do not power off the NUC. Leave it until it automatically powers off.
- On completing the installation, the NUC will automatically power off.
- Power on the NUC. After the unit boots, the "ThousandEyes Virtual Appliance" screen (shown below) will be displayed. The IP address displayed depends on the network environment of the NUC. Note the provided username and password.
- Using a browser, access the provided URL (IP address), and log in using the provided username and password.
- The user will be taken to the Appliance Access screen to change the default password.
- Skip this step if the installation is a Custom Appliance, as the Account Group Token is included in the image.
- For information on the other parameters, consult the Knowledge Base "How to set up the Virtual Appliance," available here.
- Verify on the Status screen that all diagnostics are green. Follow up and correct any faults shown on the Status screen.
- If network related parameters were changed, for example disabling IP V6 support, reboot the Agent, through the GUI and verify that all the diagnostics are green.
- The Enterprise Agent should now appear in the Cloud & Enterprise Agents> Agent Settings> Enterprise Agents page of the ThousandEyes portal.
A USB drive is plugged in, tapping F10 at power-up, on the "Boot" BIOS screen, USB drive is not recognized as a bootable device.
Resolution: Disable UEFI boot support.
Check that the BIOS version is current. If not current, upgrade to the latest version.
Ubuntu installation fails with a "blue screen" showing "Malformed IP Address."
Resolution: Verify that the Ethernet connection to the NUC has a link signal. Verify that the Link LED on the RJ-45 port is lit.
Verify that there is a DHCP server on the network (broadcast domain) that the NUC is connected to.
Ubuntu installation fails with "No Root File System Defined" message. This situation can occur if USB devices are attached to the NUC via a USB hub.
Resolution: Do not use USB hub to connect keyboard and USB flash drive to the NUC.
The expected blue "ThousandEyes Virtual Appliance" management screen is not displayed. Instead, a black screen with "
thousandeyes-va login:" prompt is shown.
This is a symptom of an unsuccessful installation. The agent is missing the
te-pa package which, in addition to the web admin interface, provides the physical console functionality.
Resolution: Components of the Virtual Agent are missing. Most likely caused by the lack of non-proxied and unrestricted access to the internet during the appliance installation. Reinstall the appliance in an environment that satisfies the requirements listed in the Installation environment requirements.
When the installation completes, keypresses are not recognized.
Resolution: Most likely incomplete installation. Reinstall the appliance in an environment that satisfies the requirements listed in the Installation environment requirements.
