There are some behind-the-scenes posts that go into more detail on how and why I took the approach that I did. Those can be found here:
- Behind the Scenes – The Lab Build
- Ok, there’s only one so far, but I plan to add more where it makes sense.
With the lab environment built, and the agents installed and online, now it’s time to start actually getting monitoring data through ThousandEyes!
If you haven’t followed along with the previous posts in this series you can find the lab build here: https://www.mytechgnome.com/2022/04/thousandeyes-walkthrough-part-2-lab.html and the agent installation here: https://www.mytechgnome.com/2022/04/thousandeyes-walkthrough-part-3.html
This lab requires version 1.1 of the lab build. Verify the lab you are using is 1.1 or newer. If it’s not, look at the CHANGELOG section near the bottom of the lab build post: https://www.mytechgnome.com/2022/04/thousandeyes-walkthrough-part-2-lab.html
- Open a web browser and navigate to https://www.thousandeyes.com/
- Log into your account
- Click the Hamburger icon in the top left
- Expand Devices
- Click on Device Settings
- There might be a Get Started with Devices splash screen, or it will take you directly to the Devices page.
- On the right in the Basic Configuration enter the scan details
- In Targets enter the following subnet: 10.255.255.0/24
- In the Monitoring Agent drop-down select CS1-1
- Under Credentials click “Create new credentials”
- If the Credentials don’t auto-populate then click the dropdown and select the TE-SNMP that was just created
- Occasionally devices may not be picked up on the first discovery, but if the box is checked to “Save as a scheduled discovery” it will retry every hour
- Click Start Discovery
- Wait for the discovery process to complete – this might take a few minutes
- NOTE: There seems to be a bug in the UI where it displays a “No devices found” error, even though all the devices were discovered.
- Click back to the main section of the page and the Add Devices panel will disappear
- Click the Select All checkbox on the top left of the device list, then click Monitor at the bottom of the page.
- Wait a few minutes for the devices to show Green under the Last Contact column
- Hover over the menu icon in the top left, then under Devices click on Views
- The Device Views will show some metric data on the top, and the topology on the bottom
- Click on Edit Topology Layout
- Devices in the topology view can be moved (drag-and-drop) to better represent the actual topology. Click Done Editing when the device positions match the lab topology.
