Configure Monitored Networks and Domain Sets

Once the Endpoint Agent has been installed, monitored networks and domain sets should be configured to define when and from where the agent should collect data. This article provides instructions for configuring both monitored networks and monitored domain sets.

Add a Monitored Network

Configuring a monitored network enables automatic data collection when the Endpoint Agent resides inside a defined network:

  1. In the ThousandEyes web application, navigate to Endpoint Agents > Browser Session Settings.

  2. Click the Monitored Networks tab.

  3. Click Add New Network.

  4. Enter a network in CIDR format (e.g. 192.150.160.0/24) or an IP address range (e.g. 192.150.160.100-192.150.160.150). If you enter an IP address, the longest matching address block will be looked up. Below the field, a network block containing your current public IP address will be shown.

    RFC 1918 networks (10.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12) cannot be added. Use the network providing the public IP address for the client when it makes connections to the Internet.

    IPv6 addresses cannot be used at this time.

  5. Choose the name for your new network entry.

  6. Select a Monitored Domain Set that should be applied to your new monitored network.

  7. To complete the process, click the Add button.

Repeat the process above to define multiple monitored networks. Configured networks and their corresponding monitored domain sets will be listed under Monitored Networks tab:

Optionally, to configure data collection regardless of agent's current public IP address, click Add New Network and enter the IP address range 0.0.0.0-255.255.255.255. This will add a built-in Network entry All other networks. To delete a monitored network, click the corresponding Trash icon on the right-hand side of the network list.

Add a Monitored Domain Set

Configuring a monitored domain enables automatic data collection when browsing websites within the defined domain:

  1. In the ThousandEyes web application, navigate to Endpoint Agents > Browser Session Settings.

  2. Click the Monitored Domains tab.

  3. Click Add New Monitored Domain Set.

  4. Name your new monitored domain set.

  5. Add one or more domain names into the Monitored Domains field. Don't wildcard your entries - enter the domain suffix only (ie. "thousandeyes.com", rather than "*.thousandeyes.com").

  6. Click Add button to conclude the creation process.

    No data collection occurs against non-monitored domains.
