Product Announcements

Migration of Transaction (Classic) Tests

In the next release, ThousandEyes will be disabling the ability to create additional transaction (Classic) tests from the product.

ThousandEyes will be working with individual customers as well as making an automated conversion process from within the product console available to assist with the migration process. This tool is expected to be available in May. If you need the ability to create additional transaction (Classic) tests after April 30, contact the ThousandEyes support team.

New Documentation Platform

ThousandEyes is excited to announce the launch of our new website for product documentation. This is the first stage in our efforts to provide users with an improved content experience.

New Features and Enhancements

Cloud and Enterprise Agents

TLS Certificate Expiration and Session Information

ThousandEyes has introduced the ability to alert on certificate expiration and TLS session information. All existing and new HTTP server tests will now include TLS session information such as the certificate chain, TLS version, and cipher suite negotiated in a new slide-out modal that will also include HTTP request and response headers:

In addition to being able to view TLS session information in HTTP Server view, customers can configure alerts for the following new associated metrics:
  • Certificate expiration
  • TLS version
  • Weaker Cipher Suite negotiated
User-added image
For more information, see our TLS Certificates blog.

Certificate chain and session information have also been added to the /v6/web/http-server/{testID}?certificates=1 endpoint. Example output is shown below:
"sslVersion": "TLSv1.2",
        "sslCipher": "ECDHE-RSA-AES128-GCM-SHA256",
        "sslCerts": [
            "notValidAfter": "2020-06-03 12:00:00",
            "notValidBefore": "2018-05-08 00:00:00",
            "subjectName": "",
            "issuerName": "DigiCert SHA2 Extended Validation Server CA",
            "subjectAltNames": [
            "fetchDateInValidCertDateRange": true,
            "daysUntilExpiry": 35
See the developer documentation for more information.

White Node Collapsing in Path Visualization

To improve path visualization page performance, instances with three or more consecutive white (star nodes) in the path visualization will be collapsed into a group by default.

Collapsed white nodes:

  • Pagination has been added to the dashboard “Test Table” widget.
  • The “Shared” dashboard label has been renamed “Shared with others” for dashboards shared across account groups.


  • Browser-based tests have been upgraded from Chromium 68 to Chromium 80.

Endpoint Agents

  • Forwarding loss can now be shown within Endpoint Agent path trace views.
    • Important: This enhancement will be available with the next Client release (currently estimated for May 4th).
  • The Agent Settings page is now paginated to improve usability when managing large numbers of Endpoint Agents.

Internet Insights

  • Added a welcome page to help customers get started with Internet Insights:
    • For subscribers: The content covers key concepts, product areas, and links to existing resources and can be re-launched from the Help menu.
    • For non-subscribers: The Internet Insights navigation menu link now directs users to in-product content instead of opening the product offering page in a new tab.
  • Internet Insights outage alerts are now available via the ThousandEyes v7 API. See the v7 API documentation available at for details.
  • Internet Insights outage alert rule names can now be edited.
  • The Internet Insights destination network filter has been renamed from "Network" to "Destination Network" in order to make it easier to distinguish from the affected interfaces network filter.


Alerts API

  • The ThousandEyes v7 API (preview) now includes the an alerts endpoint. For more information, see the Developer documentation.

Endpoint Agent

  • The last seen IP address of an Endpoint Agent is now available via the API.
  • The Endpoint Agent’s name can now be updated via the API.
  • The username associated with an Endpoint Agent is now available via the API.

Additional Enhancements

  • ThousandEyes has made a change to the Sharing section that lists the Snapshots and Saved Events available. Specifically, we removed the 'Shared with Me' from the Snapshots, as many customers found it confusing to see snapshots that were shared with members of an organization account, in addition to those that were shared with the individual administrator.

Deprecated and Removed Features

Temporary Suspension of Mobile Agents

The ThousandEyes mobile cloud agents introduced in January will be taken offline for the near future in order to make architectural changes that will ensure we provide the best quality data on the optimum networks.

The following agents will be removed on April 30, 2020:
  • Chicago, IL (AT&T Mobile), (T-Mobile), or (Verizon Mobile)
  • New York, NY (AT&T Mobile), (T-Mobile), or (Verizon Mobile)
  • Dallas, TX (AT&T Mobile), (T-Mobile), or (Verizon Mobile)
  • Los Angeles, CA (AT&T Mobile), (T-Mobile), or (Verizon Mobile)
  • San Jose, CA (AT&T Mobile), (T-Mobile), or (Verizon Mobile)

Adobe Flash Support for Transaction Tests

Transaction tests no longer support Adobe Flash-based user workflows.

Bug Fixes


  • An issue occurred where there was a difference between the time shown in the dashboard test table widget when compared to the Test view. This was caused by the widget using UTC rather than the local user time, and has been resolved.
  • In rare instances, an issue occurred where a report snapshot was emailed twice instead of once. This has been resolved.
  • An issue occurred where the "location" filter for Endpoint Agents was presenting either incorrect options or no options at all. This has been fixed.


  • Previously, some customers were unable to run Transaction tests on some Enterprise Agents because another process was binding to port 53 on a network interface created by te-sandboxd. A "warn"-level log will now appear in te-sandboxd when this configuration is detected.
  • Previously, Transaction tests were not able to perform downloads.waitForDownload() commands in a test that is configured to use an HTTP proxy. This has been resolved.
  • Previously, some snapshots of browser-based test data were taking longer than an hour to process. This has been resolved.
  • Previously, in Transaction test views, very long marker names could cause their corresponding durations to appear in the wrong place. Layout and styling adjustments have been made to resolve this error.

Endpoint Agents

  • An issue occurred where several data points were missing or empty when connecting via a Cisco AnyConnect VPN. This has been resolved.
  • Fixed an issue that resulted in an "account mismatch" check misfiring during uninstalls.
  • An issue occurred where an instant test would show “Loading” forever if agents were submitting data, but not for the selected metric. This has been resolved.
  • An error caused the support chat window to be hidden in some views. This has been fixed.
  • An error was caused by the Endpoint Agent link speed being inconsistently calculated. This has been resolved.
