Release Notes: May 2023


Ubuntu 18.04 LTS End of Support

Ubuntu 18.04 LTS is now in the End of Support stage of its lifecycle. ThousandEyes will no longer provide technical support, nor guarantee software updates (including bug fixes) for customers still running Enterprise Agents on Ubuntu 18.04.
The OS will reach End of Life on June 30, 2023. Prior to this date, agents will continue running tests and submitting data. After this date, the agents will no longer be able to communicate with our platform.
In-place upgrades for ThousandEyes Enterprise Agents running Ubuntu 18.04 LTS ("Bionic") are supported for virtual appliances, Intel NUCs, and Raspberry Pis, and instructions are available for upgrading a single agent, bulk agents, and agents using proxies.
To review the upgrade instructions, see Upgrade Ubuntu 18.04 Bionic-Based ThousandEyes Appliances.

IPv6 Enabled for

In preparation for expanding IPv6 support for agent communications to additional platforms, we will be adding IPv6 addresses and a new AAAA record for This endpoint is used to serve container image downloads when you go through the add agent workflow within the ThousandEyes web application.
This change will occur on May 18th, 2023. As this endpoint is CDN hosted, the IPv6 addresses it receives will be dynamic.


Unification of Endpoint Agent Test Settings in US region

As previously communicated, on May 2nd, 2023 we successfully enabled the new monitoring settings in the EU region. We will now be proceeding with the unification of Endpoint Agent test settings for the US region, beginning on Wednesday, May 17th, 2023, at 10:00am UTC.
This migration will affect both EU and US regions. For more information, subscribe to the maintenance window request.

2023-05-10 Bug Fixes

  • Fixed a bug that was preventing snapshots from showing the correct time frame when the "Relative Time Frame" was selected for a widget. This has been corrected for widgets in snapshots to show the selected relative time frame.
  • Resolved a bug when creating an alert suppression window that would erroneously display the message “The suppression window must start at least 2 minutes from now” even if the window starts at a future date.
  • Fixed an issue that was showing inconsistent dates or months in the time selector for the "Fixed Time Interval" selection in dashboards when the user's default Web Interface timezone is set to UTC (via the user's setting in Account Settings > Users and Roles > Profile > Time Zone).


Introducing the AppDynamics Bi-Directional Integration

Applications are the critical front door for your business. However, ensuring flawless application experience for your customers is more complicated than ever. Modern applications are built on top of massively complex and decentralized architectures, meaning that a small issue in one service can have a significant effect on the overall customer experience. You need holistic visibility into your environment, from the application all the way to the end user.
Introducing the Bi-Directional Integration with AppDynamics! This integration brings real-time correlation of network metrics together with application performance data inside ThousandEyes. You will be able to see and understand every dependency that contributes to the performance of your application, allowing you to resolve issues more quickly – ultimately leading to a better user experience and improved business outcomes.
As part of the integration, you will have access to Views 2.0 and its Dependent Applications tab. This tab automatically presents AppDynamics’ health status in context with the associated network test data, as well as your application service dependencies. Using this tab, you can easily click directly through to AppDynamics!
Views 2.0 is a major upgrade to our ThousandEyes platform, which offers improved visualization capabilities, such as:
  • multi-metric comparison
  • agent overlays on timelines
  • round-by-round keyboard navigation
These enhancements streamline troubleshooting and will improve your user experience.
For detailed instructions on how to create a bi-directional integration with AppDynamics, see AppDynamics Integration.
If at any time you would like to revert to your previous Views experience, you can click the toggle at the top right of the page to change to Views 1.0, or use the ... pull-down menu to modify your default views.
This integration is currently only available for the ThousandEyes US region. It will be made available for the EU region in a coming release.

Introducing ThousandEyes for OpenTelemetry

ThousandEyes for OpenTelemetry comprises streaming API functionality with data delivered in a standardized metrics format (OTLP), alongside a tagging mechanism to facilitate deep correlations using ThousandEyes data. With ThousandEyes for OpenTelemetry, enterprises can now rapidly maximize the value of their complex and varied datasets to access insights specific to their business needs.

What Is OpenTelemetry?

OpenTelemetry is an open-source, vendor-neutral observability framework that provides a standard way of collecting, processing, and exporting telemetry data in a standardized format. It aims to simplify the collection of monitoring data and increase the interoperability of monitoring tools.

Introducing Test Templates

ThousandEyes helps you monitor the critical infrastructure you depend on to deliver customer experiences and business outcomes. You achieve this by setting up tests that give you real-time visibility into internet-enabled applications and networks. However, there are many ways to set up tests, and the multitude of configuration options often leads to uncertainty. To give you confidence that you have set up monitoring to your critical services in the best possible way, we are introducing test templates.
Test templates allow users to deploy a suite of ThousandEyes suggested best-practice test suites for common use cases such as monitoring a web server, as well as for popular third-party applications such as Cisco Webex. When you use a test template, you can quickly deploy the monitoring resources that are best suited to your use case, with just a few button clicks.
Templates take the guesswork out of setting up your environment, by making it dead simple to monitor mission-critical services based on ThousandEyes prescribed best practices. This feature is now generally available. Every ThousandEyes user now has access to templates at Cloud & Enterprise Agents > Test Settings via the Add New Test > Add from Template dropdown. This feature is also now generally available via the ThousandEyes Public API v7.
For more information, see Test Templates.
