New ThousandEyes Login Experience
The enhanced ThousandEyes login experience is now live. This update simplifies the login process and improves account security.
What's New:
Automated Detection – After you enter your email address, ThousandEyes automatically detects your authentication method based on your user permissions and organization settings. You no longer need to manually select Single Sign-On (SSO).
Enhanced Security – The "Keep me logged in" option has been removed to strengthen account security.
Updated SSO Behavior – Login behavior now adapts to your organization’s SSO configuration and user permissions. Depending on your default organization settings, you may be redirected automatically to your identity provider (IdP) or given the option to choose between SSO and local login.

Improved Tag Attribute Handling with Advance Enforcement Notice for OpenTelemetry Streams
As part of ongoing improvements to OpenTelemetry (OTel) integration, ThousandEyes has released a temporary update to how non-compliant tags are handled in streamed telemetry data.
What’s Changing (Effective Immediately)
Tags that do not conform to the OpenTelemetry naming recommendations for attributes (for example, containing spaces or invalid characters) will continue to be included in telemetry streams only if they are referenced in a stream’s
tagMatchconfiguration.All other non-compliant attributes will be dropped from the streamed data.
This change is intended to preserve compatibility with existing integrations during the transition period.
Upcoming Breaking Change (Effective September 2025)
Starting in September 2025, ThousandEyes will enforce full compliance with OpenTelemetry attribute naming requirements.
All non-compliant tags, including those used in
tagMatch, will be dropped from telemetry streams.Any associated test data (metrics and traces) containing invalid attributes will be excluded entirely from the stream.
For all metric and trace datapoints, only valid tags will be included in the attributes. Invalid attributes from agents or tests will be removed.
Action Required
To avoid data loss and ensure continued compatibility, update your tags to meet the OpenTelemetry naming recommendations for attributes as soon as possible.

API Token Management API Now Available
We have introduced a new API Token Management API that enables customers to programmatically regenerate their ThousandEyes user bearer tokens. This enhancement removes the previous limitation of UI-only token management which requires manual intervention. With the API, customers can enhance automation workflows and reduce operational inefficiencies in machine-to-machine integrations.
Highlights:
Both the old and new tokens remain valid for a 14-day grace period, allowing for a seamless transition.
Token regeneration is restricted to the token’s owner.
The existing UI functionality remains unchanged.
For more information, see the API documentation.

ThousandEyes API v6 End-of-Life Reminder
Support for ThousandEyes API v6 ended on May 27, 2025. All API v6 operations will be decommissioned after May 27, 2026. After this date, any integration or workflow that relies on API v6 will stop working.
Why migrate now?
ThousandEyes API v7 is the only version supported by the latest tools and software development kits (SDKs), including the Terraform Provider version 3, ThousandEyes Java SDK, and Python SDK.
API v7 continues to expand with new operations, improved standardization, and enhanced performance.
Migrating early ensures a smoother transition and access to support and resources.
Note: Migration should be done using only the documented API v7 operations. Using undocumented or preview API operations, such as those that appear to work after a v6 to v7 substitution, may result in broken workflows after full deprecation. These operations are not guaranteed to be stable or supported.
To help with migration, we’ve prepared the API v7 Migration Guide.
We strongly recommend completing your migration to API v7 as soon as possible to avoid service disruptions.
Endpoint Agent Client Version 2.17.1
The following enhancements have been made to the Endpoint Agent client:
All Platforms
Resolved an issue from version 2.13.1 that caused the agent to crash when collecting Wi-Fi interface metrics if the operating system did not provide the PHY mode.
Fixed an issue where the diagnostics bundle reports an incorrect system architecture.
Extend support for Cisco ZTA to include scenarios where TIA is used.
Windows
The agent now provides comprehensive Wi-Fi event tracking, irrespective of the device's Location Services status. Previously, no Wi-Fi events were tracked if the location services were disabled.
Resolved an issue where diagnostic bundles might not be created if certain Unicode characters are present in the file path.

UDP Support for Endpoint Agent Dynamic Tests
Dynamic tests running on Endpoint Agent version 2.13.1 or higher now support the User Datagram Protocol (UDP), in addition to TCP and ICMP, to better reflect real-world network traffic. Webex and Microsoft Teams tests now use UDP by default. Each UDP-based dynamic test provides a detailed path trace with UDP traffic. These updates help ensure more accurate and relevant results. We're aware that some UDP tests for Microsoft Teams may report failed path traces, even when end-to-end measurements succeed. We'll provide updates as improvements are made.
