Endpoint Agent Views 2.0 General Availability
After a very positive limited preview, we are pleased to announce the general availability of Endpoint Agent Views 2.0, an upgrade designed to streamline troubleshooting and enhance the user experience. As we stated in our previous announcement, with the general availability of the new version, the previous one is deprecated.
Key Features and Enhancements of Agent View 2.0:
Segmented Visualization: Quickly identify where the problem lies by segmenting the end-to-end path based on its owner, helping technicians locate, escalate, and resolve issues quickly.
Segment Scores: Provides a simplified view of network health, allowing users to assess the impact of issues at a glance.
Per-Process Information: Offers detailed insights into CPU and memory usage by specific applications and processes, enabling targeted action to resolve performance issues.
In addition, we are excited to announce the following enhancements in our general availability release, inspired by valuable feedback from our limited preview users:
Enhanced Internet Segment: The Internet segment now clearly identifies when the root cause of an issue can be related to a problem with an Internet node or link, making troubleshooting more efficient.
Peer Information per Application: Users can now quickly determine if an issue with an application is isolated to a specific agent or if it indicates a broader outage affecting multiple users. This feature helps in discerning whether the problem is with the application itself or external factors.
Guided Troubleshooting: For issues impacting multiple segments of a specific application, our new guided troubleshooting feature assists users in pinpointing the most likely segment causing the problem, streamlining the diagnostic process.
See Endpoint Agent Views 2.0 for more information.
Microsoft Teams Data Integration General Availability

For more information about the integration and how it can improve your Microsoft Teams meeting experience, please see this article
Permanent Fix for Endpoint Agent Wi-Fi Reporting for macOS 14.6 and Above
As previously announced, we have implemented a solution for WiFi reporting for macOS and above. The endpoint agent version 1.229.2 and above, will request location permissions from macOS users, allowing it to retrieve location information such as SSID and BSSID for the ThousandEyes Endpoint Agent. Users must opt-in to location services being enabled within their operating system to enable us to report this information to the ThousandEyes user interface.
Once users grant location permissions, the following issues will be resolved:
SSID and BSSID values will be displayed in reports.
SSID information will be populated in tables.
The Wireless Info and Connection segments will show SSID/BSSID information.
Labels based on SSID/BSSID will function properly, and test assignments relying on these labels will also work as intended.
Data tagging: Data points will be tagged correctly, and filtering functionality will be restored.
What is not supported:
For users who choose not to opt in, reports will display a fixed value in the format
Unknown SSID - Agent Name / Unknown BSSID - Agent Name.If the user has opted in but is logged out from their machine, reports will display a fixed value in the format
Unknown SSID / Unknown BSSID.Apple states that user interaction is necessary to enable Location Services and to agree to share location data with each application. Therefore, no system-level or MDM tool can enable this functionality on a large scale.
See Endpoint Installation for more information.
Endpoint Agent Client Version 1.229.2
The following enhancements have been made to the Endpoint Agent client:
All Platforms
Resolved a bug that occasionally caused the message "the server's response was invalid" to appear for some TCP tests targeting certain targets.
Previously, Endpoint Agent path visualizations displayed an IPv4 address as an agent's source address for a network test, even for network tests toward IPv6 targets. Now, the correct source address used for the network test is displayed.
Previously, some local user accounts linked to a specific agent were registered multiple times, causing the same username to appear repeatedly in the ThousandEyes UI. Although this issue was addressed in a previous release, the outdated client registrations still displayed duplicate usernames in the UI. This has been resolved, and the UI no longer shows duplicate usernames.
Windows
The Endpoint Agent now reports the WiFi Transmission Rate (TxRate) even if the location services are turned off on Windows 11 24H2 and above.
Platform Renaming and Information Architecture Changes Reminder
As previously announced, the ThousandEyes platform will undergo several changes to the left navigation menu and UI components after February 18th, 2025. While these changes will not impact our APIs or developer experience, they will affect the ThousandEyes platform user interface. These changes include, but are not limited to:
Renaming the Cloud & Enterprise Agents menu item to Network & App Synthetics.
Renaming the Endpoint Agents menu item to Endpoint Experience.
Renaming Snapshots to Public Snapshots.
Renaming Saved Events to Private Snapshots.
Adding a Routing landing page to the left-hand navigation for BGP functionality.
Adding an Event Detection landing page to the left-hand navigation.
Streamlining platform settings under a new Manage page in the left-hand navigation including Sharing and Account Settings
Renaming the Cloud & Enterprise Agents data type used in the platform to Network & App Synthetics.
Renaming the Endpoint Agents data type used in the platform to Endpoint Experience.
The names of individual agent types, such as Cloud Agents, Enterprise Agents, and Endpoint Agents, will remain unchanged.
The change scope will include renaming, re-ordering, and re-architecting the menu items in the left-hand navigation panel; updating page URLs, renaming some page elements and updating technical documentation accordingly. The goal is to provide more intuitive and solution-based naming to create an easy-to-use workflow. Learn more about the updated UI by watching the introduction video.

VerifySSL Added to API Test Type
The API tests type now supports both client certificate authentication and disable SSL verification, similar to all other web test types.
Adding client certificates for your API test be found under Test Settings, on the TLS section of the Advanced Settings tab.
Disabling SSL verification for each API call can be configured in the Authentication tab of the API Step Builder.
Changes to Sticky Agent Global Alert Rule Definition
We have made an update to our sticky trigger alert logic to better match expected behavior in a specific edge case. Previously, if multiple agents were included in the alert rule, the sticky trigger logic required that the exact same agents triggered during the exact same rounds to trigger the alert.
For example, if the alert rule read "The same 2 agents 2 out of 3 rounds", and Agent A tripped the threshold in Round 1 and Round 2, and Agent B tripped the threshold in Round 2 and Round 3, the alert wouldn't trigger, since the agents didn't trigger in the exact same round. The above alert would only trigger if both Agent A and Agent B tripped the threshold in the same exact two of three rounds.
The new logic would trigger an alert in the above scenario, as the same two agents did trip the threshold in 2 of 3 rounds, albeit in slightly different rounds.
2025-02-18
ThousandEyes Enterprise Agents on Cisco NFV Infrastructure Software (NFVIS)
ThousandEyes now supports the installation of Enterprise Agents on top of Cisco devices supporting NFVIS, as a form of virtual network function (VNF) within a container. This includes support for the C8200 uCPE and C8300 uCPE as well as UCS rack servers which support NFVIS. We recommend installation via SD-WAN Manager, but support standalone installations of NFVIS as well.
For more information, see NFVIS.
SD-WAN Manager ThousandEyes Workflow
Beginning with SD-WAN Manager 20.16, we have a new pathway for deploying ThousandEyes Enterprise Agents and test templates from within SD-WAN Manager. This new workflow simplifies the process of onboarding new sites and locations into your ThousandEyes environment by providing an easy to follow seven step workflow directly in SD-WAN Manager, that starts by linking your ThousandEyes account using OAuth2.
For more information, see Installing Enterprise Agents on Cisco Routers using the SD-WAN Manager ThousandEyes Workflow.
Updates to Enterprise Agent Token Hashing
Beginning on August 29th, 2024, we implemented an updated method of hashing the agent token used by the Enterprise Agent to authenticate to the ThousandEyes platform, to improve the security of the communications. All running and online agents have already been updated, and no action is required for this improvement.
For agents that were registered prior to August 29th, 2024, and have been offline since, you will need to reinstall or register them once we deprecate the old hashing method on March 12th, 2025, as these agent tokens will be invalidated.
2025-02-19
Stream ThousandEyes Telemetry Data to Splunk from the UI
You can now create an integration to stream ThousandEyes telemetry data to Splunk Enterperise and Splunk Cloud from the ThousandEyes Platform. For more information, see Configuring ThousandEyes for Splunk Cloud or Enterprise using the UI.
