Updates to Test Templates

API-Only Support for the SIP Server Test Type

You can now deploy a template containing a SIP server test via the API. Overriding SIP server test settings when deploying via API is also supported.

• Fixed an issue where tooltips were showing when their corresponding elements were not hovered.

Endpoint Agent Client Version 1.182.1

Improvements have been made to the Endpoint Agent client on the following platforms:

All Platforms

• Tests using the auto-detect probe mode will now re-check every three hours to ensure that the best mode is being used. We will continue to re-check after any network change event.

• TCP tests are now able to attempt to use SACK probe mode even when remote hosts advertise that they will not accept SACK responses.

• Our TCP testing engine is now more efficient and can handle more edge cases, such as reporting partial paths when receiving a premature RST packet.

• You can now query the status of an agent via your command-line interface. Invoking the agent binary (te-agent) with the --status flag returns the last time the agent checked in, the version of the product, and the agent status.

Windows

• When the Windows Background Intelligent Transfer Service (BITS) fails to download the updater multiple times, the updater now falls back to directly downloading the updated packages.

• Endpoint Agents will no longer create a machine.json file under the ProgramData folder, for added security. The properties contained in this file are now obtained via the system registry.

• The Cisco AnyConnect integration now detects connection/disconnection status faster and more reliably by querying the AnyConnect COM object directly.

Bug Fixes

• All Platforms: A case of an unusually high latency prompted us to improve our TCP test engine to be more robust against clock skew.

Introducing Real-Time Alert Suppression Windows

Customers familiar with creating alert suppression windows (ASWs) now have the ability to apply an ASW to an alert in real time, after it has triggered. You can now remove alerts from a busy alert list using real-time ASWs to:

• Reduce noise.

• Better prioritize alerts.

• Account for late-breaking or unscheduled maintenance.

• Account for a known outage.

Real-time ASWs remove alerts from the Active Alerts list, and display them instead on the Alert History screen for the duration of the window. Set a window for anywhere from an hour to seven days, or create a custom window.

A new column in the Active Alerts screen labeled Action allows you to remove and suppress an alert directly from the screen, while you can find alerts that are currently suppressed on the Alerts History screen with the label Suppressed.

To differentiate real-time ASWs from those that are scheduled ahead of an event, we have renamed the latter scheduled ASWs. The function of scheduled ASWs has not changed.

In addition, two new fields will be added to the "Active alerts" and "Alert details" v6 API endpoint response payloads, providing metadata on suppressed alerts:

• The "Suppressed" field indicates whether an alert is currently suppressed by a real-time alert suppression window (datatype: Integer).

• The "Metadata.version" field tracks the number of times an alert has entered the TRIGGER state. This is useful when an alert reactivates post alert suppression window if the underlying conditions persist (datatype: Integer).

For more information about how to configure a real-time ASW, see Configuring Real-Time ASWs. The rollout of real-time ASWs has begun gradually and is expected to be completed by Friday, December 15, 2023.

Updates to Test Templates

Add a “Created by ThousandEyes” Certification for Test Templates

A new certification has been added called "Created by ThousandEyes" for test templates that are created internally by ThousandEyes for common use cases that can also serve as a quick way to get started with the platform. The existing certifications, ThousandEyes Certified and Partner Certified remain unchanged. The key difference between ThousandEyes Certified and Created by ThousandEyes is that ThousandEyes Certified are associated with a "Best Practices Guide" in order to address more complex use cases. For more information about certification types, see Test Templates: Certifications.

Upcoming Workflow and Name Changes for Endpoint Agent

At the end of January 2024, a new test configuration workflow that utilizes test templates will be introduced. This is a workflow-only change and it won't affect tests that are already in place. As part of the new workflow we will also introduce two naming convention changes, noted below:

1. Automated Session Tests (ASTs) will be renamed to "Dynamic Tests".

2. Browser Sessions will be renamed to "Real User Tests".

Combined the Create Dashboard and Duplicate Dashboard Side Modals

When using "Duplicate Dashboard," the context of the original dashboard will now appear. Customers enrolled in the dashboard filters limited preview (see Dashboard Filters) will also be able to select default dashboard filters for the new dashboard. Contact your account team to get early access to dashboard filters.

Default Internet Insights Network and Application Outages Alert Rules

All new paid or trial Internet Insights customers will no longer have default alerts automatically generated. Users will now need to set up alerts to align with their environment and applications in order to be notified of outages.

Existing customers will still have access to the alerts that were automatically generated for them.

You can find more information in the document covering setting up Internet Insights alerts.

New Cloud Agents

New Cloud Agents have been added in the locations listed below. For a full list of Cloud Agents, see ThousandEyes Cloud Agent Locations.
