Release Notes: September 2021

2021-09-01

Changes to Webapp Session Timeout Duration

In the coming weeks, ThousandEyes will change the default session timeout duration from indefinite to 30 minutes. This change will patch a security vulnerability, as well as better align the timeout duration with industry best practices.
As part of this change, the keep_session_alive_on_auto-update permission will be automatically removed from all default built-in roles. This change could affect customers that continuously display ThousandEyes dashboards (for example, in Network Operations Centers).
If you would like to preserve the keep_session_alive_on_auto-update permission for certain users within your organization, we recommend that you create a custom role with this permission and assign users in the appropriate account group to that role.
For more information on creating custom roles, see Managing Roles.

Changes to Billing Page

We will be temporarily disabling the Billing History view in the Usage and Billing section of the web app while we work on a fix to correct some inaccuracies we've noticed with the data presented there.
While we implement this fix, please reach out to your account representative for data on billing and usage for previous periods.

Updated Dashboards and Reports Caching Mechanism

The caching mechanism for dashboards and reports has been updated to improve end-to-end performance. As part of this change, the cache time has been increased from 5 minutes to 10 minutes. This will result in a delay in updated dashboards and reports when you change the ownership of a test to a different account or organization ID.
For example, if the test ownership moves from Account Group A to Account Group B, this change will only be reflected in a customer's dashboard or report when the cache is updated, meaning there is a maximum potential delay of 10 minutes.

2021-09-01 Bug Fixes

  • Previously, searching the Endpoint Agent Agent Settings filter list for values of any of four specific metrics (User, VPN Gateway Address, VPN Client Address, or VPN Client Network) would not work correctly. This has been resolved.
  • A display issue caused new Endpoint Agents to only display the username, but not the agent name for the host device. Both agent name and the username are now displayed again on the Agent Settings page.
  • Previously, some alerts were not clearing, even after the associated alert rule was disabled or deleted. This was due to a configuration propagation issue that has since been corrected.
  • An issue was fixed where report and dashboard widgets were incorrectly inheriting names of previously named widgets on save.

Changes to the te-browserbot Package's Dependencies on RHEL 7 and Oracle Linux 7

In the coming months, as part of an architectural change to BrowserBot, ThousandEyes will add te-podman as a dependency of the te-browserbot package. This new package depends on some packages available in the Red Hat Enterprise Linux 7 Server - Extras and Oracle Linux Addons repositories for RHEL 7 and Oracle Linux 7, respectively.
Users with existing agents running on RHEL 7 should enable the rhel-7-server-extras-rpms repository. Users with existing agents running on Oracle Linux 7 should enable the ol7_addons repository. Otherwise, BrowserBot will not be able to upgrade to this forthcoming version.
On RHEL 7, you can enable this required repository by executing subscription-manager repos --enable=rhel-7-server-extras-rpms. On Oracle Linux 7, execute yum-config-manager -q -y --enable ol7_addons.

New Cloud Agents

New Cloud Agents have been added to the following locations:
  • Madrid, Spain (IPv6)
  • Mumbai, India (JIO)
  • Mumbai, India (JIO) (IPv6)
For a full list of Cloud Agents, see ThousandEyes Cloud Agent Locations.

2021-09-14 Bug Fixes

  • An issue was found in the Stacked Area graph widget for reports and dashboards when displaying a Page Load metric. The calculation for the metric was adding DOM load time to the page load time, which is incorrect, as DOM load time is a sub-component of page load time. This has now been resolved and the correct value is displayed.

2021-09-16

Metric Calculation Improvements for Reports and Dashboards

We have improved the way we calculate the Availability metric for Device data in reports and dashboards. Availability is now calculated based on the number of interfaces that are up and running divided by the number of interfaces that the admin set as up. This is a slight change to the previous calculation, which also included in rare instances interfaces that were up and running even if they were set as down by the admin.
Additionally, customers can now query Device Availability by median, max, min, Nth percentile and standard deviation.

Changes to Update Email Limit

Effective immediately, ThousandEyes will be making an update to our profile logic so that requests to update the email address of a provisioned user will only be accepted a maximum of once per hour. Once that limit is reached, subsequent requests to update email will then be blocked by the system until the hour period has passed. This change will patch a security vulnerability. We do not anticipate this change to affect customer account access outside of the above limitation.

2021-09-29

Endpoint Agent Notifications Update

We have moved Endpoint Agent notifications to our new backend notifier. This results in several changes to notifications, including:

Webhooks

  • Added ruleName, violationCount, ruleAID, and type as new fields.
  • Changed browserSessionAlert to alert.
  • Added a permalink, but maintained the soon to be deprecated link field.
  • Most strings are now in human readable format.
These changes should not require customers to update their webhooks. However, you should review your downstream systems to ensure there is no impact.

Email

  • Changed from Browser Session (Application) to Browser Session Application.
  • The order of Start Date and Number of Sites Visited is flipped.
  • Changed from Scope to No. of Agents.

Pager Duty:

  • Added No. of Visited Sites.
  • Changed from AlertID to Alert ID.
  • Removed the dedicated field for ruleExpression and instead have the human readable form in the Alert Rule field.

Slack

  • Removed the dedicated field for ruleExpression and instead have the human readable form in the Alert Rule field.
  • Added Target and Test Names as fields.
  • Changed from Scope to No. of Agents.

New Cloud Agents

New Cloud Agents have been added to the following locations:
  • Glasgow, Scotland (IPv6)
  • Louisville, KY, USA (IPv6)
  • New York, NY (IPv6)
  • New York, NY (Cogent) (IPv6)
For a full list of Cloud Agents, see ThousandEyes Cloud Agent Locations.

2021-09-29 Bug Fixes

  • Previously, if an Endpoint Agent user was connected via a remote desktop, the temporary directory would change. This caused requests for the temporary directory location to fail, as system processes were still using the previously configured location. This has been resolved.
  • Previously, an issue was found where grouping by devices in a report or dashboard widget was not correctly populating individual device names. This has been resolved.
