WAN Insights: Enhanced Visibility for Cloud OnRamp Applications

WAN Insights now offers extended support for vManage Cloud OnRamp (CoR) applications. For all WAN Insights users who are using vManage's CoR feature to route traffic to SaaS applications in the cloud via Direct Internet Access (DIA), this enhancement adds a seamless way to onboard CoR applications into WAN Insights using WAN Insights' existing workflow for adding new applications.

To onboard CoR applications into WAN Insights, first onboard your CoR applications in vManage. Within 24 hours, your application will show up in WAN Insights, ready for onboarding using the Add new application workflow as described in Adding Business-Critical Applications to WAN Insights.

With the addition of CoR applications, you can now monitor the health and performance of your DIA paths using WAN Insights' comprehensive quality score, troubleshoot reported issues more quickly, and review path recommendations to improve path quality and user experience.

Updates to Test Templates

Improve Error and Warning Messages for Duplicate Test Names

Error and warning messages for resolving duplicate test names are now clearer.

2023-09-27

Update to the Snapshot Expiration Notification

We have made an update to the existing notification regarding snapshot expiration. The update includes the addition of "Dashboard" as a prefix to the notification. This change helps to reduce any confusion that might arise from other snapshot expiration notifications, such as those for the Endpoint Agent. With the new update, the notification will be more specific and will read as follows: 6 Dashboard Snapshots Expiring within 30 days.

ServiceNow, PagerDuty and Slack Integration Updates

ServiceNow, PagerDuty, and Slack integrations are now exclusively managed on the Integrations page. Users can no longer create or manage these integrations from the alert rule Notifications tab. However, the option to assign integrations to alert rules is still available on the alert rule Notifications tab.

Cloud Agents Added

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

  • New Orleans, LA, USA (IPv4)

  • New Orleans, LA, USA (IPv6)

  • Winnipeg, Canada (Telus)

  • Winnipeg, Canada, (Telus) (IPv6)

2023-09-27 Bug Fixes

  • Resolved an issue that was showing erroneous HTML tags in the popup message for certificate errors detected by the Endpoint Agent browser session tests.

  • Fixed an issue that was incorrectly adding the "Copy" suffix to Endpoint Agent labels while generating dashboards using this data.

  • Fixed an issue in the time series widget of the dashboards where the drill-down URL was missing the agentId, resulting in redirecting to the incorrect view.
