ThousandEyes Integration with Browser Real User Monitoring	You can integrate ThousandEyes with Browser Real User Monitoring. This integration combines application data from AppDynamics and internet network metrics from ThousandEyes to provide full-stack observability. When you add the ThousandEyes widget in the browser application dashboard, you can: View ThousandEyes network metrics (packet loss, latency, and jitter) and network health in the context of browser applications. Analyze the impact of network performance on application performance Analyze how latency, packet loss, and jitter affect end-user response time and application errors Identify whether the network is the cause of application issues: Network issue affecting a specific geographic location Network issue affecting a specific domain Network issue (latency) causing higher end-user response time Network issue (packet loss) causing errors in applications Network issue (jitter) causing inconsistent user experience Narrow down the network issue to a specific domain and a specific location Forward the ThousandEyes test with the network issue to the NetworkOps team for further troubleshooting Troubleshoot the network issue by navigating to the ThousandEyes dashboard See ThousandEyes Integration with Browser Real User Monitoring. To activate the integration, you need an active license of any of the following EUM licenses and an active subscription to ThousandEyes Network and Application Synthetics: Real User Monitoring (SaaS) - Peak Edition Browser Real User Monitoring (SaaS) - Peak Edition For the license entitlements, see License Entitlements and Restrictions. If you have an existing ThousandEyes integration, add and save the ThousandEyes credentials again for this integration to work.	23.4.0	May 2, 2023
Accounts	Users can obtain one identity across Controller tenants and Accounts by completing an email address verification process. Once verified, users can use the same identity across multiple tenants and accounts, making it easier to manage their access and permissions. See AppDynamics Global Identity Migration Experience - FAQ.	23.4.0	April 10, 2023
Alert and Respond	When you create or update a health rule for the type User Experience Browser Apps, you can now select the following metrics for the entities Pages or Virtual Pages: `Visually Complete Time (ms)` `Visually Complete Time 50th percentile (ms)` `Visually Complete Time 90th percentile (ms)` `Visually Complete Time 95th percentile (ms)` `Visually Complete Time 99th percentile (ms)` These metrics are selected to evaluate the critical or warning criteria. You can now monitor the user experience by tracking how much time does it takes for all visual elements within the first screen (above-the-fold content) to load in an end user’s browser and get alerted for any issues. See Create and Configure Conditions.	23.4.0	April 10, 2023
Alert and Respond	You can now configure a policy to detect a failed HTTP request action. An HTTP request action fails due to various reasons such as incorrect payload, server unreachable, or gateway timeout. In such scenarios, the policy triggers and you can set up an automatic notification through email or message. You can take corrective action accordingly. See Configure Policies.	23.4.0	April 10, 2023

Licensing	When using Infrastructure-based Licenses (IBL), you have the option to enable license rules that help you conserve license consumption for a Cluster Agent when the system is unable to detect its vCPU information. In such cases, the Cluster Agent without vCPU information will be rejected and won't be registered. This helps you avoid consuming a license for the agent. See Machine and Cluster Agent License Prioritization.	23.4.0	April 10, 2023
Dash Studio	A new list view is introduced that includes Last Viewed and Views in Last 7 Days columns and minor enhancements. The health widget now supports the `within` function for business transactions.	23.4.0	April 26, 2023

Known Issues

23.4 Agent Known Issues

Agent

Summary

Database Agent

In the Metric Browser, the keys of one Database Collector get displayed under other Database Collectors.

For example, keys of Database Collector 1 can appear under Database Collector 2, even if the keys are not part of the Database Collector 2 query output.

This issue occurs when you create a custom metric that runs on multiple databases and returns multiple key-value pairs. In such scenarios, only the keys get duplicated, not the metric values.

Java Agent

Sometimes the Java Agent does not discover the correct container ID while running within the cgroup v2 container because there are no official methods of getting the container ID within the cgroup v2 container. However, Java Agent utilizes a common knowledge algorithm that can discover correct IDs in some cases.

23.4 Controller Known Issues

Key	Issue Summary
SYNTH-9374	The pagination function does not work in the Show TE Tests pop-up.
SYNTH-9324	An error message is displayed when you click Sync with ThousandEyes if there are a large number of ThousandEyes tests. However, the sync operation continues successfully in the background. Action: No user action is required.
SYNTH-9306	ThousandEyes network metrics from existing ThousandEyes tests are not ingested to newly added browser applications after the initial sync with ThousandEyes.
SYNTH-9415	If you are an existing customer of ThousandEyes alerts integration, updating the ThousandEyes credentials fails if you are on Controller version <23.4.0. Action: Update the ThousandEyes credentials after the UI Cloud 23.5.0 release or upgrade to Controller version >=23.4.0.
