AWS appstream2: New WorkSpaces Applications session connection and disconnect metrics

Service: appstream2 · 2026-10-24 · Documentation medium

File: appstream2/latest/developerguide/instance-session-metrics-single-session-multi-session.md · Type: logging

Summary

Documents five new instance/session CloudWatch metrics: SessionDisconnects, SessionLaunchLatency, ConnectionAttempts, ConnectionSuccesses, and ConnectionFailures, with dimensions and statistics.

Security assessment

The added metrics (notably ConnectionAttempts/ConnectionFailures and SessionDisconnects) provide per-user, per-session observability that can support monitoring and anomaly detection, but they are operational metrics rather than a security control or vulnerability fix.

Evidence

+`ConnectionFailures` |  The number of failed connections to the instance. |  [Fleet] [UserId] [FleetName, InstanceId, SessionId] [FleetName, InstanceId, SessionId, UserId] | Sum | Count
