phase_change/phase_exit/on_event gather triggers (and the phase-scope gates) were driven by the pre-reduce SignalIngress.SignalPosted stream, so any raw signal carrying an EspPhase payload fired them before the decision engine had applied its gates. In session 32312a32 (RealmJoin tenant) a Phase Start rule on FinalizingSetup fired at the raw ESP-exit EspPhaseChanged(FinalizingSetup) signal, 7 minutes before the engine's RealmJoin-gated phase_transition(FinalizingSetup) - and read HKLM\SOFTWARE\RealmJoin\Custom\BIOS before the RealmJoin package that creates it had run (exists=false). GatherRuleExecutorHost now subscribes to the new TimelineEventStream: EventTimelineEmitter publishes every emitted event's (eventType, phase) post-reduce, so phase triggers fire exactly when the UI timeline shows the phase, and on_event sees engine-emitted event types (enrollment_complete, phase_transition, realmjoin_resolved, ...) that never existed on the raw signal stream - restoring V1 semantics and the documented "On Event with enrollment_complete" pattern. Raw-signal consumers with OS-state semantics (DeviceInfoHost, UserEspKeepAwakeHost, ProvisioningPackageHost) stay on the raw feed deliberately. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
AutopilotMonitor
Advanced monitoring and troubleshooting solution for Windows Autopilot deployments. Gain full visibility into every enrollment session with a detailed event timeline, fleet health dashboards, and session reporting. Define custom analysis rules to automatically detect issues and gather rules to collect targeted evidence. Retrieve diagnostics packages on demand, configure agent settings like auto-reboot behavior and automatic timezone adjustment — all managed centrally from the web dashboard.
Availability
Autopilot Monitor is publicly available — the Community plan is free. Sign in with your work account at autopilotmonitor.com; new organizations complete a short activation step after first sign-in.
Overview
Autopilot Monitor provides real-time tracking, intelligent diagnostics, and automated troubleshooting for Windows Autopilot enrollment processes. It consists of:
- Bootstrap Script — PowerShell script deployed via Intune that starts monitoring early in the enrollment process
- Monitoring Agent — Lightweight .NET application that collects telemetry and evidence during enrollment
- Backend API — Azure Functions-based ingestion and processing pipeline
- Web Dashboard — Next.js application for real-time monitoring and fleet analytics
