Oliver Kieselbach 7c27518dbb feat(vuln): emit VulnerabilityCacheWarmupCompleted customEvent per cold start
Trace-level warmup logs are dropped by default App Insights sampling, so
ops cannot reliably tell whether the MSRC / KEV cache hydration ran
cleanly on a given cold start. Add a sampling-bypass customEvent
(host.json already excludes "Event" from sampling) emitted once per
warmup run.

Captured properties let ops verify runtime health at a glance:
- msrcEntries / kevEntries — how many entries each cache holds after hydrate
- msrcBlobHit / kevBlobHit — derived from entries > 0; false on first deploy
  before any sync has written the blob, true on every subsequent cold start
- msrcLastRefresh / kevLastRefresh — ISO timestamp from the persisted snapshot
- durationMs — total warmup wall time (parallel Task.WhenAll, typically <100ms)
- errorType / errorMessage — populated only if Task.WhenAll threw

Query:
  customEvents
  | where name == 'VulnerabilityCacheWarmupCompleted'
  | project timestamp, customDimensions
  | order by timestamp desc

Autopilot Monitor

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.

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

Architecture

For detailed information about the system architecture, components, and data flow, see Architecture Documentation.
