Diagnostic Themes
Every signal a data feed or a health topic produces is filed under one theme, the kind of problem it belongs to. Start from a theme when you know the symptom and not yet the source.
| Theme | What you will find | Signals |
|---|---|---|
| Crashes and hangs | A service, process or the OS restarted, hung or crashed unexpectedly. | 59 |
| Storage and filesystem | A disk, volume or share is unreadable, full, slow or unprotected. | 50 |
| Backup and VSS | A backup job or the shadow-copy service behind it failed or degraded. | 11 |
| Patching and servicing | Windows Update or the servicing stack failed to scan, download or install a patch. | 44 |
| Security and identity | An account, credential, permission or audit setting changed in a way worth checking. | 138 |
| Network | A network adapter, link or remote-access path failed or degraded. | 30 |
| Performance and capacity | CPU, memory, disk or queue pressure crossed a level that slows workloads. | 21 |
| Configuration drift | A host setting, inventory value or scheduled task changed outside the expected configuration. | 52 |
