Every optional collector of the mixin now has alerts, generated only with that collector enabled in _config.collectors: clock source, disk drive status, page file usage, license status, scheduled task results, pending updates, Hyper-V WMI and replication health, failover cluster nodes, resources, groups and shared volumes, Storage Spaces pool and virtual disk health, DHCP scope exhaustion and DNS zone transfer failures. The alerts of the pagefile, diskdrive and license collectors join the memory, disk and system groups; the other collectors get a group of their own. New knobs: taskSelector, sharedVolumeSelector, pagefileUsageThreshold, dhcpScopeFreeWarningThreshold, dhcpScopeFreeCriticalThreshold and updatePendingDuration. The test configuration enables every optional collector and tests/optional.test.yaml covers the new alerts. Signed-off-by: Jan-Otto Kröpke <mail@jkroepke.de>

title: WindowsLicenseNotGenuine
|
|
---
|
|
|
|
## Meaning
|
|
|
|
Windows reports a license status other than `genuine` for one hour. The alert
|
|
carries the status in its `state` label and needs the `license` collector. The
|
|
status comes from the Software Licensing service and changes when an
|
|
activation expires, a KMS host is unreachable for more than the grace period,
|
|
the hardware changed, or the key was blocked. `offline` means the genuine
|
|
validation could not reach Microsoft; on hosts without internet access that
|
|
is the permanent state, so turn the alert off there with
|
|
`alerts+: { WindowsLicenseNotGenuine: false }` or scope it with the exporter
|
|
selector.
|
|
|
|
## Impact
|
|
|
|
An unlicensed Windows shows activation notices, may limit personalization and,
|
|
on some editions, restarts on a schedule. A Windows Server that leaves its
|
|
activation grace period is out of compliance.
|
|
|
|
## Diagnosis
|
|
|
|
1. The `state` label of the alert names the status; `windows_license_status`
|
|
shows all states of the host.
|
|
2. On the host, read the license details:
|
|
|
|
```powershell
|
|
slmgr.vbs /dlv
|
|
slmgr.vbs /xpr
|
|
Get-CimInstance SoftwareLicensingProduct -Filter "PartialProductKey IS NOT NULL" | Select-Object Name, LicenseStatus, GracePeriodRemaining
|
|
```
|
|
|
|
3. For KMS clients, check that the KMS host resolves through the `_vlmcs._tcp`
|
|
DNS record and answers on TCP port 1688. For Active Directory based
|
|
activation, check the activation object in the forest. For MAK or retail
|
|
keys, check whether the activation count is exhausted.
|
|
|
|
## Mitigation
|
|
|
|
Restore reachability to the KMS host or the activation object, then run
|
|
`slmgr.vbs /ato`. Install the correct key with `slmgr.vbs /ipk <key>` if the
|
|
key was wrong, or reactivate after a hardware change. Confirm the status
|
|
returns to `genuine`.
