dmi collector

The dmi collector exposes Desktop Management Interface (DMI) / SMBIOS system information, compatible with node_exporter's dmi collector.

Metric name prefix	dmi
Data source	GetSystemFirmwareTable (SMBIOS)
Enabled by default?	No

Flags

None

Metrics

Name	Description	Type	Labels
windows_dmi_info	A metric with a constant '1' value labeled by SMBIOS Type 1 (System Information) fields.	gauge	product_name, product_serial, product_uuid, product_version, system_vendor

On VMs the labels reflect the hypervisor-assigned identity; on physical hosts they reflect the hardware SMBIOS data. If SMBIOS data cannot be read (e.g. in some container environments), the collector will fail to build.

Example metric

# HELP windows_dmi_info A metric with a constant '1' value labeled by product_name, product_serial, product_uuid, product_version, system_vendor from SMBIOS Type 1 (System Information).
# TYPE windows_dmi_info gauge
windows_dmi_info{product_name="Standard PC (Q35 + ICH9, 2009)",product_serial="Not Specified",product_uuid="12345678-1234-1234-1234-123456789abc",product_version="pc-q35-9.2",system_vendor="QEMU"} 1

Useful queries

Cross-exporter compatibility

The label names match node_exporter's node_dmi_info metric, so dashboards and alerts work across Linux and Windows guests:

# Works for both Linux and Windows guests
{__name__=~"node_dmi_info|windows_dmi_info"}

Correlate with libvirt_exporter

With prometheus-libvirt-exporter, the domain UUID is exposed on libvirt_domain_info_meta{uuid="..."}. This UUID matches the SMBIOS UUID passed to the guest by QEMU/KVM.

Add the product_uuid label to any guest metric:

windows_memory_physical_free_bytes
  * on(job, instance) group_left(product_uuid)
windows_dmi_info

Join a host-side libvirt metric with the guest-identified UUID (full guest→host chain):

libvirt_domain_info_memory_usage_bytes
  * on(job, instance, domain) group_left(uuid)
libvirt_domain_info_meta
  * on(uuid) group_left()
label_replace(windows_dmi_info, "uuid", "$1", "product_uuid", "(.+)")

Alerting examples

This collector does not yet have alerting examples, we would appreciate your help adding them!
