wmi (Source)

When To Use

Use wmi for Windows system/hardware/application monitoring via WMI classes.

This is one of the highest-usage source types in community connectors.

Syntax

sources:
  logicalDisks:
    type: wmi
    namespace: root\CIMv2
    query: SELECT DeviceID,FreeSpace,Size FROM Win32_LogicalDisk WHERE DriveType = 3
    computes:
    - type: duplicateColumn
      column: 3

Properties

Property Required Default Description
type Yes None wmi.
query Yes None WMI query string.
namespace No Provider default WMI namespace (root\CIMv2, root\Microsoft\Windows\Storage, …).
executeForEachEntryOf No None Fan-out query execution context.
computes No [] Post-processing pipeline.
forceSerialization No false Serialize execution via a per-connector, per-host lock (see the Sources overview). Default false.
  • Keep namespaces explicit for readability and compatibility.
  • Select stable key columns (__PATH, IDs) when later joins are required.
  • Filter and normalize early with computes before mapping.
  • Use tableJoin with keyType: Wbem when joining path-like keys.

Common Mistakes

  • Overusing SELECT *.
  • Joining on display names instead of technical identifiers.
  • Dropping identity columns too early in the pipeline.
