## Target

Typical platform: **[Microsoft Windows](platforms/microsoft-windows.html)**

Operating system: **Microsoft Windows**

## Prerequisites

Leverages: **WMI**

Technology and protocols: **WMI/WinRM**

## Examples

### CLI

```batch
metricshub HOSTNAME -t win -c +WBEMGenLUN --wmi -u USER
```

### metricshub.yaml

```yaml
resourceGroups:
  <RESOURCE_GROUP>:
    resources:
      <HOSTNAME-ID>:
        attributes:
          host.name: <HOSTNAME> # Change with actual host name
          host.type: win
        connectors: [ +WBEMGenLUN ] # Optional, to load only this connector
        protocols:
          wmi:
            username: <USERNAME> # Change with actual credentials
            password: <PASSWORD> # Encrypted using metricshub-encrypt

## Connector Activation Criteria

The **WMI - LUN** connector will be automatically activated, and its status will be reported as OK if all the below criteria are met:

- Operating System is **Microsoft Windows**
- The Windows service **WINMGMT** is running
- The **WMI query** below to the managed host succeeds: 
  
    - Namespace: `root\wmi`
    - WQL Query: `SELECT NumberDrives,DriveInfo.Name FROM MPIO_DISK_INFO`
    - Result contains: `^[1-9][0-9]*;[^;].*;$` (regex)
