```
public static final String OHM_NAMESPACE
```
    The namespace where Open Hardware Monitor publishes to WMI, OHM_NAMESPACE="ROOT\\OpenHardwareMonitor". This namespace is not built-in to WMI, so if OHM is not running would result in unnecessary log messages.

```
    Gets a Uint64 value from a WmiResult (parsing the String). Note that while the CIM type is unsigned, the return type is signed and the parsing will exclude any return values above Long.MAX_VALUE.
    
    Type Parameters:
    
    T - WMI queries use an Enum to identify the fields to query, and use the enum values as keys to retrieve the results.

    property - The property (column) to fetch
    
    index - The index (row) to fetch

```
    Gets an UINT32 value from a WmiResult. Note that while a UINT32 CIM type is unsigned, the return type is signed and requires further processing by the user if unsigned values are desired.

    property - The property (column) to fetch
    
    index - The index (row) to fetch
    
    Returns:
    
    The stored value if non-null, 0 otherwise
