Per SolarWinds Support, the WMI Monitor does not allow a statistical value and a message to be queried via WMI at the same time, instead entirely relying on scripting through Windows Script Monitor or PowerShell just to pull one text string.
The SQL Server User Experience Monitor allows for two values to be queried and populated - statistic and message - and this have been a life saver in some instances where the text is far more useful than the stat. To be able to record a stat and a message from WQL would allow users to manipulate any data out of WMI that they may need.
While it may not be the most efficient method, for a single line item per server it can be a lifesaver (for instance gathering Standard or Enterprise OS from thousands of servers using select countrycode, caption from Win32_OperatingSystem, acknowledging only the caption text being the desired data).
