I don't think this is a Solarwinds issue, but I'm curious if anyone's ever created a WMI performance counter monitor that returns no value. I'm using WMI Explorer to find what I'm looking for, and it seems to work for some things, but not what I'm looking for. APM also returns no information, but these counters work perfectly using Perfmon, so I'm a little confused. How is it that these performance counters can work so well with Perfmon, but when accessed using WMI I can only get the row labels and not the counter information?
Here's an example of my Query
select AverageMailSizeKB from Win32_PerfRawData_TmImssMTA_IMSS
The error back from APM is "Invalid WMI Query No results were returned by WQL query"
