The WMI Formatted active monitor retrieves a specific value from WMI enabled devices. Windows Management Instrumentation (WMI) is a Microsoft Windows standard for retrieving information from computer systems running Windows. Monitored metrics include systems resources (like CPU, disk and memory utilization) as well as specific process performance counters (like MS Exchange Mailbox and Transport server). Most Microsoft server and desktop operating systems and applications have built-in WMI support.

While similar to the WMI active monitor that uses raw data, the WMI Formatted active monitor uses calculated counter data.

In some cases using the raw counters instead of the WMI Formatted counters will cause WMI Monitors to respond with the error "Failed to load WMI Performance counter: Error=invalid class"

   • Name. Enter a unique name for the active monitor. This name displays in the Active Monitor Library.
   • Description. Enter additional information about the monitor. This description displays next to the monitor in the Active Monitor Library.
5. Click browse (...) to select a performance counter and instance for the monitor.
   • Check type. Select the type of check you want the WhatsUp Gold WMI monitor to make on the performance counter selected above.
     • Constant Value. Monitors the performance counter/instance for a specific value. If the value changes, the monitor triggers a device state change.
     • Range of Values. Monitors the performance counter/instance to make sure the returned value falls within a range of values. If the value falls outside of the range, the monitor triggers a device state change.
     • Rate of Change. Monitors the performance counter/instance to make sure the change in value matches the rate you enter in the check values section. If the rate changes, the monitor triggers a device state change.
   • Constant Value. The value for the designated check type.
   • Rate of Change. The state of the device when the check value is met.
