I would like the ability to check NCM settings to ensure real time change detetion is enabled. I simple solution would be to have the application write a syslog message if the setting is changed. A syslog rule could be configured to catch this change.
you could setup a Windows Script Monitor that checks the following key in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\SolarWinds.net\Configuration Manager\Settings\Real-Time Notifications
It can be true or false.
It seems that it exists few WMI Class for the registry, I am not sure if they can be used to monitor a specific key remotely.
Look for this on google to start your script: remote reg query
