Monitoring Changes in Registry Keys

Hello,

I have an interesting request I am currently working on.

I need to monitor the number of rows on a SQL table. If that value increases, signal an alert.

So far, I have a script that runs and counts the rows, and stores this value to the local machine as a RegistryKey.

Moving forward, this is where I need some help, logic and/or implementation.. How can I get SCOM to read that RegKey value, and then send a notification/alert of what the value is at the time of reading?

Thanks everyone!
