Reset monitors all at once with a script

I have searched the internet for scripts to reset them each all at once. I have found a couple of scripts and ran them in the SCOM Shell and they say that that are resetting the alerts but in actuality, they don't.
The scripts I used were found at these 2 sites:

Does anyone know of a script that actually works for this purpose.
