SCOM newbie here... I've just installed SCOM and deployed to agent to only a few servers. I'm trying to setup monitoring and alerts/emails but I'm getting confused. When I go to Authoring > Management Packs > Monitors, I can see 71 monitors, but when I expand them, there is nothing configured. It's as if the management packs came preinstalled with SCOM 2025, but they're blank.

Do you have to have management packs to create monitors? I found a site where you can download management packs, but I just want to create a monitor for logical disk space for all servers, no matter OS version, and then if any drive reaches 90%, it emails me.

Doesn't seem very straight forward so far, and documentation leads me down these paths where I realize I am missing a configuration/management pack/monitor somewhere because their screenshots have monitors setup, but my environment has nothing.

Any help is appreciated!
