You can't generalize like that. I have many alerts/incidents like this in my EM environment: Tablespace [SYSTEM] is [90 percent ] full

If it doesn't work at all for you then maybe you only have a warning or a critical threshold set on the metric? 12c requires you set BOTH warning and critical thresholds. Otherwise the metric is completely disabled and you get no incidents created. So let's say you want an alert when a tablespace reaches 90% full and that's it, then set warning to 90 and critical to 101. Then only warning level alerts are generated and you just set up your incident/notification rules accordingly.

I had almost the same issues as you.

I have 100+ databases monitoring at the environment.

I upgrade to 12c from 11g. The BP1 version is a nightware. Then, I upgraded to BP2.

Some of the issues are solved in the BP2 version. But others not.

For example, the tablespace full alert is not working at BP2, neither on 10g or 11g instances.
