System Health not working on 6.48.3

I’ve got a RB750Gr3.
System Health isn’t working.
It wasn’t working at all on 6.48.2 so I upgraded to 6.48.3. Now I only see this from terminal:
/system health>> print
voltage: 24V
temperature: 44C

I see the same in Winbox 3.28. Only voltage and temperature.

Any help would be appreciated.

and what other fields you expect to see?

from 6.46.8

      voltage: 24.3V
  temperature: 31C

Ooops. I what I was looking for was System Resources! Not System Health.

Thanks rextended.
