The problem has been discussed in may thread, in the net.
I've read most of them but my HP M.H. is still empty.
New HP ML 350 G8, fresh installed

Jun 25, 2017  Solution: HP Insight Management Agents and WBEM providers do not co-exist; one will override the other. If you have Windows 2008 R2, 2012 upwards, go with.

HP System Management Homepage v7.1.2.3 (after uninstalled and reinstalled the new one - v7.2.0.14)
SNMP service running, to be more conservative I've created a readonly community (public) and a write/read community (private). Authorized hosts: localhost - 127.0.0.1 and the true server's IP
No trap configured (I've tried also that but with no luck).
I've tried to reboot all services involved (smnp then all HP services)
I think that the problem may be in the management homepage itsef, I can't change data source, in the the older one it was possible..

No firewall running, windows server 2008 r2
