Hello again,
It seems that the remote SNMP can't read the power status. I looked at a DL 380 server as it has it's own power and when i look at the Health Status i also see a Power Status green. But then agai nthat's a Windows 2008 server with WBEM agent.
I even checked there is no WBEM agent for your platform. Perhaps you can get your event from your ILO then.(that's also an option) Do you know how ? If not let me know.
