Well, there are two programs, snmptrapd and snmpd on nexenta/solaris.
I assume that if you configure/run snmptrapd, that it will listen for
traps.  Not exactly sure what that would accomplish for us.  Normally
in a production environment I would not want a leopard also configured
to be a SNMP trap host client.  Would I?  Yes, I'm very proud of myself
for using the proper SNMP terminology.  One day when I'm older I'll
actually know what it means.  Oops, I'm already older.  Sigh.

SNMP_Message1.JPG shows the alert as it is received (bold highlighting)
and SNMP_Message2.JPG just shows the complete set of messages (upper
six) that come through when an AC cord is unplugged and then re-plugged.
Note that the IP address 10.11.1.220 is the one setup in the BMC BIOS
settings (mostly for IPMI use), so there is not any response to an SNMP
query.  I think that means that if there is not any active monitoring
when the event messages are sent, then they are lost.  I was unable to
figure out how to get the BMC to send the alert to a destination that
the Nexenta/OpenSolaris system noticed.  There may be an OpenSolaris
service which could receive an SNMP alert, but when I tried setting
up the appliances IP address as the destination address for alerts,
I could not see any reflection in the /var/adm/messages file or NMS log
file that would indicate the system saw the SNMP alert.
