So this is non-trivial setup. And it is also dependent on your
motherboard (i.e. it perhaps does not do power off events). But lets
see if I can't help you get going. Beyond what I list here, some
knowledge of IPMI internals will be necessary (chapter 17 and 42 are key
starting points).
As an alternate, you may wish to consider using ipmi-seld for
monitoring. It may be easier than this process (here's a plug for my
stackoverflow answer:
http://stackoverflow.com/questions/12505676/script-to-monitor-ipmi-sel-in-real-time/12517475#12517475)

I haven't done this in awhile, so hopefully I get all of this right.
First configure an alert destination.
Section Lan_Alert_Destination_0
Alert_Destination_Type PET_Trap
Alert_Acknowledge Yes
Alert_Acknowledge_Timeout 30
Alert_Retries 2
Alert_Gateway Default
Alert_IP_Address 192.168.1.2
Alert_MAC_Address 00:00:00:00:00:00
EndSection
Timeout & retries are whatever you want. Gateway/IP/MAC per your
system.
Then set up an alert string.
Section Alert_String_0
Event_Filter_Number 3
Alert_String_Set 3
Alert_String mystring
EndSection
Then set up a policy.
Section Alert_Policy_1
Policy_Type
Always_Send_To_This_Destination
Policy_Enabled Yes
Policy_Number 1
Destination_Selector 1
Channel_Number 1
# This matches string set above
Alert_String_Set_Selector 3
Event_Specific_Alert_String No
EndSection
On your system "Channel number" could be different for LAN, see bmc-info
to make sure it's the right one.
then setup an event filter for what you want
Section Event_Filter_1
Filter_Type Software_Configurable
Enable_Filter Yes
Event_Filter_Action_Alert Yes
Event_Filter_Action_Power_Off No
Event_Filter_Action_Reset No
Event_Filter_Action_Power_Cycle No
Event_Filter_Action_Oem No
Event_Filter_Action_Diagnostic_Interrupt No
Event_Filter_Action_Group_Control_Operation No
# Match this to policy above
Alert_Policy_Number 1
Group_Control_Selector 0
Event_Severity Critical
Generator_Id_Byte_1 0xFF
Generator_Id_Byte_2 0xFF
# Power_Unit is for power on/off events
Sensor_Type Power_Unit
Sensor_Number 0xFF
# 6F means sensor specific event
Event_Trigger 0x6F
# "power off" is bit 1
Event_Data1_Offset_Mask 0x01
Event_Data1_AND_Mask 0x00
Event_Data1_Compare1 0xFF
Event_Data1_Compare2 0x00
Event_Data2_AND_Mask 0x00
Event_Data2_Compare1 0xFF
Event_Data2_Compare2 0x00
Event_Data3_AND_Mask 0x00
Event_Data3_Compare1 0xFF
Event_Data3_Compare2 0x00
EndSection

No, the BMC sends the alert. the snmpd daemon is used to receive it on
the other side.
ipmi-pet is only used for parsing the results of a SNMP trap (although
you'd probably want to use the wrapper script
https://www.gnu.org/software/freeipmi/petalert.pl).

Yes, the "Event Filters" in ipmi-pef-config --checkout equate to the
"ipmitool pef list".
The details are really IPMI specific. You might have just as much
trouble understanding the ipmitool output (I can't figure it out just
looking at it).
