# Notification Originator
#
# Send SNMP notification using the following options:
#
# * SNMPv3
# * with user 'usr-md5-none', MD5 auth, no priv
# * send INFORM notification
# * in behalf of contextEngineId = SnmpEngineId, contextName 'my-context'
# * over IPv4/UDP
# * with TRAP ID 'warmStart' specified as a string OID
#
# Sending SNMPv3 Notification in behalf of non-default ContextName
# requires having a collection of Managed Objects registered under
# the ContextName being used.
