# The SNMP traps for the NetApp filer can be found in

# NFS automounted mounted on server.
# Example: the SNMP id for cpuBusyTimePerCent is
# snmp.1.3.6.1.4.1.789.1.2.1.3.0
# and retrival of this value is done by
# snmpget -v 1 -c public netappfiler 1.3.6.1.4.1.789.1.2.1.3.0
#
# Requires snmpget and assumes public community.
