sorry for delay reply, Dave, cause i have to do more basic reading, including
manual and RFCs.

Yes, i have read compeletely the part of directives in snmpd.conf(5) manual
related with ucdavis MIB
such as load,file and so on, and know how and which some entries added to the
realted ucdavis MIB table.
yes, using monitor directive DO CAN monitor cpu idle time and memory
usage(included with "defaultMonitors yes").
thanks.

yeah, i have walked through the ucdavis MIB definition, all the OIDs are
read-only except prErrFix(so we can set it manual thourh snmpset and
trigger a trap send), so i can not set the threshold dynamically by this way.

If i configure a trigger test in the DisMan Event table manually, such as
boolean test, i have to add entry into mteTriggerTable and
mteTriggerBooleanTable
respectively. these OIDs all are read-write, so i can set something dynamically
by
this way, right?
i think it's a little complex cause that there are some dependency along with
some tables. i have to be very careful.

sorry, english is not my native language, i really understand what you mean.

maybe i have to do more digging at this aspect, including RFCs and code, and
do more practise, so i can get you.
thank you for your reply Dave!
