This is monitoring a single instance, rather than a MIB object.
Try adding the option -I (capital i)

If you've got a suitable "disk" configuration (either an individual entry,
or "includeAllDisks"), which will set the dskErrorFlag object when the
disk gets too full, then you can monitor this object instead - either
on an individual basis, or via "defaultMonitors"

This directive would monitor the unix 1, 5 and 15 minute load averages,
and set the relevant error flag if the load goes over 0.7
You could use the same value for all three, but it would be more usual
to have higher threshold values for the shorter time periods.
Something like
"load 2.0 1.0 0.7"
would trigger an alert if the one-minute load average was >2,
if the 5-minute load average was >1 or if the 15-minute load average was >0.7
That would allow short-term peaks of "medium" activity, while still detecting
longer-term heavy-ish use, or short-term major overload.
