I would have very little confidence of the 5.1.x line (or 5.2.x line)
sending such active traps reliably.

The DisMan implementation was completely reworked for the 5.3.x
release, to improve this functionality. If you want the agent to
generate traps in response to this sort of configuration, I would
*strongly* recommend that you upgrade to 5.4.1.

If you need to stay with the 5.1.x line, then you would do better
working with a separate process to monitor the load and generate
traps appropriately.
A simple shell script could work reasonably well. Something
like:

while true
do
load=`uptime | awk '{print $10}' `
if [ $uptime -gt 1.0 ]
then
snmptrap monitorhost ....
fi
sleep 60
done


That's a bit too simplistic, of course. But you get the idea.


If you want the snmpd agent to handle this, then upgrade.
