net-snmp help

[Neil Watson]

Try as I might cannot get net-snmp to send traps for any high loads or
disk space shortages. Started snmpd and then load the CPU for more than
15 minutes. I also, filled the /home partition to 100%. In both cases
tcpdump showed no snmp traffic other than a trap send when the agent was
started. Both load and disk traps were not generated. Why?
