1) Create a script/command that monitors something on your system and output the result to stdout.
example
script: /usr/local/bin/check_everything.sh
outputs either...
STATUS: OK - everything good
or
STATUS: NOT OK!
2) Create entry in the SNMP config to the monitor script:
# vi /etc/snmp/userDefinedSettings.conf
add a line...
extend everything_status /bin/sh /usr/local/bin/check_everything.sh
3) restart snmpd
from clish, run "set snmp agent off" then run "set snmp agent on"
4) test it
