SNMP Monitoring
TODO:finish this section. The majority of this section will get moved
to the external CySNIIP docs and this will be stuff specific to the
imapd.
Cyrus uses an auxillary process called "tugowar", so named because
there's a push-pull model. Various components of the Cyrus mail system
push data to tugowar, and tugowar listens for SNMP queries (remote
clients pull the data from tugowar).
