subsystem. If it is equal to SYSLOG_UP, then the
subsystem is currently filtering and forwarding
syslog messages. If it is SYSLOG_DOWN then it is
not forwarding messages because of several
possiblities:
1) No hosts are configured for the subsystem,
2) No hosts are enabled
3) Hosts are enabled but have no respective
filters enabled
