man fmd has the following blurb. So make sure you have the fmd running. ps -ef|grep -i fmd should confirm. Also post your /etc/syslog.conf, could be an issue with your syslog configuration.
Quote:
fmd is a daemon that runs in the background on each Solaris
system. fmd receives telemetry information relating to prob-
lems detected by the system software, diagnoses these prob-
lems, and initiates proactive self-healing activities such
as disabling faulty components. When appropriate, the fault
manager also sends a message to the syslogd(1M) service to
notify an administrator that a problem has been detected.
