fmd - fault manager daemon
/usr/lib/fm/fmd/fmd [-V] [-f file] [-o opt=val] [-R dir]
fmd is a daemon that runs in the background on each system. fmd
receives telemetry information relating to problems detected by the system
software, diagnoses these problems, 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. The message directs
administrators to a knowledge article on http://illumos.org/msg/, which
explains more about the problem impact and appropriate responses.
Each problem diagnosed by the fault manager is assigned a
Universal Unique Identifier (UUID). The UUID uniquely
identifies this particular problem across any set of systems. The
fmdump(1M) utility can be used to view the list of problems diagnosed
by the fault manager, along with their UUIDs and knowledge article
message identifiers. The fmadm(1M) utility can be used to view the
resources on the system believed to be faulty. The fmstat(1M) utility
can be used to report statistics kept by the fault manager. The fault
manager is started automatically when the operating system boots, so it is
not necessary to use the fmd command directly.
The following options are supported
Read the specified configuration file prior to
searching for any of the default fault manager configuration files.
Set the specified fault manager option to the specified
value. Fault manager options are currently a Private interface; see
for information about Private interfaces.
Use the specified root directory for all pathnames
evaluated by the fault manager, instead of the default root (/).

The following exit values are returned:
An error occurred which prevented the fault manager from
initializing, such as failure to open the telemetry transport.
Invalid command-line options were specified.

The Fault Manager is managed by the service management facility, smf(5),
under the service identifier:
The service's status can be queried using the svcs(1)
command. Administrators should not disable the Fault Manager service.
