NAME


fmd - fault manager daemon

SYNOPSIS


/usr/lib/fm/fmd/fmd [-V] [-f file] [-o opt=val] [-R dir]


DESCRIPTION


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 identifes 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.

1
An error occurred which prevented the fault manager from
initializing, such as failure to open the telemetry transport.
