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(8) 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(8) 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(8) utility can be used to view the resources on the system believed to be
faulty. The
fmstat(8) 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.
OPTIONS
The following options are supported
-f file Read the specified configuration
file prior to searching
for any of the default fault manager configuration files.
-o opt=value Set the specified fault manager option to the specified
value. Fault manager options are currently a Private
interface; see
attributes(7) for information about
Private interfaces.
-R dir Use the specified root directory for all pathnames
evaluated by the fault manager, instead of the default
root (
/).
-V Print the fault manager's version to stdout and exit.
EXIT STATUS
The following exit values are returned:
0 Successful completion
1 An error occurred which prevented the fault manager from
initializing, such as failure to open the telemetry transport.
2 Invalid command-line options were specified.
FILES
