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
