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

-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(5) 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.

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.

The Fault Manager is managed by the service management facility, smf(5), under the service identifier:


 svc:/system/fmd:default

The service's status can be queried using the svcs(1) command. Administrators should not disable the Fault Manager service.
