 FMSTAT 8 "Aug 26, 2019"
 NAME
fmstat - report fault management module statistics
 SYNOPSIS
fmstat [-astTz] [-d u | d ] [-m module] [interval [count]]


 DESCRIPTION
The fmstat utility can be used by administrators and service personnel to
report statistics associated with the Fault Manager, fmd(8) and
its associated set of modules. The Fault Manager runs in the background on each
system. It 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.

You can use fmstat to view statistics for diagnosis engines and agents
that are currently participating in fault management. The documentation for
fmd(8), fmadm(8), and fmdump(8) describes more about tools
to observe fault management activities.

If the -m option is present or the -t option is present,
fmstat reports any statistics kept by the specified fault management
module. The module list can be obtained using fmadm config.

If the -m option is not present, fmstat reports the following
statistics for each of its client modules:
module

The name of the fault management module, as reported by fmadm config.


ev_recv

The number of telemetry events received by the module.


ev_acpt

The number of events accepted by the module as relevant to a diagnosis.


wait

The average number of telemetry events waiting to be examined by the module.


svc_t

The average service time for telemetry events received by the module, in
milliseconds.


%w

The percentage of time that there were telemetry events waiting to be examined
by the module.


%b

The percentage of time that the module was busy processing telemetry events.


open

The number of active cases (open problem investigations) owned by the module.


solve

The total number of cases solved by this module since it was loaded.


memsz

The amount of dynamic memory currently allocated by this module.


bufsz

The amount of persistent buffer space currently allocated by this module.


The fmstat utility requires the user to possess the PRIV_SYS_ADMIN
privilege. See privileges(7).
 OPTIONS
The following options are supported:
-a

Print all statistics for a module, including those kept on its behalf by
fmd. If the -a option is not present, only those statistics kept by
the module are reported. If the -a option is used without the -m
module, a set of global statistics associated with fmd are
displayed.


-d u | d

Display a time stamp.
Specify u for a printed representation of the internal representation of
time. See time(2). Specify d for standard date format. See
date(1).


-m module

Print a report on the statistics associated with the specified fault management
module, instead of the default statistics report. Modules can publish an
arbitrary set of statistics to help Sun service the fault management software
itself. The module statistics constitute a Private interface. See
attributes(7) for information on Sun's rules for Private interfaces.
Scripts should not be written that depend upon the values of fault management
module statistics as they can change without notice.


-s

Print a report on Soft Error Rate Discrimination (SERD) engines associated with
the module instead of the default module statistics report. A SERD engine is a
construct used by fault management software to determine if a statistical
threshold measured as N events in some time T has been exceeded.
The -s option can only be used in combination with the -m option.


-t

Print a report on the statistics associated with each fault management event
transport. Each fault management module can provide the implementation of one
or more event transports.


-T

Print a table of the authority information associated with each fault
management event transport. If the -m option is present, only transports
associated with the specified module are displayed.


-z

Omit statistics with a zero value from the report associated with the specified
fault management module. The -z option can only be used in combination
with the -m option.


 OPERANDS
The following operands are supported:
count

Print only count reports, and then exit.


interval

Print a new report every interval seconds.


If no interval and no count are specified, a single report is
printed and fmstat exits. If an interval is specified but no
count is specified, fmstat prints reports every interval
seconds indefinitely until the command is interrupted.
 EXIT STATUS
The following exit values are returned:
0

Successful completion.


1

A fatal error occurred. A fatal error could be the failure to communicate with
fmd(8). It could also be that insufficient privileges were available to
perform the requested operation.


2

Invalid command-line options were specified.


 ATTRIBUTES
See attributes(7) for descriptions of the following attributes:


ATTRIBUTE TYPE ATTRIBUTE VALUE
Interface Stability See below.


The command-line options are Evolving. The human-readable default report is
Unstable. The human-readable module report is Private.
