FMSTAT(1M) Maintenance Commands FMSTAT(1M)


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 Solaris Fault Manager, fmd(1M) and
its associated set of modules. The Fault Manager runs in the background
on each Solaris 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(1M), fmadm(1M), and fmdump(1M) 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 posses the SYS_CONFIG privilege.
Refer to the for more information about how to configure Solaris
privileges.

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(5) 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(1M). It could also be that insufficient
privileges were available to perform the requested operation.


2
Invalid command-line options were specified.


ATTRIBUTES


See attributes(5) 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.
