- report fault management module statistics
fmstat [-astTz] [-d u | d ] [-m module] [interval [count]]
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:
The name of the fault management module, as reported by fmadm config.
The number of telemetry events received by the module.
The number of events accepted by the module as relevant to a diagnosis.
The average number of telemetry events waiting to be examined by the module.
The average service time for telemetry events received by the module, in milliseconds.
The percentage of time that there were telemetry events waiting to be examined by the module.
The percentage of time that the module was busy processing telemetry events.
The number of active cases (open problem investigations) owned by the module.
The total number of cases solved by this module since it was loaded.
The amount of dynamic memory currently allocated by this module.
The amount of persistent buffer space currently allocated by this module.
The fmstat utility requires the user to posses the SYS_ADMIN privilege. Refer to the Oracle Solaris Administration: Security Services for more information about how to configure Solaris privileges.
The following options are supported:
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.
Display a time stamp.
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.
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.
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.
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.
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.
The following operands are supported:
Print only count reports, and then exit.
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.
The following exit values are returned:
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.
Invalid command-line options were specified.
See attributes(5) for descriptions of the following attributes:
The command-line options are Committed. The human-readable default report is Uncommitted. The human-readable module report is Private.
