DESCRIPTION
This tool is part of the samba(7) suite.
smbstatus is a very simple program to list the current Samba
connections.
OPTIONS
-P|--profile
If samba has been compiled with the profiling option, print only
the contents of the profiling shared memory area.
-R|--profile-rates
If samba has been compiled with the profiling option, print the
contents of the profiling shared memory area and the call rates.
-b|--brief
gives brief output.
-v|--verbose
gives verbose output.
-L|--locks
causes smbstatus to only list locks.
-B|--byterange
causes smbstatus to include byte range locks.
-p|--processes
print a list of smbd(8) processes and exit. Useful for scripting.
-S|--shares
causes smbstatus to only list shares.
-N|--notify
causes smbstatus to display registered file notifications
-f|--fast
causes smbstatus to not check if the status data is valid by
checking if the processes that the status data refer to all still
exist. This speeds up execution on busy systems and clusters but
might display stale data of processes that died without cleaning up
properly.
-u|--user=<username>
selects information relevant to username only.
-n|--numeric
causes smbstatus to display numeric UIDs and GIDs instead of
resolving them to names.
-j|--json
Output more detailed information in JSON format instead of human
readable. The output has the following format:

-?|--help
Print a summary of command line options.
--usage
Display brief usage message.
-d|--debuglevel=DEBUGLEVEL
level is an integer from 0 to 10. The default value if this
parameter is not specified is 1 for client applications.
The higher this value, the more detail will be logged to the log
files about the activities of the server. At level 0, only critical
errors and serious warnings will be logged. Level 1 is a reasonable
level for day-to-day running - it generates a small amount of
information about operations carried out.
Levels above 1 will generate considerable amounts of log data, and
should only be used when investigating a problem. Levels above 3
are designed for use only by developers and generate HUGE amounts
of log data, most of which is extremely cryptic.
Note that specifying this parameter here will override the log
level parameter in the /etc/samba/smb.conf file.
--debug-stdout
This will redirect debug output to STDOUT. By default all clients
are logging to STDERR.
--configfile=<configuration file>
The file specified contains the configuration details required by
the client. The information in this file can be general for client
and server or only provide client specific like options such as
client smb encrypt. See /etc/samba/smb.conf for more information.
The default configuration file name is determined at compile time.
--option=<name>=<value>
Set the smb.conf(5) option "<name>" to value "<value>" from the
command line. This overrides compiled-in defaults and options read
from the configuration file. If a name or a value includes a space,
wrap whole --option=name=value into quotes.
-l|--log-basename=logdirectory
Base directory name for log/debug files. The extension ".progname"
will be appended (e.g. log.smbclient, log.smbd, etc...). The log
file is never removed by the client.
--leak-report
Enable talloc leak reporting on exit.
--leak-report-full
Enable full talloc leak reporting on exit.
-V|--version
Prints the program version number.
