NAME

       nova-scheduler - Server for the OpenStack Compute scheduler service.

SYNOPSIS

          nova-scheduler [<options>...]

DESCRIPTION

       nova-scheduler  is  a  server  daemon  that  serves  the Nova Scheduler service, which is responsible for
       picking a compute node to run a given instance on.

OPTIONS

       General options

       --config-dir DIR
              Path to a config directory to pull *.conf files from. This file set is sorted, so as to provide  a
              predictable parse order if individual options are over-ridden. The set is parsed after the file(s)
              specified via previous --config-file, arguments hence over-ridden options in  the  directory  take
              precedence.  This option must be set from the command-line.

       --config-file PATH
              Path  to  a config file to use. Multiple config files can be specified, with values in later files
              taking precedence. Defaults to None. This option must be set from the command-line.

       --debug, -d
              Set the logging level to DEBUG instead of the default INFO level.

       --log-config-append PATH, --log-config PATH, --log_config PATH
              The name of a  logging  configuration  file.  This  file  is  appended  to  any  existing  logging
              configuration files.  For details about logging configuration files, see the Python logging module
              documentation. Note that when logging configuration files are used then all logging  configuration
              is set in the configuration file and other logging configuration options are ignored (for example,
              log-date-format).

       --log-date-format DATE_FORMAT
              Defines the format string for %(asctime)s in log records. Default: None .  This option is  ignored
              if log_config_append is set.

       --log-dir LOG_DIR, --logdir LOG_DIR
              (Optional)  The  base  directory  used  for  relative  log_file  paths.  This option is ignored if
              log_config_append is set.

       --log-file PATH, --logfile PATH
              (Optional) Name of log file to send logging output to.  If no default is set, logging will  go  to
              stderr as defined by use_stderr. This option is ignored if log_config_append is set.

       --nodebug
              The inverse of --debug.

       --nouse-journal
              The inverse of --use-journal.

       --nouse-json
              The inverse of --use-json.

       --nouse-syslog
              The inverse of --use-syslog.

       --nowatch-log-file
              The inverse of --watch-log-file.

       --syslog-log-facility SYSLOG_LOG_FACILITY
              Syslog facility to receive log lines. This option is ignored if log_config_append is set.

       --use-journal
              Enable  journald  for  logging. If running in a systemd environment you may wish to enable journal
              support.  Doing so will use the journal native protocol  which  includes  structured  metadata  in
              addition to log messages.This option is ignored if log_config_append is set.

       --use-json
              Use JSON formatting for logging. This option is ignored if log_config_append is set.

       --use-syslog
              Use  syslog  for  logging. Existing syslog format is DEPRECATED and will be changed later to honor
              RFC5424.  This option is ignored if log_config_append is set.

       --version
              Show program's version number and exit

       --watch-log-file
              Uses logging handler designed to watch file system.  When  log  file  is  moved  or  removed  this
              handler  will  open  a  new  log  file with specified path instantaneously. It makes sense only if
              log_file  option  is  specified  and  Linux  platform  is  used.  This  option   is   ignored   if
              log_config_append is set.

       Debugger options

       --remote_debug-host REMOTE_DEBUG_HOST
              Debug  host  (IP  or  name)  to  connect  to. This command line parameter is used when you want to
              connect to a nova service via a debugger running on a different host. Note that using  the  remote
              debug  option changes how Nova uses the eventlet library to support async IO. This could result in
              failures that do not occur under normal operation. Use at your own risk.

       --remote_debug-port REMOTE_DEBUG_PORT
              Debug port to connect to. This command line parameter allows you to specify the port you  want  to
              use  to  connect  to  a nova service via a debugger running on different host. Note that using the
              remote debug option changes how Nova uses the eventlet library to support  async  IO.  This  could
              result in failures that do not occur under normal operation. Use at your own risk.
