nova-scheduler - Server for the OpenStack Compute scheduler
service.
nova-scheduler [<options>...]
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.
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-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.
- --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.
