Configuration Options¶
oslo.log uses oslo.config to define and manage configuration options to allow the deployer to control how an application’s logs are handled.
DEFAULT¶
debug
Type: boolean Default: false
If set to true, the logging level will be set to DEBUG instead of the default INFO level.
verbose
Type: boolean Default: true
If set to false, the logging level will be set to WARNING instead of the default INFO level.
log_config_append
Type: string Default: <None>
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, logging_context_format_string).
Deprecated Variations¶ Group Name DEFAULT log_config
log_date_format
Type: string Default: %Y-%m-%d %H:%M:%S
Defines the format string for %%(asctime)s in log records. Default: %(default)s . This option is ignored if log_config_append is set.
log_file
Type: string Default: <None>
(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.
Deprecated Variations¶ Group Name DEFAULT logfile
log_dir
Type: string Default: <None>
(Optional) The base directory used for relative log_file paths. This option is ignored if log_config_append is set.
Deprecated Variations¶ Group Name DEFAULT logdir
watch_log_file
Type: boolean Default: false
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.
use_syslog
Type: boolean Default: false
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.
syslog_log_facility
Type: string Default: LOG_USER
Syslog facility to receive log lines. This option is ignored if log_config_append is set.
use_stderr
Type: boolean Default: true
Log output to standard error. This option is ignored if log_config_append is set.
logging_context_format_string
Type: string Default: %(asctime)s.%(msecs)03d %(process)d %(levelname)s %(name)s [%(request_id)s %(user_identity)s] %(instance)s%(message)s
Format string to use for log messages with context.
logging_default_format_string
Type: string Default: %(asctime)s.%(msecs)03d %(process)d %(levelname)s %(name)s [-] %(instance)s%(message)s
Format string to use for log messages when context is undefined.
logging_debug_format_suffix
Type: string Default: %(funcName)s %(pathname)s:%(lineno)d
Additional data to append to log message when logging level for the message is DEBUG.
logging_exception_prefix
Type: string Default: %(asctime)s.%(msecs)03d %(process)d ERROR %(name)s %(instance)s
Prefix each line of exception output with this format.
logging_user_identity_format
Type: string Default: %(user)s %(tenant)s %(domain)s %(user_domain)s %(project_domain)s
Defines the format string for %(user_identity)s that is used in logging_context_format_string.
default_log_levels
Type: list Default: amqp=WARN,amqplib=WARN,boto=WARN,qpid=WARN,sqlalchemy=WARN,suds=INFO,oslo.messaging=INFO,iso8601=WARN,requests.packages.urllib3.connectionpool=WARN,urllib3.connectionpool=WARN,websocket=WARN,requests.packages.urllib3.util.retry=WARN,urllib3.util.retry=WARN,keystonemiddleware=WARN,routes.middleware=WARN,stevedore=WARN,taskflow=WARN,keystoneauth=WARN,oslo.cache=INFO,dogpile.core.dogpile=INFO
List of package logging levels in logger=LEVEL pairs. This option is ignored if log_config_append is set.
publish_errors
Type: boolean Default: false
Enables or disables publication of error events.
instance_format
