DEFAULT¶

debug¶

Type: boolean
Default: false
Mutable: This option can be changed without restarting.

If set to true, the logging level will be set to DEBUG instead of the default INFO level.

log_config_append¶

Type: string
Default: <None>
Mutable: This option can be changed without restarting.

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).

Deprecated Variations¶
Group	Name
DEFAULT	log-config
DEFAULT	log_config

log_date_format¶

Type: string
Default: %Y-%m-%d %H:%M:%S

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¶
