Description of configuration options for [DEFAULT] in object-server.conf-sample

Configuration option = Default value	Description
bind_ip = 0.0.0.0	IP Address for server to bind to
bind_port = 6000	Port for server to bind to
bind_timeout = 30	Seconds to attempt bind before giving up
backlog = 4096	Maximum number of allowed pending TCP connections
user = swift	User to run as
swift_dir = /etc/swift	Swift configuration directory
devices = /srv/node	Parent directory of where devices are mounted
mount_check = true	Whether or not check if the devices are mounted to prevent accidentally writing to the root device
disable_fallocate = false	Disable "fast fail" fallocate checks if the underlying filesystem does not support it.
expiring_objects_container_divisor = 86400	No help text available for this option
workers = auto	a much higher value, one can reduce the impact of slow file system operations in one request from negatively impacting other requests.
max_clients = 1024	Maximum number of clients one worker can process simultaneously Lowering the number of clients handled per worker, and raising the number of workers can lessen the impact that a CPU intensive, or blocking, request can have on other requests served by the same worker. If the maximum number of clients is set to one, then a given worker will not perform another call while processing, allowing other workers a chance to process it.
log_name = swift	Label used when logging
log_facility = LOG_LOCAL0	Syslog log facility
log_level = INFO	Logging level
log_address = /dev/log	Location where syslog sends the logs to
log_custom_handlers =	Comma-separated list of functions to call to setup custom log handlers.
log_udp_host =	If not set, the UDB receiver for syslog is disabled.
log_udp_port = 514	Port value for UDB receiver, if enabled.
log_statsd_host = localhost	If not set, the StatsD feature is disabled.
log_statsd_port = 8125	Port value for the StatsD server.
log_statsd_default_sample_rate = 1.0	Defines the probability of sending a sample for any given event or timing measurement.
log_statsd_sample_rate_factor = 1.0	Not recommended to set this to a value less than 1.0, if frequency of logging is too high, tune the log_statsd_default_sample_rate instead.
log_statsd_metric_prefix =	Value will be prepended to every metric sent to the StatsD server.
eventlet_debug = false	If true, turn on debug logging for eventlet
fallocate_reserve = 0	You can set fallocate_reserve to the number of bytes you'd like fallocate to reserve, whether there is space for the given file size or not. This is useful for systems that behave badly when they completely run out of space; you can make the services pretend they're out of space early. server. For most cases, this should be `egg:swift#object`.
