Description of configuration options for [DEFAULT] in object-server.conf
Configuration option = Default value Description
backlog = 4096 Maximum number of allowed pending TCP connections
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
client_timeout = 60 Timeout to read one chunk from a client external services
conn_timeout = 0.5 Connection timeout to external services
devices = /srv/node Parent directory of where devices are mounted
disable_fallocate = false Disable "fast fail" fallocate checks if the underlying filesystem does not support it.
disk_chunk_size = 65536 Size of chunks to read/write to disk
eventlet_debug = false If true, turn on debug logging for eventlet
expiring_objects_account_name = expiring_objects No help text available for this option.
expiring_objects_container_divisor = 86400 No help text available for this option.
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`.
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_facility = LOG_LOCAL0 Syslog log facility
log_level = INFO Logging level
log_max_line_length = 0 Caps the length of log lines to the value given; no limit if set to 0, the default.
log_name = swift Label used when logging
log_statsd_default_sample_rate = 1.0 Defines the probability of sending a sample for any given event or timing measurement.
log_statsd_host = localhost If not set, the StatsD feature is disabled.
log_statsd_metric_prefix = Value will be prepended to every metric sent to the StatsD server.
log_statsd_port = 8125 Port value for the StatsD server.
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_udp_host = If not set, the UDP receiver for syslog is disabled.
log_udp_port = 514 Port value for UDP receiver, if enabled.
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.
mount_check = true Whether or not check if the devices are mounted to prevent accidentally writing to the root device
network_chunk_size = 65536 Size of chunks to read/write over the network
node_timeout = 3 Request timeout to external services
swift_dir = /etc/swift Swift configuration directory
user = swift User to run as
workers = auto a much higher value, one can reduce the impact of slow file system operations in one request from negatively impacting other requests.
