NAME

       account-server.conf - configuration file for the OpenStack Swift account server

SYNOPSIS

       account-server.conf

DESCRIPTION

       This  is  the  configuration  file used by the account server and other account background
       services, such as; replicator, auditor and reaper.

       The configuration file follows the python-pastedeploy syntax. The  file  is  divided  into
       sections,  which  are  enclosed  by  square  brackets. Each section will contain a certain
       number of key/value parameters which are described later.

       Any line that begins with a '#' symbol is ignored.

       You  can  find  more  information  about  python-pastedeploy   configuration   format   at
       http://pythonpaste.org/deploy/#config-format

GLOBAL SECTION

       This is indicated by section named [DEFAULT]. Below are the parameters that are acceptable
       within this section.

       bind_ip
              IP address the account server should bind to. The default  is  0.0.0.0  which  will
              make it bind to all available addresses.

       bind_port
              TCP port the account server should bind to. The default is 6202.

       bind_timeout
              Timeout to bind socket. The default is 30.

       backlog
              TCP  backlog.   Maximum number of allowed pending connections. The default value is
              4096.

       workers
              The number of pre-forked processes that will accept  connections.   Zero  means  no
              fork.   The  default  is auto which will make the server try to match the number of
              effective cpu cores if python multiprocessing  is  available  (included  with  most
              python distributions >= 2.6) or fallback to one.  It's worth noting that individual
              workers will use many eventlet co-routines to service multiple concurrent requests.

       max_clients
              Maximum number of clients one worker can process simultaneously (it  will  actually
              accept(2)  N  + 1). Setting this to one (1) will only handle one request at a time,
              without accepting another request concurrently.  The default is 1024.

       ionice_class
              Modify  I/O  scheduling  class  of  server processes. I/O niceness class values are
              IOPRIO_CLASS_RT (realtime),  IOPRIO_CLASS_BE  (best-effort)  and  IOPRIO_CLASS_IDLE
              (idle).   The  default  does  not  modify  class  and  priority.   Work  only  with
              ionice_priority.

       ionice_priority
              Modify I/O scheduling priority of server processes.  I/O  niceness  priority  is  a
              number  which goes from 0 to 7. The higher the value, the lower the I/O priority of
              the process. Work only with ionice_class.  Ignored if IOPRIO_CLASS_IDLE is set.

PIPELINE SECTION

       This is indicated by section name [pipeline:main].  Below  are  the  parameters  that  are
       acceptable within this section.

       pipeline
              It  is  used when you need apply a number of filters. It is a list of filters ended
              by an application. The normal pipeline is "healthcheck recon account-server".

APP SECTION

       This is indicated by section name [app:account-server]. Below are the parameters that  are
       acceptable within this section.

       use    Entry  point  for paste.deploy for the account server. This is the reference to the
              installed python egg.  This is normally egg:swift#account.

       set log_name
              Label used when logging. The default is account-server.

       set log_facility
              Syslog log facility. The default is LOG_LOCAL0.

              Configure parameter for creating specific server.  To handle all  verbs,  including
              replication  verbs,  do  not specify "replication_server" (this is the default). To
              only handle replication, set to a true value (e.g. "true" or "1"). To  handle  only
              non-replication  verbs,  set  to  "false".  Unless  you have a separate replication
              network, you should not specify any value for "replication_server". The default  is
              empty.

       nice_priority
              Modify  scheduling  priority  of  server  processes. Niceness values range from -20
              (most favorable to the process) to  19  (least  favorable  to  the  process).   The
              default does not modify priority.

       ionice_class
              Modify  I/O  scheduling  class  of  server processes. I/O niceness class values are
              IOPRIO_CLASS_RT (realtime),  IOPRIO_CLASS_BE  (best-effort)  and  IOPRIO_CLASS_IDLE
              (idle).   The  default  does  not  modify  class  and  priority.   Work  only  with
              ionice_priority.

       ionice_priority
              Modify I/O scheduling priority of server processes.  I/O  niceness  priority  is  a
              number  which goes from 0 to 7. The higher the value, the lower the I/O priority of
              the process. Work only with ionice_class.  Ignored if IOPRIO_CLASS_IDLE is set.

FILTER SECTION

       Any section that has its name prefixed by "filter:" indicates a filter  section.   Filters
       are  used  to  specify configuration parameters for specific swift middlewares.  Below are
       the filters available and respective acceptable parameters.

       [filter:healthcheck]

          use    Entry point for  paste.deploy  for  the  healthcheck  middleware.  This  is  the
                 reference to the installed python egg.  This is normally egg:swift#healthcheck.

          disable_path
                 An optional filesystem path which, if present, will cause the healthcheck URL to
                 return "503 Service Unavailable" with a body of "DISABLED BY FILE".

       [filter:recon]

          use    Entry point for paste.deploy for the recon middleware. This is the reference  to
                 the installed python egg.  This is normally egg:swift#recon.

          recon_cache_path
                 The  recon_cache_path simply sets the directory where stats for a few items will
                 be stored.  Depending on the method of deployment you may need  to  create  this
                 directory  manually  and  ensure  that  swift  has  read/write.  The  default is
                 /var/cache/swift.

       [filter:xprofile]

          use    Entry point for paste.deploy for the xprofile middleware. This is the  reference
                 to the installed python egg.  This is normally egg:swift#xprofile.

          profile_module
                 This  option  enable  you  to  switch profilers which should inherit from python
                 standard  profiler.  Currently  the   supported   value   can   be   'cProfile',
                 'eventlet.green.profile' etc.

          log_filename_prefix
                 This prefix will be used to combine process ID and timestamp to name the profile
                 data file.  Make sure the executing user has permission to write into this  path
                 (missing  path segments will be created, if necessary).  If you enable profiling
                 in more than one type of daemon, you must override it with an unique value like,
                 the default is /var/log/swift/profile/account.profile.

          dump_interval
                 The profile data will be dumped to local disk based on above naming rule in this
                 interval. The default is 5.0.

          dump_timestamp
                 Be careful, this option will enable profiler to dump data  into  the  file  with
                 time  stamp  which  means there will be lots of files piled up in the directory.
                 The default is false

          path   This is the path of  the  URL  to  access  the  mini  web  UI.  The  default  is
                 __profile__.

          flush_at_shutdown
                 Clear the data when the wsgi server shutdown. The default is false.

          unwind Unwind the iterator of applications. Default is false.

                 set.

       [account-reaper]

          log_name
                 Label used when logging. The default is account-reaper.

                 Normally,  the  reaper  begins deleting account information for deleted accounts
                 immediately; you can set this to  delay  its  work  however.  The  value  is  in
                 seconds.  The  default  is  0.   The sum of this value and the container-updater
                 interval should be less than the account-replicator  reclaim_age.  This  ensures
                 that  once  the  account-reaper has deleted a container there is sufficient time
                 for the container-updater to report to the account  before  the  account  DB  is
                 removed.

          reap_warn_after
                 If  the  account  fails  to  be be reaped due to a persistent error, the account
                 reaper will log a message such as:
                     Account <name> has not been reaped since <date> You can search logs for this
                 message if space is not being reclaimed after you delete account(s).  Default is
                 2592000 seconds (30 days).  This  is  in  addition  to  any  time  requested  by
                 delay_reaping.

          nice_priority
                 Modify  scheduling  priority of server processes. Niceness values range from -20
                 (most favorable to the process) to 19 (least favorable  to  the  process).   The
                 default does not modify priority.

          ionice_class
                 Modify  I/O  scheduling class of server processes. I/O niceness class values are
                 IOPRIO_CLASS_RT (realtime), IOPRIO_CLASS_BE (best-effort) and  IOPRIO_CLASS_IDLE
                 (idle).   The  default  does  not  modify  class  and  priority.  Work only with
                 ionice_priority.

          ionice_priority
                 Modify I/O scheduling priority of server processes. I/O niceness priority  is  a
                 number  which goes from 0 to 7. The higher the value, the lower the I/O priority
                 of the process. Work only with ionice_class.  Ignored  if  IOPRIO_CLASS_IDLE  is
                 set.
