       traffic_server - Traffic Server

DESCRIPTION

OPTIONS

       -a, --accepts_thread

       -b, --accept_till_done

       -B TAGS, --action_tags TAGS

       --bind_stdout FILE

       The file to which the stdout stream for Traffic Server will be bound.

       --bind_stderr FILE

       The file to which the stderr stream for Traffic Server will be bound.

       -C 'CMD [ARGS]', --command 'CMD [ARGS]'

       Run  a  Traffic  Server maintenance command. These commands perform various administrative
       actions or queries against Traffic Server. Note that  some  commands  (such  as  help  and
       verify_global_plugin)  take  an argument. To invoke the command and its argument, surround
       the  CMD  and  its  argument  in  quotes.  For  instance,  to   request   help   for   the
       verify_global_plugin command, format your command like so:

          traffic_server -C "help verify_global_plugin"

       The following commands are supported:

       list   List  the  sizes  of  the  host  database  and  cache  index as well as the storage
              available to the cache.

       check  Check the cache for inconsistencies or corruption. check does not make any  changes
              to the data stored in the cache. check requires a scan of the contents of the cache
              and may take a long time for large caches.

       clear  Clear the entire cache, both the document and the host database caches.   All  data
              in the cache is lost and the cache is reconfigured based on the current description
              of database sizes and available storage.

       clear_cache
              Clear the document cache.  All documents in the cache are lost  and  the  cache  is
              reconfigured  based  on  the  current  description  of database sizes and available
              storage.

       clear_hostdb
              Clear the entire host database cache.  All  host  name  resolution  information  is
              lost.

       verify_config
              Load the config and verify Traffic Server comes up correctly.

       verify_global_plugin PLUGIN_SO_FILE
              Load a global plugin's shared object file and verify it meets minimal global plugin
              API requirements.

       verify_remap_plugin PLUGIN_SO_FILE
              Load a remap plugin's shared object file and verify it meets minimal  remap  plugin
              API requirements.

       help [CMD]
              Obtain  a  short  description  of  a  command.  For  example, 'help clear' prints a
              description of the clear maintenance command. If no argument is passed to help then
              a  list  of  the  supported  maintenance  commands  are  printed along with a brief
              description of each.

       -f, --disable_freelist

       In order to improve performance, traffic_server caches commonly used data structures in  a
       set of free object lists. This option disables these caches, causing traffic_server to use
       malloc(3) for every allocation. Though this option should not commonly be needed,  it  may
       be  beneficial  in  memory-constrained  environments  or  where  the working set is highly
       variable.

       -F, --disable_pfreelist

       Disable free list in ProxyAllocator which were left out by  the  -f  option.  This  option
       includes the functionality of -f.

       -R LEVEL, --regression LEVEL

       -r TEST, --regression_test TEST

       -l, --regression_list

       If Traffic Server was built with tests enabled, this option lists the available tests.

       -T TAGS, --debug_tags TAGS

       -i COUNT, --interval COUNT

       -m COUNT, --maxRecords

       The maximum number of entries in metrics and configuration variables. The default is 1600,
       which is also the minimum. This may need to be increased if running  plugins  that  create
       metrics.

       -M, --remote_management

       Indicates  the  process should expect to be managed by traffic_manager. This option should
       not be used except by that process.

       -n COUNT, --net_threads COUNT

       -k, --clear_hostdb

       -K, --clear_cache

       --accept_mss MSS

       -t MSECS, --poll_timeout MSECS

       -h, --help
              Print usage information and exit.

       -p PORT, --httpport PORT

       -U COUNT, --udp_threads COUNT

       -V, --version
              Print version information and exit.

ENVIRONMENT

       PROXY_REMOTE_MGMT

       This environment variable forces traffic_server to believe that it  is  being  managed  by
       traffic_manager.

       PROXY_AUTO_EXIT

       When  this  environment  variable  is set to an integral number of seconds, traffic_server
       will exit that many seconds after startup. This is primarily useful for testing.

SIGNALS

       SIGINT, SIGTERM
              On SIGINT and SIGTERM, traffic_server exits.

       SIGUSR1
              On SIGUSR1, traffic_server logs its current memory usage.

       SIGUSR2
              On SIGUSR2, traffic_server re-opens  its  standard  error  and  standard  out  file
              descriptors.
